Programmatically send to front/back elements created from interface builder

Question

Hi,

In interface builder, there are layouts options to send to back or send to front 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 that?

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

Thank you.

Answer 1

There are a number of methods of UIView that allow you to modify the view hierarchy.

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

Since your views are already inserted into your superview, you could easily call bringSubviewToFront: once for each view in whatever order you like.

Answer 2

[self.view bringSubviewToFront:myButton];
