Programmatically send front / back elements created from an interface builder

Question

There are layout options in the interface designer for sending back or sending to the forefront any elements such as UIButton , UIImage , UILabel , etc.

Now, I would like to do the same at runtime, programmatically.

Is there an easy way to do this?

I do not want to create different views, just updating the z-axis.

Answer 1

There are several UIView methods that allow you to change the hierarchy of views.

• bringSubviewToFront:
• sendSubviewToBack:
• insertSubview:atIndex:
• insertSubview:aboveSubview:
• insertSubview:belowSubview:
• exchangeSubviewAtIndex:withSubviewAtIndex:

Since your views are already inserted into your supervisor, you can easily call bringSubviewToFront: once for each view in any order.

Answer 2

You can use:

 [self.view bringSubviewToFront:myButton];
