Question

I have this method which lets me translate the position of an object, animating its move in my iPhone app:

-(void)translatePositionForLabel:(UILabel *)label toFrame:(CGRect)newFrame
{
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.5];
    label.frame = newFrame;
    [UIView commitAnimations];
}

You can see this works for UILabels, but without having a duplicate of this method (just swapping the object for say UIButton) is there anyway I can adapt this method so I can pass any object with a frame? Rather than needing an individual method for each object type.

Answer 1

Both UILabel and UIButton have a common ancestor in UIView; try passing that in place of label (you only appear to modify the label’s frame property, which is defined in UIView).
