Detecting The iPhone Device Type

I’m having an issue when I deploy my app my phone. I am currently building the app on a 3gs, when the view is displayed, it is the iPhone 5 layout that shows, which makes some objects display partially off of the screen.

You can use the [UIDevice currentDevice] class method. This will donate you information approximately the device like systemName, systemVersion, model, etc.

If you need to obtain the screen dimensions instead, you could use the [UIScreen mainScreen] class method. With it you could obtain the applicationFrame or the screen bounds.

Hope this helps!
