Xcode’s Interface Builder requires that you implement both or neither initializers for @IBDesignable classes to render properly in IB. If you implement required init(coder aDecoder: NSCoder) you’ll need to override init(frame: CGRect) as well, otherwise “the agent will crash” as seen in the errors thrown by Xcode. To do so add the following code to … Read more
Xcode 8+, iOS 10+ I recently faced this problem and none of the posted answers did it.

Don’t use UIControlEventValueChanged for UITextField. What you want is UIControlEventEditingChanged.
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.
[EDIT – this code is a bit moldy being from 2011 and all but I incorporated @ArtOfWarefare’s mods] You can’t do this w/ UIImageView. I created a simple UIView subclass MyImageView that contains a UIImageView. Code below. // MyImageView.h #import <UIKit/UIKit.h> @interface MyImageView : UIView { UIImageView *_imageView; } @property (nonatomic, assign) UIImage *image; @end … Read more
