Re: Class name as NSString and problem with NSLog?
Even further you can get the current command by using
NSStringFromSelector(_cmd); _cmd is the current selector.
You can also use NSLog(@“%s”, _PRETTY_FUNCTION”) which will give you the class
name and current selector.
Do a google search also for NSLog replacements there are ones that do a lot of
work of prepending all NSlog calls with class, function, line number and you
custom message. Like the answer here:

Given an object, and a method within, is there some way to get the name of
the class of the object as an NSString?
For that matter, what I want to do is something like this:
Class MyClass
MyClass.h
#import Foundation/Foundation.h
@interface MyClass : NSObject
...
-(void)myMethod;
@end
MyClass.m
#import MyClass.h
@implementation MyClass
...
-(void)myMethod
{
NSString *myClassName = ???; // What can I put here besides a literal
@MyClass?
NSString *fooText = [NSString stringWithFormat:@%@ -(void)myMethod,
myClassName];
NSLog(fooText); // Yellow triangle on this line
}
...
@end
so that when the myMethod message is sent to an object of MyClass, the output
should be:
timestamp: MyClass -(void)myMethod
on the output pane when debugging - timestamp just comes from the NSLog
call.
Also, when I do this (using a literal NSString constant for myClassName
above), Xcode marks the line with NSLog with a yellow triangle, and
disclosing it says something about passing an NSString instance as being
unsecure. Can this warning be turned off? It seems silly to do:
NSLog(@%@, fooText);
just to avoid this warning.
By using this strategy, if several classes implement the same message, I can
tell which instance received the message during debugging; this is handy when
iterating over containers (such as NSArray), and passing the same message to
multiple objects, or when passing messages to objects of subclasses that
override the behavior of their super.

Paged UIScrollview is acting strange in iOS7?
I have some old gallery code that uses UIScrollView in a paged mode. We are
trying to port the code to iOS7 but when we are getting strange behavior. In
iOS7 we are constantly getting scrollViewDidScroll with weird offset of
negative or some large offset that has huge exponents. Is there a known change
in paged scrollviews in iOS7? Code is simple. The image content size is hard
coded at 20 pages. The reality is its dynamic based on images coming and going.
if (_imageScroller == nil) {
CGRect scollViewRect = self.bounds;
scollViewRect.size.width += IMAGE_PADDING;
_imageScroller = [[UIScrollView alloc] initWithFrame:scollViewRect];
CGSize contentSize = _imageScroller.bounds.size;
contentSize.width *= 20;
_imageScroller.contentSize = contentSize;
_imageScroller.pagingEnabled = YES;
_imageScroller.delegate = self;
_imageScroller.clipsToBounds = YES;
_imageScroller.showsVerticalScrollIndicator = NO;
_imageScroller.showsHorizontalScrollIndicator = NO;

Re: Paged UIScrollview is acting strange in iOS7?
Seems our tool was not taking into account that the size needed to be halved
out of our photoshop template. Some reason setting the frame and content size
to 2x size of the view was causing the issue. One the scroll view was sized
properly all is now working as expected.

Question about block, ARC, self, and reference counting.
I have a question about retain cycles with ARC and blocks.
I have the following code:
__weak MyViewController* controller = self;
[UIView animateWithDuration:.25 animations:^{
controller.alpha = 0;
}
completion:^(BOOL finsihed) {
[controller showState];
}];
-(void) showState {
self.textView.text = self.stateText;
}
I have a question about what happens when I use self in showState. DId i just
cause a reference counting issue where I now have an extra retain on self and
it's not going to be cleaned up? The WWDC video say to use weak pointers to
self in the block otherwise there could be retain cycle issues. This is an
example. The utility functions are actually quite larger and called from
multiple places. I'm not creating the strong refrence via a variable because
these blocks won't be called if self doesn't exist.

No. The compiler looks at the code _in the block_ to know what the block
should retain. It doesn't (for this purpose) look inside the -showState
method. It can't even reliably know for sure that the call to -showState in
the block refers to that implementation of -showState. For example, this
code could all be called from a superclass which overrides -showState.
The WWDC video say to use weak pointers to self in the block otherwise there
could be retain cycle issues. This is an example. The utility functions are
actually quite larger and called from multiple places. I'm not creating the
strong refrence via a variable because these blocks won't be called if self
doesn't exist.
For this case, you don't even have to worry about referencing self in the
blocks directly. You don't need to use the weak copy, controller. First,
the object is not itself retaining the blocks. So, if the blocks retain
self, that's still not a retain cycle. Second, the blocks will be disposed
of when the animation completes. So any reference they hold on self is
released when that happens.

