HI, I have Parentview-->Multiple childviews. when i use [self bringSubviewToFront:childview] in parentview, it works fine.but after adding grandchildview to childview,when i use [self bringSubviewToFront: grandchildview] in parentview, it did not work?any help please?
The -[UIView bringSubviewToFront:]
method only works for direct children, not grandchildren. Remember that the view hierarchy is a tree, and normally a view only knows about its "parent" (or superview) and its direct "children" (or subviews). You would need to do something like this:
// First, get the view embedding the grandchildview to front.
[self bringSubviewToFront:[grandchildview superview]];
// Now, inside that container view, get the "grandchildview" to front.
[[grandchildview superview] bringSubviewToFront:grandchildview];
my contribution with the swift version from the checked solution
self.bringSubviewToFront(self.grandchildview.superview!)
self.grandchildview.superview!.bringSubviewToFront(self.grandchildview)
