I'm trying to let a player tap, drag and release a card from a fanned stack on the screen to a 4x4 field on the board. My cards are instantiated from a custom class that inherits from the UIImageView class. I started with the Touches sample app, and I modified the event handlers for touches to iterate over my player's card hand instead ...
Hi, I want to get amount of taps anywhere on the screen.

But it doesn't detect multiple taps - it reports me them as a single tap. How can I...

I've been trying out some of the view code from Erica Sadun's book "The iPhone Developer's Cookbook" and found some code I don't understand. Here's the code for a loadView method: - (void)loadView { // Create the main view UIView *contentView = [[UIView alloc] initWithFrame: [[UIScreen mainScreen] applicationFrame]]; contentView.b...
I finished building an app that allows beaming of photos, contacts and text clips over Wi-Fi IPhone to IPhone and IPhone to desktop. I want to decide on the feature set of the lite version of my IPhone app. I also want to come up with a pricing model. So the question is, which of these components should be free, and for which I should...

I have a bug I'm struggling to track down. I believe what's happening is that I'm deleting an object from the underlying database whilst another managed object context (in another thread) has a fault on it and gets the 'NSObjectInaccessibleException' when it tries to fulfil the fault. The scenario is that I have a view accessing the dat...

I'm a little ways into developing my first iphone app, and I've been running into exc_bad_access a lot. (I'm sure it's because I'm not designing stuff in a very MVC-proper way yet.) It's extremely frustrating trying to hunt down why I'm running into these errors all the time... is there a way in the xcode debugger to keep a watch list ...