Ken

Re: ARC not ready for primetime?
I've uploaded a quick sample that shows what i have been seeing. I put some
NSLogs to show the deallocs for the NWColorViewController and NWColorLayer so
you can see dealloc being called. Load in instruments Allocations app and
switch back and forth a few times and end on the Hide tab. Basically this is
creating and destroying a color view controller (my real app does this as a
datasource for UIPageViewController). Go to the object list and filter by
NWLayerTest, you will small amounts of memory leaked where the view controller
was created and added to the subview.
This is exactly what i am seeing in my code. Bits of runtime being left behind.

but works using NSThread withe detatch thread in iOS4 with the desired effect.
My code is basically to create and generate pages for my paged scrollview in

[self configureContainer:container forIndex:index];

}

}
I cached 3 views at most. I basically have the following when the view scrolls:
- (void)scrollViewDidScroll:(UIScrollView *)scrollView;
{
[[NVGlobalQueue sharedNVGlobalQueue] cancelAllOperations];
[[NVGlobalQueue sharedNVGlobalQueue]
addOperation:[[[HVInfoCardTileOperation alloc] initWithScroller:self]
autorelease]];
}
My operations's main is:
-(void) main {
if (!self.isCancelled) {
[self setQueuePriority:NSOperationQueuePriorityVeryHigh];
[scrollerController tilePages];
}
}
} }
On iOS 3.2 i get what i expect. The third view is created and rendered as we
scroll to the 2nd one. So i have 3 views in the my scroller full rendered as I
scroll to the 2nd one. However, on iOS4 this isn't working I don't get my 3rd
one for a few seconds after its scrolled too. However if i change to:
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
[NSThread detachNewThreadSelector:@selector(tilePages) toTarget:self
withObject:nil];
}
This works great and scrolls as smooth as butter. I don't mind doing this since
there is a check to see if we have to actually create the view (could probably
make the tileView call even smarter). But why would this not work over
NSOperation on iOS4 but work in 3.2? Going to the main thread isn't an options
as it chunks the scroll And no removing the cancelAllOperations doesn't help.

Re: detecting touch and hold vs touch in UIButton
You still need that timer. Especially for non 3.2. If you get your touchEnded
before your timer is reached it was just a tap.

Hi Matt,
Thanks for your answer. Still, I don't think that solves the problem. It is
not just the difference in time what matters. If the user just taps the
button, a UISegmentedControl appears, thus this target is in touch up inside.
Now, if the user taps and holds, another type of control appears after a
delay so this has to be done in touch down (because the user is still
holding), and the user should stop holding the button when the new control
appears.
In your approach, everything is done in the userDidTouchUp, but the tap and
hold control should appear even if the user didn't stop holding. If you have
a better solution, please let me know, again thanks for your answer.

I think you want to imitate Listing 3-3 of Event Handling in the iPhone
Application Programming Guide, handling the touches yourself. m.
Okay, forget that answer. :) If the difference between touch and
touch-and-hold is just a matter of how long the time is between the touch
down and the touch up, then all you have to do is measure that time:
- (void) userDidTouchDown: (id) sender event: (UIEvent*) e {
downtime = [e timestamp]; // downtime is an ivar or global
}
- (void) userDidTouchUp: (id) sender event: (UIEvent*) e {
double diff = [e timestamp] - downtime;
if (diff 0.2) NSLog(@tap);
else NSLog(@tap and hold);
}
Obviously Touch Down is targeted at userDidTouchDown:. I think you might
want to target both Touch Up Inside and Touch Up Outside at userDidTouchUp:.
If you mean something more complex and profound by the difference between
touch and touch-and-hold, you can probably figure it out from the UIEvent,
so you'd do some more complex and profound form of event tracking here.
Anyway, I apologize for being hasty and not very clear before. What I was
really trying to say was that all your addition and removal of target-action
pairs seems unnecessary.

Re: detecting touch and hold vs touch in UIButton
I believe the way to do this is to setup a timer on touchDown to fire once
after X number of seconds. Your touchUp and touchCancelled should kill the
timer if the timer is exists and is not invalidated. If you hit the timer you
are being held. When the timer is hit you restart the timer again for the next
check.

