[SOLVED] Drag from Table To View

2010-09-25 Thread koko 
This began to work when I changed the base class and initializer for  
the table cell from NSCell and -init to NSTextFieldCell and - 
initTextCell.

Well thank you Seth, you are correct.

I should have said that


- (BOOL)tableView:(NSTableView *)aTableView writeRowsWithIndexes: 
(NSIndexSet *)rowIndexes toPasteboard:(NSPasteboard *)pboard



is never called. And as I understood only this method and this

need to be implemented / called for a drag session to start from a

This should fix the problems at least some folks have been having with the iOS 
4.1 SDK.  It also includes bug fixes from the two 985 sneakypeeks.

Many thanks to Gerriet Denkmann for finding and fixing the bug.

Any problems (for example, I've only tested on Snow Leopard), please let me 
know.

Three problems with CATiledLayer on 10.5

2010-09-25 Thread Gideon King 
Hi All, I've run into three fairly basic problems with using CATiledLayer on 
10.5. All of these things work fine in 10.6, but unfortunately I have to 
support 10.5 too. It is a layer hosting view in a scrollview, with a layer that 
is a CATiledLayer.

1. When my CATiledLayer is 5,000 x 5,000 pixels, it doesn't draw, but at 2,000 
x 2,000 it does. In my application, 5,000 x 5,000 would be reasonably common. 
How do I get it to work with larger sizes like this?

2. I want to do all the drawing in a flipped coordinate space, but if I do 
either 
[holderLayer setAffineTransform:CGAffineTransformMakeScale(1.0f, 
-1.0f)];
or
holderLayer.transform = CATransform3DMakeScale(1.0f, -1.0f, 1.0f);
It stops drawing completely. How do I flip my coordinates?

3. I want to have the center of the coordinates at the center of the layer, so 
I set the bounds origin to negative half the width/height, but when I do that, 
my background fill which just fills the bounds doesn't draw, and my tiled image 
drawn with CGContextDrawTiledImage only draws the image for a brief moment when 
you scroll the view. How do I move the bounds origin?


Thanks

Gideon

Usually the better approach is to pick a time at which it makes sense to remove 
the object from the array. For example, if you were writing a socket wrapper 
class and needed to keep a global array of all socket objects, you might add 
the object to the array in -init, and remove it in -close.

If you can't find a good method to use, I'd advise adding one specifically for 
this purpose. We have a few of these, and typically call them -invalidate. As 
long as everyone plays by the memory management rules, no overrides of -retain 
or -release are required, and calling -invalidate breaks the retain cycle that 
would otherwise keep the object alive.

I would not recommend playing fancy memory management tricks in -init or 
-dealloc. You're likely to make a mistake (memory management is a noodly enough 
topic already), and they will make your code more confusing in a garbage 
collected environment.

Class Instance Storage

2010-09-25 Thread Richard Somers 
I need a class, in which an instance of the class, can access all  
other instances of the class.


In the following code, instances of the class are stored in a static  
mutable array. To make the code work, the instance must released after  
adding it to the array and retained before removing it from the array.  
Otherwise dealloc will never be called, and instances will never be  
removed from the array.


// MyClass.m

static NSMutableArray *_array;

@implementation MyClass

+ (void)initialize
{
_array = [[NSMutableArray array] retain]; // Is retain correct  
here?

}

- (id)init
{
self = [super init];
if (self) {
[_array addObject:self];
[self release]; // ???
}
return self;
}

- (void)dealloc
{
[self retain]; // ???
[_array removeObject:self];

[super dealloc];
}

@end

This code seems to work fine. Is there a better way to do this?

Drag from Table To View

2010-09-25 Thread koko 
Earlier this I got help on dragging from  NSView to NSView .. got it  
working just fine.


Made some changes and want to drag from a Table to the same view I had  
accepting drops previously.


I do this in my table sub class awakeFromNib

[self registerForDraggedTypes:[NSArray arrayWithObject:@"Obstacles"]];

and I implement

- (BOOL)tableView:(NSTableView *)aTableView writeRowsWithIndexes: 
(NSIndexSet *)rowIndexes toPasteboard:(NSPasteboard *)pboard {



NSLog(@"writeRowsWithIndexes %@", rowIndexes);

	NSData *zNSIndexSetData = [NSKeyedArchiver  
archivedDataWithRootObject:rowIndexes];
	[pboard declareTypes:[NSArray arrayWithObject:@"Obstacles"]  
owner:self];

[pboard setData:zNSIndexSetData forType:@"Obstacles"];

return YES;
}


which as I understand the docs is all that is required to have a table  
as a drag source.


