You can get the device model number using uname from sys/utsname.h. For example: #import <sys/utsname.h> NSString* machineName() { struct utsname systemInfo; uname(&systemInfo); return [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding]; } The result should be: @”i386″ on the simulator @”iPod1,1″ on iPod Touch @”iPod2,1″ on iPod Touch Second Generation @”iPod3,1″ on iPod Touch Third Generation @”iPod4,1″ on iPod Touch … Read more

There are quite a few ways to check if a device is an iPad. This is my favorite way to check whether the device is in fact an iPad: if ( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad ) { return YES; /* Device is iPad */ } The way I use it #define IDIOM UI_USER_INTERFACE_IDIOM() #define IPAD UIUserInterfaceIdiomPad … Read more

Use the auto-resizing capabilities of iOS, so your views can adjust, and adapt any screen size. That’s not very hard, read some documentation about that. It will save you a lot of time. … Read more
