How to Identify if the device is used in iAD supported Regions
I am planning to use iAD for my iOS application. As the iAD available only in USA,UK,France,Italia,Deutschland,España AppStores. I want to display iAD only for supported regions. This will avoid displaying "Test Advertisement" from iAD.I can use AdMob for all other regions. I am not sure, how to identify the iOS Device is used in supported region? Any help is highly appreciated. Thanks Sasikumar JP ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I find short-circuit evaluation easier to read and much more concise, and, of
course, it's always nice to avoid unnecessary levels of nesting.

This I agree with. I "know"[1] about the short-circuiting behavior of && and
still I'd prefer the conditional flow be super-clear rather than have to think
about operator rules even a tiny bit. But now we're back where we started.

Well, that part's true :)
I seem to recall I failed that question, the only one I did. So I got the
lecture and never questioned it. I did get that job anyway, though in hindsight
I'd rather I hadn't, but that's another story...
I think the point they wanted to get across was that they didn't want to see
code like this:
if( someFunction() && someOtherFunction()){ ... }
instead of:
if( someFunction())
{
if( someOtherFunction())
{
}
}
where (they claimed) in the first case someOtherFunction() may or may not run
depending on compiler implementation, and not dependent on the result of
someFunction().
On the other hand, this was easily 15 years ago, maybe I've just forgotten the
question and what it was all about. It happens - I forget so much stuff these
days.

Correct way to use contextInfo with ARC
Hi All,
A case of me not grasping C or/and ARC;-)
I'm trying to pass the NSMutableArray across the void to the didEndSelector so
I can access it if the user clicks ok.
/snippits
NSMutableArray *someInfo = [NSArray arrayWithObjects:@"made" , @"it",
@"across",. nil];
[holdAlert beginSheetModalForWindow:[self window] modalDelegate:self
didEndSelector:@selector( alertDidEnd:returnCode:contextInfo: )
contextInfo:?how to send someInfo?];
-(void)alertDidEnd:(NSAlert *)alert returnCode:(int)returnCode
contextInfo:(void *)contextInfo
{
// not happy maybe use a sheet and block
NSMutableArray *holdArray = ?contextInfo?;
what magic do I use to pass it in and get it out;-)

Re: Unnecessary Boolean Warning
The C99 spec I can find on the net has 6.5.13 (3) and (4). 3. The && operator shall yield 1 if both of it's operands compare unequal to 0; otherwise it yields 0. The result has type int. 4. Unlike the bitwise binary & operator, the && operator guarantees left-to-right evaluation; there is a sequence point after the evaluation of the first operand. If the firt operand compares equal to 0, the second operand is not evaluated. To my reading, and unless I have a totally bogus spec, that makes exactly the guarantee Jean-Daniel claims.

Incorrect. The C language guarantees short-circuit evaluation for '&&'. The left side is evaluated first. If it is false, then the right side is not evaluated. '||' and '?:' similarly guarantee short-circuit evaluation. You're correct for all other operators. '&' does not guarantee short-circuit evaluation or any particular order of execution.

The second operand is evaluated only if the first compares unequal to 0; the third operand is evaluated only if the first compares equal to 0; the result is the value of the second or third operand (whichever is evaluated), converted to the type described below.95) If an attempt is made to modify the result of a conditional operator or to access it after the next sequence point, the behavior is undefined." -- Greg Parker gpar...@apple.com Runtime Wrangler ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

if your IKImageBrowserView DnD delegate does not implement -draggingUpdated:
(because you commented it out) then IKImageBrowserView makes it's own best
guess for drag operation. You must implement -draggingUpdated: and return the
appropriate value.