Hi all,
I've been trying to detect touch and hold vs touch on a subclass of UIButton.
I basically accomplished that by doing the following:
I first add the following when the button is created:
[button addTarget:self action:@selector(sourceSelected:)
forControlEvents:UIControlEventTouchUpInside];
[button addTarget:self action:@selector(sourceTouchDown:)
forControlEvents:UIControlEventTouchDown];
Then in the functions:
- (void) sourceSelected:(UIButton*) sender {
// cancel request for extended meny
[NSObject cancelPreviousPerformRequestsWithTarget:self
selector:@selector(sourceSelectedExtended:) object:sender];
...
}
- (void) sourceTouchDown:(UIButton*) sender {
// give time before performing action
[self performSelector:@selector(sourceSelectedExtended:)
withObject:sender afterDelay:0.5];
}
- (void) sourceSelectedExtended:(UIButton*) sender {
// remove action from button
[sender removeTarget:self action:@selector(sourceSelected:)
forControlEvents:UIControlEventTouchUpInside];
...
...
// give time before performing action
[self performSelector:@selector(addSourceAction:) withObject:sender
afterDelay:1.];
}
- (void) addSourceAction:(UIButton*)sender {
// remove action from button
[sender addTarget:self action:@selector(sourceSelected:)
forControlEvents:UIControlEventTouchUpInside];
}
Now, this works fine, but then I thought there must be an easier (and
definitely more elegant) way to accomplish the same thing.
Can someone through me a line here?
Thank you all,

Re: How do I extract the int value from an xml node/element?
Hit send too soon . For the mac there are ways to get integer values out of the NSElement. I believe TouchXML has the same mechanism, it is a wrapper around libXML2 that mimics NSXML classes on the Mac. If using NSXMLParser you'll need to keep track of where you are at in the file and convert the value the parser:foundCharacters selector is called on your delegate. NSString has an intValue call. I would recommend doing some reading in the Apple documentation on the NSXML classes.

Re: Where to release in UIView

Re: NSData. add 6 bytes to NSData
In all honesty the easiest way is to do it in C. Add a 4 byte variable
to the top of your packet header.. When building the packet set it to
0.. That solves your problem of getting data into the packet.
But if you want to add something to the beginning, using
NSMutableData, you have to first create the NSMutableData packet with
4 bytes of 0s then call [data appendBytes].. So something like so (not
perfect)..
char bytes[4] = {0,0,0,0};
NSMutableData* data = [NSMutableData withBytes:bytes length:sizeof
(bytes)];
[data appendBytes:packet length:sizeOfPacket];
But i think you better way is to just put the 4 bytes at the top of
your packet description. When creating you can set it to 0's (first
call should be memset in your make packet call to set things to 0). If
you are reading the packet from another location you can then put the
pointer for the read or memcpy to the location of the first field.
NSData is nice but i still think most memory management things (like
creating and dealing with buffers) are better in C then thrown into an
NSData if needed.. I generally don't use NSData as 1st class citizen
for generating buffers.

Re: Missing something about initialization
A couple of things:
You are not retaining your values after retrieved (slot, svn, prn,
clock, block). These are auto released and will be released the the
next time the pool is cleaned up. (assuming you are not using garbage
collection). Not sure what your class is subclassed from, but if not
NSObject you want to a call to the super's init (or what ever the
designated initializer is).

Re: re-making connections with a different controller
One other thing to keep things simple.. Take all common functionality and put it into a base view controller class. Then subclass from there for any new controls, functionality, setup, etc. Scott On Jun 10, 2009, at 7:40 AM, Stephen Blinkhorn wrote: On 9 Jun 2009, at 22:44, Quincey Morris wrote: On Jun 9, 2009, at 19:50, Stephen Blinkhorn wrote: If you must use a tab view, you could also approach it with a view xib and a view controller to define the common part of each tab. The view controller would act as an intermediary to pass the action methods on to the correct controller. (The details, and feasibility, of this approach might depend on exactly what class of controllers you're trying to use.) That sounds interesting but will involve a near complete overhaul. Are you sure? Well, yes and no. I'm writing the GUI for a real time audio program. The back end of that is written in C++ which I've written too. The Cocoa UI is getting quite complex now but is nearly finished so I'm a bit reluctant to tear it apart. It is my first real Cocoa project though so I can't assume I've got it all right first time. Moving the contents of the tabs to a different xib file (or is it xib files? are all the tabs identical in appearance?) is straightforward. Connecting the individual controls to the view controller (File's Owner) is straightforward. Writing intermediary action methods in your view controller subclass to pass the actions on the correct controller (held in an instance variable, or set as the representedObject) is straightforward. All my tabs are identical. The current purpose of my controller objects is to map the value from a control onto a nonlinear range. I display the nonlinear value in the UI for user feedback and then pass it to the C++ audio side. There are a number of controls within in each tab(s) which require a custom mapping and differ from controller to controller based on some user selection. Currently I deal with this by dynamically allocating/deallocating a kind of sub controller object of the required type at that time. The only real work happens in (say) your window controller's awakeFromNib method. In that method, you would create as many view controllers as there are distinct tabs, passing the correct action controller object as a parameter, and letting the view controller instantiate its nib. Then, for each view controller, replace the appropriate tab subview with the view controller's view. That doesn't require any design changes anywhere else in your application, AFAICT. It also has the advantage of making your life really easy if you ever have to add one more control to all of the tabs. I know I will be adding and changing things over the next few months so I think it will be worthwhile putting the time in to implement something like this. It isn't so much the tedium of manually connecting things together but the inevitability that a few connections will go astray at some point. I did try something with bindings but it quickly got out of hand for me. Can I make connections programmatically? That might be easier for now.

