iPhone：移动没有 Animation 的 UIButton

Question

There are boatloads of hits on animating a UIButton move. I want to do the opposite - move the button without animation. Is it possible to move a button created in interface builder without animations? If so, would someone mind sharing the method as there is no setPosition message.

Answer 1

You will need an outlet for the button and you can use either frame , center or transform to move the button.

button.frame = newFrame; // where `newFrame` is the frame to move to.
button.center = newCenter; // where `newCenter` is a CGPoint 
button.transform = CGAffineTransformMakeTranslation( xDisplacement, yDisplacement);

Here transform doesn't change the center or the frame but only moves the button.

Answer 2

Yes, try to use setFrame: [button setFrame:CGRectMake(newX, newY, newWidth, newHeight)];

Answer 3

How about setting different frame? you can move the button by setting different frame to it.