There are actually 3 methods concerned with the drop…
-prepareForDragOperation:, -performDragOperation:, and
-concludeDragOperation:. In prepare you can make one last determination and
decide if you really can accept the drop of not. If you return NO, then the
drag is cancelled and perform and conduced are not called. In
-performDragOperation:, you should actually update your data modal and return
if this was successful or not. If you return NO, conclude is not called. In
-concludeDragOperation:, you do any clean up that you need to do (like call
setNeedsDisplay or reload). Often you only care about -performDragOperation:
and should only implement that one.
In Lion, these 3 methods additional meaning and responsibilities when you are
dealing with multi-image, animated drag and drop. In -prepareForDragOperation:
you inform the draggingInfo if you want to animate the drop (by modifying
properties on sender, the return value still has the same meaning discussed
above). If so, then in -performDragOperation: you update your data modal and
setup drag item destinations and any animations that you view needs to perform
to create drop holes. On return, the drop animation is performed and then
-concludeDragOperation: is called. In -concludeDragOperation:, you should
invalidate where you are drawing holes and do any needed cleanup, such that
the next call to DrawRect will draw the final version of the dropped items in
place.

UIViewControllers are not designed to have their views inside other arbitrary views (except for the previously mentioned UINavigationController, etc...). For more detail, there was a WWDC session on "Implementing UIViewController Containment". To add a text field (or other arbitrary views) "along side" the table view, you have a couple of choices: - Put it in the table view header view. Disadvantage is that it can get scrolled off screen - Put the view in a row in its own section. Similar to previous - Put it in the first section's header view. Only works well if you have a single section, are in non-grouped mode - Put the view into the navigation controller's title view. Limits the height of your view, and assumes you've got a nav controller, and aren't already using the title You can also play games where you add the view to the tableview itself, and, since the tableview is a scrollview, adjust the content to allow that item to show, and then, upon scrolling, make sure the view is on the top of the screen (both in Y and Z coordinates, since the table view may have made a new cell that ends up layered covering your view) Glenn Andreas gandr...@gandreas.com The most merciful thing in the world ... is the inability of the human mind to correlate all its contents - HPL ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

UITableViewController, with table view not the root of its nib?
I’ve got an iOS screen that incorporates a UITableView. This screen is run by a UIViewController subclass. I’d like to subclass UITableViewController instead, to get more table behaviors for free. The problem I’m running into is that the table view is not the root view of my nib. (There’s a text field above the table that’s a sibling of it.) As far as I can tell, UITableViewController only works when the table is the root of the nib. It does have a separate ‘tableView’ property, but this isn’t an IBOutlet so there’s no way to wire it up to the table view in the nib. Instead, the class assumes that the ‘view’ outlet — which must point to the nib’s root view — is the table view, and raises an assertion failure otherwise. I’m trying to figure out a way around this, but every workaround I think of makes the project more complicated, canceling out the benefit of switching to UITableViewController. Is there a clean way of doing it that I’m missing? —Jens smime.p7s Description: S/MIME cryptographic signature ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

New allowsExternalBinaryDataStorage in Core Data
Hello, I looked at the Core Data release notes of Lion, I also looked the "What's new in Core Data on Mac OS X" video of the WWDC 2011. And I have a question about the new allowsExternalBinaryDataStorage option for binary attribute. I did some test with an attribute for images. I can see that when I put an big image in the data, the file did not grow. But where the external file/data is put? If the file is moved or copied, what about theses external data? I tried to find info, but the documentation is very sparse. Frédéric___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

[RESOLVED] NSSegmentedControl
So I set the images for seg 0 and seg 3 to those for seg 1 and seg 2 which were displaying All segs now display an image So, I made all images the same size as those that displayed. I noticed that one image that did not display has a resolution of 88.xxx pixels/inch the others were 72.01 so I made them all the same. Now each seg has a correctly displayed image. Weird, as this has worked on many machines and OSXv10.5.8 up to Lion with the exception of this one machine.

