How to put UIImageView on the background of the layout

问题

Greetz,

So this is rather a simple question (maybe not a simple answer). I want the IB option called 'send to back' (On IB, go to Layout -> Send to back) to be done programmatically.

Is it possible? If not, any suggestions to simulate the same thing?

This is for an UIImageView as the title states.

回答1:

Use sendSubviewToBack:

[yourSubView.superview sendSubviewToBack:yourSubView];

回答2:

[self insertSubview:view atIndex:index];

Just experiment with the index you need.
