cocos2d for iPhone

   Has anyone used the default popup mechanism with cocos2d? I am writing a board game (my first) that doesn't necessarily need my own custom popups--figured that any extra HIG features I have could only help.

   After a couple (dozen?) failed attempts, I've been able to generate a popup on helloWorld thanks to the example at http://blog.blackwhale.at/2010/04/show-a-custom-popover-view/
   I've been able to use the following as a CCMenu callback:

   -(void) actionPerformed:(id)sender {
   NSLog(@"called actionPerformed");
   //build our custom popover view
   UIViewController* popoverContent = [[UIViewController alloc]
   init];
   UIView* popoverView = [[UIView alloc]
   initWithFrame:CGRectMake(0, 0, 200, 300)];

   popoverView.backgroundColor = [UIColor greenColor];
   popoverContent.view = popoverView;

   //resize the popover view shown
   //in the current view to the view's size
   popoverContent.contentSizeForViewInPopover =
   CGSizeMake(200, 300);

   //create a popover controller
   UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];

   //present the popover view non-modal with a
   //refrence to the button pressed within the current view
   [popoverController presentPopoverFromRect:CGRectMake(200, 200, 200, 200)
   inView:[[CCDirector sharedDirector]openGLView]
   permittedArrowDirections:UIPopoverArrowDirectionAny
   animated:YES];

   //release the popover content
   [popoverView release];
   [popoverContent release];
   }

   But I have absolutely no luck trying to run a CCLayer inside the UIView while the main window is still the current scene. If all else fails, I may just take the easy way out and build things in interface builder. But my OCD still wants me to get this working.

   Can anyone help?

   Bump

   Is anyone even using any HIG recommendations, or are we just taking the "we're games--we're exempt" stand?

   hi,

   here is some code I use to use a choose a photo from the library on the iPad and the iPhone. Perhaps it can help you since I use a popover.
   Please note that there is no direct reference to UIPopoverController (I use id) because I am creating an universal app. So the code is checking if it is an ipad or not.

   This code is running inside a CCLayer

   NOTE THAT IT IS "ALPHA" CODE (from thos afternoon). I've not tested it extensively!

   id *_popover;
   UIImagePickerController *_picker;
   
   -(void)pickPhoto:(UIImagePickerControllerSourceType)sourceType{
   
   	[[CCDirector sharedDirector] pause];
   	[[CCDirector sharedDirector] stopAnimation];
   
   	//for IPAD
   	if ([ [ [UIDevice currentDevice] model]  rangeOfString:@"iPad"].location != NSNotFound){
   
   		_picker	= [[UIImagePickerController alloc]init];
   		_picker.delegate = self;
   		_picker.sourceType = sourceType;
   		_picker.wantsFullScreenLayout = YES;
   
   		//to work with 3.1 we cannot create the class directly
   		_popover = [[NSClassFromString(@"UIPopoverController") alloc] initWithContentViewController:_picker];
   		[_popover setDelegate:self];
   
   		CGSize winsize = [[CCDirector sharedDirector] winSize];
   		[_popover setPopoverContentSize:CGSizeMake(winsize.width,winsize.height) animated:NO];
   
   		[_popover presentPopoverFromRect:CGRectMake(0,0,10,10)  inView:[[CCDirector sharedDirector]openGLView]
   				permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
   
   	}
   	//iPhone
   	else{
   		_picker	= [[UIImagePickerController alloc]init];
   		_picker.delegate = self;
   		_picker.sourceType = sourceType;
   		_picker.wantsFullScreenLayout = YES;
   		[_picker presentModalViewController:_picker animated:YES];
   
   		[[[CCDirector sharedDirector] openGLView] addSubview:_picker.view];
   
   	}
   }
   
   -(void)imagePickerController:(UIImagePickerController *)picker
   didFinishPickingMediaWithInfo:(NSDictionary *)info{
   
   	CGSize winSize = [[CCDirector sharedDirector] winSize];
   	UIImage *newImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
   	CGSize imgsize=[newImage size];
   
   	//resize it if it is larger than the screen
   	if (imgsize.width>winSize.width){
   
   		newImage=[self imageWithImage:newImage scaledToSize:CGSizeMake(winSize.width, imgsize.height*(winSize.width/imgsize.width)) ];
   	}
   	else
   		if (imgsize.height>winSize.height){
   
   			newImage=[self imageWithImage:newImage scaledToSize:CGSizeMake(imgsize.width*(winSize.height/imgsize.height),
   																		   winSize.height) ];
   		}
   
   	// Dismiss UIImagePickerController and release it
   	[picker dismissModalViewControllerAnimated:YES];
   	[picker.view removeFromSuperview];
   	[picker	release];
   	//remove image if already exist
   	[self removeImage];
   	// Let's create a sprite now that we have an image
   	_imageFromPicker = [CCSprite spriteWithCGImage:newImage.CGImage];
   	_imageFromPicker.position= ccp(winSize.width/2,winSize.height/2);
   	[self addChild:_imageFromPicker z:0];
   
   	if ([ [ [UIDevice currentDevice]
   		   model]
   		 rangeOfString:@"iPad"].location != NSNotFound){
   
   		[_popover dismissPopoverAnimated:YES];
   		[_popover release];
   	}
   
   	[[CCDirector sharedDirector] startAnimation];
   	[[CCDirector sharedDirector] resume];
   }
   
   - (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
   {
   	// Dismiss the image selection
   	[picker dismissModalViewControllerAnimated:YES];
   	[picker.view removeFromSuperview];
   	[picker	release];
   
   	[[CCDirector sharedDirector] startAnimation];
   	[[CCDirector sharedDirector] resume];
   }
   
   //for Ipad UIPopoverController if there is a cancel when the user click outside the popover
   - (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController{
   
   	[_picker dismissModalViewControllerAnimated:YES];
   	[_picker.view removeFromSuperview];
   	[_picker	release];
   
   	[[CCDirector sharedDirector] startAnimation];
   	[[CCDirector sharedDirector] resume];
   }

   DrPedro,

   I didn't want to be rude and not thank you. I have been out of commission this week and am only starting to look at your method now.

   Will post my results.

   eventually...

   thanks

   I find that popoverControllerDidDismissPopover is never called. I assume that inView:[[CCDirector sharedDirector]openGLView] is the cause. When the UIPopupViewController is dismissed automatically nothing gets dealloc'd. Anyone figure out how to make this work?
