I found examples about creating a rect or round UIButton.

Is possible to create an UIButton with a particular shape (e.g. a heart, a star and so on)?

How?

Answer 1

The easiest way to accomplish that is using:

UIButton *myButton=[UIButton buttonWithType:UIButtonTypeCustom];
[myButton setFrame:CRectMake( 0, 0, imWidth, imHeight)];
[myButton setBackgroundImage:[UIImage imageNamed:@"shabadabada.png"] forState:UIControlStateNormal];

And that would get you a simple button ... though it is not actually shaped like a "shabadabada" (:P) it will be a squared button.

To do a truly custom shaped "button" you would have to implement from the UIView class:

-(void) drawRect:(CGRect)rect;

And you would have to draw your shape point by point, here's a simple guide on doing this.

And also respond to the following methods:

– touchesBegan:withEvent:
– touchesMoved:withEvent:
– touchesEnded:withEvent:
– touchesCancelled:withEvent:

Or just to:

– addGestureRecognizer:
