564NSData to NSString and vice versa

From NSData to NSString: 
NSString *s = [[NSString alloc] initWithData:d encoding:NSUTF8StringEncoding];
And the other way round: 
NSData *d = [s dataUsingEncoding:NSUTF8StringEncoding]:

33CGPointMake

CGPoint CGPointMake ( CGFloat x, CGFloat y ); x, y has to be floats, passing only integers might not work. especially good to know, when and if ints get converted into floats. = CGPointMake(100.0f + someIntVar, 50.0f + anotherIntVar); ≠ CGPointMake(100 + someIntVar, 50 + anotherIntVar); this .0f seems to have a meaning after all.
