Assembled elders of the Cocoa-Touch, I have a question for you all about Drag & Drop on the iPad. I am attempting to drag an item from a popover onto an underlying canvas. Employing the UIPanGestureRecognizer class I can detect a drag-start and create a UIView to drag with the finger tip. My application runs in landscape mode. The tro...

I'd like to take a UITextView and allow the user to enter text into it and then trigger a copy of the contents onto a quartz bitmap context. Does anyone know how I can perform this copy action?

I use the block base API for my animations on iOS. One animation has a completion block and that block is called at the end of the animation, nice. However, that animation can be fired multiple times when the user scrolls (the animation is on a UITableViewCell). When that happens the the completion block is called multiple times. The ...
Here's what I need to do: I will have a toolbar with multiple objects on it (for this we'll call them A,B,C,D) and I want to be able to have the user click and drag them around and be able to snap them to a grid and connect to each other. Sounds easy, right? Well here's my problem: some objects are different sizes, so A could be a 1x1...

Thus, when rotation occurs, in willRotateToInterfaceOrientation i call [self.view setNeedsLayout]; and my layoutSubviews method is as follows: - (void)layoutSubviews { NSLog(@"here in layoutSubviews"); }...

Is there an easy way of finding out a view's frame as it appears in the context of the screen? Or do I just need to do a subtraction between the UIBut...
Hi all, I have a UIView that can be dragged with the finger which I've implemented by using a UIPanGestureRecognizer. This allows me to drag a view horizontally ; left or right. I make my view moving while receiving the following state from the UIPanGestureRecognizer (using the translationInView: method): UIGestureRecognizerStateBega...