But, It don't work so what now brown cow?

Thanks -koko

Re: In-app SMS

2010-09-25 Thread Mark Woollard 
My understanding is that although you can compose an SMS with multiple 
recipients in iOS 4.0 ready for sending the user still has to interact and 
touch the actual send button on the compose screen. An app cannot send SMS 
messages without the user being involved and having the chance to approve both 
the recipients and the message contents.

The fact that Apple provides a public API for composing and sending SMS 
messages would suggest that they permit apps to use it.

As for your particular use, the approval process is less opaque than it had 
been, but the only definitive guidance on what Apple will do is whatever Apple 
does. They have published their guidelines; they're behind an ADC login, so I 
won't try to guess at the answer to your question (and a good thing, too), but

Why would you want to? NSTableView is a view — it cares only about the rows and 
columns it has to draw. It doesn't need to know the values behind parts of the 
table that aren't visible. It doesn't keep those values, it only pulls them out 
of your code and draws them. In practice, so far as the table view is 
concerned, those parts don't even exist. If you want to evaluate other parts of 
your model, have your model do it itself.

Hmm, you're right about the Settings app.  I guess I should verify such
things before blurting them out.  I could have sworn I saw such an
implementation, but now I can't remember where.

While searching around for the above behavior, I did come across another
paradigm that you can consider.  ADA-winning OmniFocus lets you edit
projects and contexts by entering edit mode via a UIBarButtonItem (as
you intended), followed by simply tapping the row.  They use the
standard delete controls as well (which it sounds like may not be
applicable in your situation).  Not sure how intuitive this approach is,
but it is one way people solve your problem.

My recommendation, since all of the approaches are easy to implement, is
just to create mock-ups with all three and hand them to different target
users and see which lets them figure out usage easiest.  (Nothing beats
an experiment.)

In-app SMS

2010-09-25 Thread Dan Hopwood 
Hi all,

I found the following link with info on how to send SMSs from within an
application.

http://blog.mugunthkumar.com/coding/iphone-tutorial-how-to-send-in-app-sms/

I have not tested this yet but have the following question. If the above
does work, do Apple allow applications onto the App Store that use such a
technique or does it depend on the context. For example, it would make sense
that Apple reject an application that spams the users contacts on every
launch but perhaps not for an app that replies on sending SMSs for it's
purpose.

Thanks in advance for any advice.

Yes--don't make assumptions about how the API works. You'll just end up saying 
something nonsensical, and respondents can't do much more than point that fact 
out.

Also, if you want useful answers to questions, you need to explain specifically 
what you need to accomplish, and the conditions under which you need to 
accomplish it. E.g., bindings will usually change an entire scenario.

What, specifically, don't you get? What method calls have you tried? Have you

Re: Converting an AttributedString into NSData for an NSTextView

2010-09-25 Thread Brad Stone 
I've been programming in Cocoa for 12 months now so I may not understand the 
subject fully but my NSTextView Data binding is connected to a Core Data 
attribute of type "Binary Data" (NSData) and this works when I manually type in 
text, set some attributes like underline or font, save it and reopen it.  

Since I have 4,000 files to cycle through I want to do this all 
programatically.  To simplify things I tried to do this with an NSString 
instead of an NSAttributableString.  I wrote a test app that creates a new 
document, pulls the entity "newNote" and uses the following code to set the 
NSData object:

NSData *noteData = [s dataUsingEncoding:NSUnicodeStringEncoding]; 
[newNote setValue:noteData forKey:@"noteData"];

I then save the document and loop around again.  This works fine with the 
NSString.  After the 4,000 are loaded in, if I open one of the documents in my 
interface and look in the textView I see the string.  I guess don't fully 
understand how to repeat this process with an AttributedString.  I don't see 
how NSTextStorage applies in this scenario.  Maybe I'm skipping a step.

NSTextView doesn't use NSData as its "data source"--it uses NSTextStorage. You 
can get its content as a mutable string using -mutableString and manipulate it.

Converting an AttributedString into NSData for an NSTextView

2010-09-25 Thread Brad Stone 
I have an NSMutableString that I want to set as the NSData source for an 
NSTextView.  I'm stuck and don't know how to do it.   I'm importing about 4,000 
XML files and I have to programmatically create the attributedString for each 
one, there's no way around it.

How do I convert an NSMutableString to NSData so it can be the data source for 
an NSTextView?

Thanks___

Re: What would cause my animation's delegate methods to not be called?

2010-09-25 Thread Gideon King 
As another data point, I have run exactly the same code on 10.5, and the 
animation delegate methods are called there.
