I'm writing an iPhone/iPad app, and I'm wondering if future updates will wipe the application's sandbox data (this is of vital importance for me since my app will use in app purchase). I've already googled around but couldn't find any definite answer. Thanks! ...
Partly as a programming exercise, and partly because we may need to include such images in an app some day, I've been trying to figure out how to draw an image like the selected tab in a UITabBar. The basic operation is simple enough in concept: the icon's alpha is used as a mask to draw the blue gradient image onto the tab. (Though I c...

I am going crazy - these 2 strings are identical but the code comes back as them being different!: NSLog(@"nearbyAirport %@", nearbyAirport.geocode); NSLog(@"airportToFind %@", airportToFind.geocode); //Try and match geocodes. If they are the same then airport is valid if ([[airportToFind geocode] isEqualToString:[nearbyAirport geocod...
Hello! Just I'm curious. I have created a lot of convinient categories to the Objective-C classes (NSObject, NSDictionary, NSString...), as long as very interesting subclasses that makes a lot of popular task in the iPhone/iPad programming, to be as easy as putting only one line of code or firing a method. I'd like to share this code w...

The user's image is 50x50, but I want a border around it so I set the view to center the image and set the frame to 52x52 and then set the background color of that view to my border color. That shows a 1 pixel border around the image. I also want to show...

I have understandably attracted some smart ass answers to some bone head questions I have asked lately due to my complete misunderstanding of obj c and NSMutable arrays. So I've looked in a book I have and Google and it would appear that may be I shouldn't program because I'm still stuck. Say I'm looping through method A and each loop ...
I'm in deep trouble. Something in my app causes a lot of properties in my app delegate to become trashed (changing contents and even object type, say an NSArray becomes an NSString...), and I can't debug it out. I can find no memory leaks or errors on my part. The only thing I've found is that all the way to ViewDidAppear for the view of...
Can't figure it out Thanks. ...
I'm trying to do some simple assignment, but coming up with different results and I can't figure out why. Why does the first assignment below work and the second one not?
