I populate view controllers 1 and 2 using an NSXMLParser which gets called on viewWillAppear. In the forward (VC1 to VC2 to VC3) direction, ev...
The default settings for which information friends can share does NOT allow friends to grant an application access to "interested in and looking for" and "religions and political views". Most Facebook users have not changed these settings, meaning that only the users that have explicitly allowed friends to share interested in informatio...

Hey! I need to find a way to keep my page's bounce scrolling looking good.

I'm running into a very annoying issue developing javascript for a UIWebView in an iPhone application. If there is an error in the javascript, it silently fails and halts execution of the function it was running. And some errors do not happen in a desktop browser, so all appears fine. I then run it on an iPhone and get a massive failu...

I want to be able to pass the geolocation coordinates to the map and have it center the location with a marker. What I'm getting now is the map at the proper zoom level but the desired center-point appears in the upper-righthand corner. ...
My class contains an UIImage property which I want to enforce as a 'copy' property by any external clients accessing it. But, when I try to do a copy in my custom setter, I get the runtime error about UIImage not supporting copyWithZone. So what's a good way to ensure that the correct ownership policy is followed? // declared in the int...

Instruments reports this a memory leak (98.6%, whatever that means): [[NSNotificationCenter defaultCenter] postNotificationName:kNotificationSomeNotification object:self]; "self" is a subclass of UIImageView.

When debugging crashes and errors, the NSLog() function is incredibly useful, even vital. Unfortunately, some errors can provoked by pushing an app to the background, and that same act 'cuts' the ability to receive NSLog info, which makes debugging crashes related to moving an app into the background very difficult. How can I get NSLog...

Hi, I have made a Tic Tac Toe game. Everything is working fine, except that when the game is finished I am unable to reset the view to it's original state (without popping the view of the navigation stack and popping a new one back on).
