what is the use of NSMakeRange in objective c? -

-

I am new to objective C and most of the time I am using NSR in my code. I have come to know that 'NSMKRange' is why, I want to know what is the use of NSMKRange.

This is a feature inline function, it's NSRange structure , returns it by populating it:

(to .. ./foundation.framework/Headers/ NSRange.h )

NS_INLINE NSRange NSMakeRange (NSUInteger loc, NSUInteger Lane) {NSRange r; R.location = loc; R.length = len; Return r; }

This makes it easy to create categories; Compare: 

  unichar buffer [8]; [SomeString getCharacters: Buffer Range: NSMKrange (2, 8)];

From: 

  unichar buffer [8]; NSRange category = {2, 8}; [SomeString getCharacters: Buffer Range: Category];

When pressed == is true, it means that the user is touching the screen: processed (fuel) processed () if life & gt; 0 and pressed == true remains = life - life 1 Life = life =. Wide-1 remains Value.text = string.format ("% d", life) End of this This function is active as the entrance event: runtime: addEventListener ( "Antrfrem" fuel Snsadna) it is very well, but my question is: pressed variable each time 5 seconds (once = = True) How is it possible to reduce the vitality width? I tried to add it to my touch even...
