Question

I’ve been doing this, which works just fine, to see if my universal app is running on iPad or iPhone/iPad:

BOOL isIpad=[[UIScreen mainScreen] bounds].size.width<500?NO:YES

Any reason I should not based my test on the UIScreen bounds, or is there a better method?

Testing for the screen size is a very fragile test. Luckily, Apple already tells you what kind of device you’re running on.

For that, use the UI_USER_INTERFACE_IDIOM macro:

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    // Got an iPad.
} else {
    // == UIUserInterfaceIdiomPhone
    // Got an iPhone or iPod Touch.
}
