Affecting Z Order for UIImageView

Hi,

Anyone know how to programmatically set the z order of UIImageViews? The order of instancing them will bring the last one instanced closest to the screen front, but how can it be changed at runtime?

Thanks // :)

+5 A:

You can use the following if the UIImageView is already a subview:

bringSubviewToFront
sendSubviewToBack

or any of the following if you're inserting the UIImageView as a subview:

insertSubview:atIndex
insertSubview:aboveSubview
insertSubview:belowSubview

Note that these methods are all defined on UIView, so you can use them on any kind of view, not just UIImageViews.

What if you have been adding the views with initWithParent rather than using subviews? Does initWithParent create subviews owned by the parent and kept in an index?

never heard of initWithParent but yes, you can access them with whatever.subviews

There is also exchangeSubviewAtIndex:withSubviewAtIndex:If CiNN's answer is good enough, why don't you select it as the answer? It helps to know what questions are in need of an answer and which aren't.
