Programmatically send to front/back elements created from interface builder
cocoa-touch, interface-builder, z-axis
Solution
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.
Problem
In interface builder, there are layout 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 update the z-axis.
