How to get UIView hierarchy index? (i.e. the depth in between the other subviews)

Question

From UIView docs:

(void)insertSubview:(UIView *)view atIndex:(NSInteger)index

It\'s great that I can insert a UIView at a certain index, bu

Answer 1

Set up a recursive method as follows:

- (void)printViewHierarchy:(UIView *)viewNode depth:(NSUInteger)depth
{
    for (UIView *v in viewNode.subviews)
    {
        NSLog(@"%@%@", [@"" stringByPaddingToLength:depth withString:@"|-" startingAtIndex:0], [v description]);
        if ([v.subviews count])
            [self printViewHierarchy:v depth:(depth + 2)]; // + 2 to make the output look correct with the stringPadding
    }
}

Then call it with:

[self printViewHierarchy:self.view depth:0];

Output:
