NSLog with CGPoint data

Question

I have a CGPoint called point that is being assigned a touch:

UITouch *touch = [touches anyObject];

CGPoint point = [touch locationInView:self];


        

Answer 1

NSLog(@"point x,y: %f,%f", point.x, point.y);

Answer 2

Actually, the real easiest way to log a CGPoint is:

NSLog(@"%@", NSStringFromCGPoint(point));

The desktop Cocoa equivalent is NSStringFromPoint().

Answer 3

point.x is a floating point number so you should code like this:

NSLog(@"%@",[NSString StringWithFormat:@"%f",point.x]);

Answer 4

The simplest way to log a CGPoint value is to use the NSValue class, since it will give you all the relevant values formatted nicely for the console. It's done like so:

NSLog(@"myPoint = %@", [NSValue valueWithCGPoint:myPoint]);

You can also use the +valueWithCGRect and +valueWithCGSize methods of NSValue when you're trying to log, say, the frame (CGRect) or size (CGSize) properties of a UIView.

Answer 5

use :

NSLog(@"%@", NSStringFromCGPoint(point));

You can also use NSString for following info :

NSStringFromCGPoint
NSStringFromCGSize
NSStringFromCGRect
NSStringFromCGAffineTransform
NSStringFromUIEdgeInsets

Answer 6

point.x is a floating point number, so you should use:

NSLog(@"x: %f", point.x);
