useful macro function for objective-c

for get log with class name, method name and line no

 #define DLog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__)  

for get UIColor

 #define COLOR(r,g,b) [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:1]  

is device type iPad or iPhone

 #define IS_iPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)  
 #define IS_iPhone ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)  

is system iOS7 Or less

 #define IS_IOS7 (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1)  

is device have 4inches display

 #define IS_4INCHES_DEVICE( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )  

for comparing system version

 #define SYSTEM_VERSION_EQUAL_TO(v)         ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)  
 #define SYSTEM_VERSION_GREATER_THAN(v)       ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
