UIDeviceHardware - Determine iOS device being used

readme.md

Some ways to use this class

NSString *platform = [UIDeviceHardware platform]; // to check the actual device model string
NSString *platformString = [UIDeviceHardware platformString]; // to check what this device is
UIDeviceType type = [UIDeviceHardware deviceType]; // to check the type
BOOL isThisAniPhone = [UIDeviceHardware deviceIsKindOfType:UIDeviceTypeiPhone]; // to check if this device is an iPhone
BOOL isThisNotASimulator = [UIDeviceHardware deviceIsKindOfType:~UIDeviceTypeSimulator]; // to check if the device is **not** a simulator (notice bitwise negation)
BOOL isThisAniPodOrAniPhone = [UIDeviceHardware deviceIsKindOfType:UIDeviceTypeiPhone|UIDeviceTypeiPod]; // to check if this device is an iPhone or an iPod (notice bitwise alternative)

Convenience methods

BOOL isThisAniPhone = [UIDeviceHardware deviceIsiPhone]; 
BOOL isThisAniPod = [UIDeviceHardware deviceIsiPod]; 
BOOL isThisAniPad = [UIDeviceHardware deviceIsiPad];
BOOL isThisASimulator = [UIDeviceHardware deviceIsSimulator];