This may sound like a newbie questions but never had this issue before.. I am trying to add a tag ID to an NSOutlineView thats in one view controller. In another view controller is a table view. I listen to NSOutlineViewSelectionDidChange notifications and fill the table based on the selection. This listens to all outline views (even the open file panel). So i put a tag id on my NSOutlineView and wanted to check for that particular tag. But it always comes up 0. I have a work around for this by listening for selection changes in the tree controller and firing off a notification based on what was actually selected. I am now just curious about the NSOutlineView and the tag field. I couldn't find anything that said you couldn't tag a outline or table view control.

Re: NSTabView; How to get the current / active tab ..?
Why not use unique identifiers for each tab item? Each NSTabViewItem
has an identifier value. Using that and some defines you can use do
the following:
#define GENERAL_TAB 1
#define FONT_TAB 2
NSTabViewItem* tabViewItem = [tabView selectedTabViewItem];
switch([tabViewItem identifier])
{
case GENERAL_TAB:
NSLog(@1);
break;
case FONT_TAB
NSLog(@2);

NSTreeController and CoreData question
I am working on a CoreData project but want some advice on using an Outline View. My relationships are setup like so. They don't have a parent/child entry. The entries more match the read data. Project // just a simple group node will say (targets/sources) in localized languges. TargetGroup (one to one to TargetGroup) SourceGroup (one to one to SourceGroup) TargetGroup Targets (one to may to targets) SourceGroup Sources(one to many to sources). Sources Language Entries (one to many to entries) Target (one to many to targets) Tragets Sources (one to many to sources) I know i have a few options. 1.) Create a generic NSTreeNode subclass the does the right thing based on node type and gets the proper children,parent,etc... 2.) Change my model to a generic children/prarent node type. 3.) Subclass NSManagedObject to do the right thing based on type. 4.) Create a protocol that each object must override to give the proper data. 5.) Use a data source. I think what makes this tricky is that this isn't just a simple one to one relationship and is what is throwing me off. I am leaning towards 1 and 3. I would like to keep this model due to the fact that it represents the real data. I may also be over thinking this a bit.. Any advice would be appreciated.

CoreData and NSOutlineView.
I have a question, may know the answer already. I am looking at using core data to store the project for my application I am starting. I want a categorized NSOutlineView that has categories and then children under. The categories just describe the nodes underneath it. They do not not necessarily match 1 to 1 my entities. From what I am seeing on the web it is better that I use a data source for my tree than trying to get bindings to work. Am i missing out on something not using bindings? I have seen also seen that it takes a lot of work arounds to get NSTreeController to work properly with NSOutlineView. This is my first adventure into core data.

Re: Which language to get started with cocoa development?
Personally I would say Objective-C. Its not that difficult of a language to learn. If you have learned C++ and C, Objective C is easy enough to learn. I just trained and mentored some window's engineers on an Objective-C project, they had C#, C++ and C expreience. Once they got through the syntax differences and the memory management, they love the language and framework, the tools are a love hate relationship. The Objective-C language, i believe, will run faster than a python or mono app. They require an interpreter for the bit code. They don't compile to native code, i don't believe.

How well does a layered back OpenGL view work on Macbooks and Mini's with the integrated Intel chipsets.

Re: NSView subclass
If its a delegate you would want to check if the delegate handles the selector with respondsToSelector and the use performSelector to make the call.

However we get errors when loading data if the model file is not included in the application and is just in the framework. I looked through the docs and couldn't find any help. Are there any tricks to having the data model file (.mom) exist in the private framework and not in the application's resources?
