UIView subviews' order?

Question

If i use a for loop;

for(UIView *subview in [myView subviews])

in which order, subviews are brought?

According to their added order or something else?

Answer 1

As the documentation says, it reflects their visible order in the screen.

@property(nonatomic, readonly, copy) NSArray *subviews

Discussion

You can use this property to retrieve the subviews associated with your custom view hierarchies. The order of the subviews in the array reflects their visible order on the screen, with the view at index 0 being the back-most view.

For complex views declared in UIKit and other system frameworks, any subviews of the view are generally considered private and subject to change at any time. Therefore, you should not attempt to retrieve or modify subviews for these types of system-supplied views. If you do, your code may break during a future system update.

Answer 2

I find it to be useful, and in my experience it places subviews in order that they were added. Just be careful using them when using UIScrollView. I occasionally ran into 'phantom' subviews that are created for scroll bars
