I'm sure I'm overlooking the obvious as I've got countless working buttons...but...for whatever reason this one is not cooperating... I've added a UIButton (Rounded Rect) to a UIView subclass (DialogView) which is a subview of my view controller's view. This subview is created almost entirely in IB. I've wired up the button to (IBAction...
Hi I want to perform a shrink animation on a UITableVIew. I experimented a bit and found out that the animation runs much faster when I shrink a UIImageView with an image of the current state of the tableview instead of shrinking the table view itself. I grabbed the image in a method in my main viewcontroller prior to the animation: UI...
Hey guys, You probably all know the famous virtual zippo app. I thought of making such an app too, just for learning objective-c. THe developer said he has used a video of flame. How is it possible to play a video inside a UIView? DO you have any ideas of how to achieving that? Thanks in advance! ...
I'm trying to add a progress meter, or other "I'm busy right now" notification to my view hierarchy right before doing some intense computation that will block the UI. My code looks some thing like: //create view [currentTopView addSubView:imBusyView]; //some initialization for the intense computation [computation startComputing]; U...

I have two view controllers: MyParentViewController and MyChildViewController. The application starts with MyParent. I push the MyChild controller to the top of the navigation stack, so that the chain is like so: MyParent > MyChild I log the object ID of MyChild with NSLog(@"%p", self): 2009-11-20 05:08:29.305 MyApp[2213:207] MyChil...
I have multiple UIView animations running in my app. They are very short, and then make callbacks to a method that then usually fires off another animation. This leads to a lot of little animations running at the same time, each firing back callbacks. This actually performs pretty well, and for the first few levels (the app is a game)...
I'm programatically creating a custom section header for a table that has a width set to 290. When I use a UIImageView containing a 290 x 29 PNG directly the image appears correctly. However, I'm refactoring to include a UILabel so I can do some custom text so I place the UIImageView and UILabel in a UIView. When I view this version, ...
Hi guys!! I'm developing an app for iPhone using a coverFlow view, when the app is building the cards it is using a UIView in order to add labels and other stuff. Then I convert the UIView into UIImage using the following code: UIGraphicsBeginImageContext(imageView.bounds.size); [imageView.layer renderInContext:UIGraphicsGetCurrentCon...
I have a UIView that's starting about 600 pt's off the screen, but when it comes on to the actual frame, it seems to be disabled. I've tried using a UIScrollView, but also can't because I need to access the touchesBegan and touchesMoved methods form my UIView, so how would I enable interaction after it comes back on to the screen. And...
Hello, This problem has just come up when I cleaned all targets and soft resetted (held home & power for about 10 seconds) my iPod Touch (2nd gen). It looks like the view might be rotated portrait. Here is a pic of the problem: The view is linked to a XIB file, and I setup landscape in interface builder. I also use <key>UIInterface...
I have a view that is added as a subview in a viewcontroller. The subview has delegates methods and the viewcontroller is assinged as its delegate. The subview has a animation and calls a delegate method when the animation is finished. The problem is that when the viewcontroller is removed from the view by the navigationcontroller the s...
As far as I have understood so far, every time I draw something in the drawRect: of a UIView, the whole context is erased and then redrawn. So I have to do something like this to draw a series of dots: Method A: drawing everything on every call - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext();...
I'm developing an iPhone app where I have my HTML content loaded in a UIWebview as a HTMLString and would like to have a UIView that tells the UIWebview to scroll to an anchor link. Can I scroll to the anchor link from the already loaded HTML content or I would have to reload the page with the anchor link in the URL? thanks, fbr ...
Hi All, I am trying to save a rotated and scaled UIImageView as an UIImage in the position and with the zoom scale that the user edited too. But I can only manage to save the original image as it was before editing. How can I save the image as it is shown in the UIImageView with the same scaling and rotation? I have read that I need to u...
I want to organize somehow my iPhone game's level-views, but I simply cannot (without expanding Object Allocations). I made a really "skeleton" of my code (this game has 2 levels, the goal is to release the iPhone display). I just cannot dealloc the previous level, so Instrunments shows incrementing BGTangramLevel instances. Please, tak...