Drawing text like Lion's Mail
Hi,
In the new Mail, when there's no selection, the detail's view show "No Message
Selected" in an what seems to be embossed text. My various attempts to emulate
that, have failed. Well it kinda work but it's a bit ugly.
Here's what I've done:
- (BOOL)isFlipped
{
return YES;
}
- (void)drawRect:(NSRect)dirtyRect
{
[[NSColor whiteColor] set];
[NSBezierPath fillRect:[self bounds]];
[[NSColor grayColor] set];
[NSBezierPath strokeRect:[self bounds]];
// draw image
CGFloat imgW = [banner size].width;
CGFloat imgH = [banner size].height;
CGFloat centerX = [self bounds].size.width / 2.0f;
CGFloat centerY = [self bounds].size.height /2.0f;
CGFloat x = centerX - (imgW / 2.0f);
CGFloat y = centerY - (imgH / 2.0f);
NSRect rectToDraw = NSMakeRect(x, y, imgW, imgH);
NSRect imgRect = NSMakeRect(0.0f, 0.0f, imgW, imgH);
[banner drawInRect:rectToDraw fromRect:imgRect operation:NSCompositeCopy

draggingEntered Not Working As Expected
XCode 4, 10.6 GC -- I have an IKImageBrowserView which I have implemented drag
and drop for. I have set my view controller as the image browser's drag
delegate, registered for pasteboard drag types in awakeFromNib and implemented
DnD protocol methods like so...
-(void)awakeFromNib
{
[myProductImageBrowser registerForDraggedTypes: [[NSArray
arrayWithObjects:@"productIndexObjectType",NSFilenamesPboardType, nil]
arrayByAddingObjectsFromArray:[NSImage imagePasteboardTypes]]];
}
-(NSDragOperation)draggingEntered:(id )sender
{
NSLog(@"DND Entered");
return NSDragOperationNone;
}
-(NSDragOperation)draggingUpdated:(id )sender // validate
position
{
NSLog(@"DND Uppdated");
if ([myProductImageBrowser dropOperation] == IKImageBrowserDropOn)
{
return NSDragOperationEvery;
}
return NSDragOperationNone;
}
-(BOOL)performDragOperation:(id )sender // Drop Occured
{
NSLog(@"DND Perform");
NSArray *theFileArray = [[sender draggingPasteboard]
propertyListForType:NSFilenamesPboardType];
if ([theFileArray count] == 1)
{
NSImage *theImage = [[NSImage alloc]
initWithContentsOfFile:[theFileArray objectAtIndex:0]];
if (theImage)
{
TKProductMaster *theProductMaster =
[[myProductMasterArrayController arrangedObjects]
objectAtIndex:[myProductImageBrowser indexAtLocationOfDroppedItem]];
[theProductMaster setMyImage:theImage];
[theProductMaster setImageVersion:[theProductMaster
imageVersion] + 1]; // up the version number so the image browser knows to
trash onld image cache
[myProductImageBrowser reloadData];
return YES;
}
}
return NO;
}
QUESTION #1
I will test for the other pboard types later, but right now what is confusing
me is that draggingEntered, which returns NSDragOperationNone, is not stopping
anything. The logs are showing so it is getting called. I did read in the
NSDraggingDestination Protocol Reference that draggingUpdated & draggingExited
will still get called even if draggingEntered returns NSDragOperationNone.
Okay, but when I comment out draggingUpdated the image browser still accepts
drags. Why? Shouldn't it cut off dragging altogether if draggingUpdated is
never called to return NSDragOperationEvery?
QUESTION #2
I do not understand the difference between prepareForDragOperation: and
performDragOperation: as they both seem to be called at the same time and have
access to the same sender / info. As it is, I am only implementing
performDragOperation to validate the final drop and perform the final work.

When I get an only-works-on-my-machine problem, the first thing I do is check for hardcoded absolute paths. I.e. did the segmented control’s image names somehow get set to absolute paths instead of names? It’s also worth checking capitalization of the image names, in case the remote system has a case-sensitive filesystem (unlikely but possible.)

