Problems Converting CGPoint to String

Question

I'm having trouble converting CGPoint to string. I tried various methods, but it seems the most promising, but it still won't work. Any suggestions?

Here is my code:

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; coord = [touch locationInView:touch.view]; viewcoord.text = [NSString stringWithFormat:@"coordinates %@", coord.x, coord.y]; 

I get the output, but it just says "null" and I don’t understand why ...

thanks

Answer 1

 viewcoord.text = [NSString stringWithFormat:@"coordinates %@", NSStringFromCGPoint(coord)]; 

Answer 2

The format string uses %@ , which applies only to objective-C objects. It looks like you are trying to print not one, but two values ​​(x and y), both of which are floats. Try the following:

 viewcoord.text = [NSString stringWithFormat:@"coordinates %f, %f", coord.x, coord.y];
