To program for the iPhone, you need an iPhone. That's because you have to compile the final version of the app on the iPhone hardware. Do you also need an iPad when you program for the iPad? Or will an iPhone also do the job? ...

When running in the Simulator, if I click on the ad, after dismissing the ad screen, the UIImageView is pushed 20px down, leaving a gap between the status bar and UIImageView.

Currently iOS supports three different art sizes: art for the 480x320 original iPhone screen, art for the hi-res 960x640 iPhone 4 screen, and art for the 1024x768 iPad screen, which in my experience is usually not the same as for the hi-res screen because of the different demands placed upon the different aspect ratio of the screen. In ...
So, I'm pretty much a noob, and I'm pretty sure I'm missing something fundamental, but this is the last hurdle I need to overcome to finish my app. Basically, I have 2 custom classes, my custom ViewController, and something I'm just calling "Button" which is a camera overlay view with a segmented control on it. The segmented control has...

I know how to do that in code and build settings, but it's getting hard to find devices to test on--I've upgraded my phone and so have most of my friends. And the simulator with XCode 3.2 doesn't support simulatin...

I'm aware that to preserve memory usage, UITableViewCells are reused when scrolling. I have some custom UITableViewCells that have UITextFields in them. After text is inputted to the UITextField, and I scroll, that text is lost because of the cell reuse. How can I make this text persist through scrolls? I'm thinking I can store each c...

My app hit the app store today. I had a user submit a weird bug. I have a date picker that passes back a date that I store as a string in SQLite. I tested the app on the simulator, a 3G, a itouch, and an iPAD. On all of these, it works as expected. However, on this user's 3GS it adds a day to the date selected in the date picker. I...
