Log in to like this post! iOS Tips and Tricks - Detecting Device and OS Stephen Zaharuk / Wednesday, October 9, 2013 When writing iOS apps it sometimes becomes necessary to detect what device or OS you're application is currently running on. In this post i'll give you quick access to snippets to do just that. Device Detection iPad BOOL iPad = ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad); iPhone BOOL iPhone = ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone); iPhone 5 (4" screen) BOOL iPhone5 = ([ [ UIScreen mainScreen ] bounds ].size.height >= 568 ); Retina Display BOOL retina = ([UIScreen mainScreen].scale >= 2); OS Detection iOS 7 BOOL iOS7 = (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1); It's worth noting that you can also detect the OS by validating against API that you know only exists in a specific version of the OS: BOOL iOS7 = NSClassFromString(@"UIInterpolatingMotionEffect") != nil; Enjoy!