You should be changing the scroll view frame, but you make it sound like you're changing the table view frame. Also, check that you've enabled column resizing correctly in *both* places -- the column resizing behavior of the table view itself (it's a popup -- resize first column/resize last column/etc) AND the resizing behavior of the column (it's a checkbox prior to Xcode 4 IIRC, and a popup in Xcode 4). ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

finding my UIViewController
I feel I've asked this question before but google doesn't think I have. My code is dealing with a button press in a control on a UITableViewCell in a UITableView which is contained in another UIView subclass and on and up through several views until eventually there is a topmost UIView which was presented from a UIViewController subclass. I want the button press to pop up a modal UIImagePickerController which will eventually pick the image for the cell I'm in. To pop it up I need a UIViewController instance to pop it up from, and to pop it down again afterwards. Is there any way to find, given a UIView, what the closest presenting UIViewController is? I tried going the other way, used [ [ UIView window ] rootViewController ] to pop up the image picker, that pops it up fine, but popping it down leaves a black screen, not really surprising, that's not the UIViewController which was really the controller at the point I pushed it, that's the root one, there's a few on the stack after that. I wasn't able to find a way to navigate down the UIViewController stack to find the bottom one, even if I could it sounds a bit fragile. Do I really need to pass the UIViewController down through why whole view hierarchy to my UITableViewCells so they know what to use for a modal popup and down; or crawl upwards superview by superview until I find one which perhaps implements some interface telling me it knows what the UIViewController which presented it was? I must have missed a method somewhere which does this. This is iOS 4.x on the phone. ___ Do not post admin requests to the list. They will be ignored.

NSTableView with autoResizing Column: How to trigger auto-resizing after setFrame:?
Hello all, I have a window covered with an NSTableView inside an NSScrollView. The tableview has a single column which is set to autoresize with the tableview. This works as expected when I resize the window, the column extends correctly to fill the newly available space. Now, what I'm trying to do is resize the tableview horizontally inside the scrollview *without* changing the size of the window itself[1]. I can do that easily enough by modifying its frame, but this seems to ignore the column auto-resizing and leaves the column at the original width. Of course, I could just set the new column width explicitly, but I'm trying use the autoresizing so that I can use NSViewAnimation to animate this transition. Any ideas on why the column autosizing doesn't work when setting the frame directly? I tried calling various NSView and NSControl methods to force a relayout after changing the size, but had no success. Thanks, Daniel. [1] Why? My column content stretches out to fill all available space and display a higher resolution representation, and I want to have a zoom operation that shows content in more detail (albeit only in 1 dimension) without changing the current window dimensions.___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Yes, you have to use it if you want your app to run on 10.4. For extra points, check at runtime if the newer method is available, and use that instead.

Deprecation is your warning that at some point in the planned future this routine is going away. You should be looking for a replacement. If you still need to support an OS version for which no suitable replacement is available or constructible then use it, but it's best to do so conditionally - use some mechanism provided by your compiler and/or runtime environment to use the new API if available and the old only when necessary. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: How to detect Time Machine volume?
I agree that the idea is to skip the Time Machine directory (current or old), not the entire partition.

Re: Unnecessary Boolean Warning
You are correct. I get that wrong a lot. But that reinforces my point. A decent language (IMHO) would not confuse things with two different "and's". And my typo "'1001'" for "OX1001" probably was a Freudian slip because of my fervent dislike of C's syntax for hex numbers. Or maybe it was too late into the wee hours. - Dale Miller On Aug 2, 2011, at 23:43 , Charles Srstka wrote: On Aug 2, 2011, at 7:57 PM, Dale Miller wrote: It is disconcerting that if A = 0x'0110' and B = '1001' then A & B returns true but A && B returns 0, so "if (A && B)' is executed, the 'true' leg is not taken Don’t you have that backwards? Assuming B was supposed to be hex, i.e. 0x1001, then A & B would be 0, whereas A && B would be true.

Deprecated methods usage
