Question

I have a subclass of a UIButton.

Here’s the code I have to attempt to rotate it.

-(void)drawRect:(CGRect)rect {

    CGContextRef context = UIGraphicsGetCurrentContext();

    CGFloat angle = (-126.0 * M_PI) / 180.0;
    CGContextRotateCTM(context, angle);
}

But, nothing’s happening. The view draws to the screen in its default orientation. Any idea what I’m missing? Thanks!

Normally when you want to rotate a button, you don’t do it by subclassing and modifying drawRect.

All you have to do is:

button.transform = CGAffineTransformMakeRotation(M_PI/2);
