How can I get the index of sub UIView in the parent view?

Question

I want to use exchangeSubviewAtIndex: withSubviewAtIndex: method.

but how can i get the indexes of those views? i already have their pointers, so I thought there might be a method like.

[parentView indexOfSubview:subview];

but I couldn't find that kind of thing in Xcode documents library.

please help me! thank you in advance.

This is how you get it:

[parentView.subviews indexOfObject:subview];

In Swift:

parentView.subviews.firstIndex(of: subview)

You can find out the index of your object as you find in NSArray, because view.subviews return an array

NSUInteger index1=[parentView.subviews indexOfSubview:subview1];
NSUInteger index2=[parentView.subviews indexOfSubview:subview2];

[parentView exchangeSubviewAtIndex:index1 withSubviewAtIndex:index2];

your code needs a bit of editing @Rajneesh... NSUInteger index1=[parentView.subviews indexOfObject:subview1]; NSUInteger index2=[parentView.subviews indexOfObject:subview2]; [parentView exchangeSubviewAtIndex:index1 withSubviewAtIndex:index2]; You'll note the indexOfSubview changes to indexOfObject and exchangeObjectAtIndex changes to exchangeSubviewAtIndex on the parentView – amergin Apr 19 '14 at 13:47

You can get array index using this.

[view.subViews indexOfObject:yourSubView];

And try to catch that index.

NSInteger index=[view.subViews indexOfObject:yourSubView];

Try this code might be helpful to you...
