I'm having my first foray into Cocoa Touch programming (and one of my first into Cocoa in general) and writing a simple game for the iPhone, though this question is about cocoa touch in general. The main UI consists of a strip of identical acting buttons (only varying in colour) arranged horizontally across the screen. Although they act...

There are labels with values associated with them. The difference is, I am making custom UITableViewCell nibs so that the "value" can be a textbox, segmented cont...
What's the simplest way to have a scroll view (with pagingEnabled set to YES) have a page width set to something other than the scroll view's bounds? Let me give an example. Suppose I have a scroll view with 10 items, each 150 pixels wide, and my scroll view is 300 pixels wide. If I start with views 1 and 2 visible and scroll horizontal...

From an MKCoordinateRegion, how do I tell what the top of a mapview's visible area is? The MKCoordinateRegion will have a center point (coordinates). Do I then add the latitudeDelta to the center point latitude to find the top of the map? Or must the delta be split in half and each half added and subtracted against the center point la...

Hi all! I'm developing a game in which I've imageviews for bow and arrow. I actually wanted to move this arrow along a circular path when set in the air. Specifically, this circular path should be the one which an object will travel when thrown in the air at a distance i.e. it'll move upwards first and then downwards. I've already trie...

I'm having a problem getting my view to be sized properly when created via -loadView. It seems that my view frame is always (0, 0, 320, 460), even when the view/controller is nested inside a UINavigationController and/or UITabBarController. Is there a way to detect programmatically when my view controller is nested within these items, ...

I created a class that wraps a UITextView and adds some ui elements. I want the new class' API to be identical with UITextView, so I use message forwarding (listing below) to relay messages between the wrapped text view and the delegate. The irritating thing is that the compiler issues warnings for method invocations on instances of my ...
I'm trying to sum the integers from five UITextFields and post them to a UILabel. This is the code I have tried, but it doesn't work properly. The number that shows up in the label is not the sum of my textfields. I have also tried to post to a textfield instead of a label, with the same result. No errors or warnings when I build. int ...
The following code deletes a core data object if the user did not end up modifying the new entry (this happens on an insert operation). The root view controller created the entity and passed a reference to my view. It works fine if the user hits a "done" button on my view, but if instead they navigate backwards using the "back" button on...
