I did not write this, I found it on Stack Overflow attributed to user Sophtware. Finding it useful, I decided to save this here, in case SO deleted the page (since the question was closed as a non-question)
***************************************************************************************************

void dumpViews(UIView* view, NSString *text, NSString *indent) 
{
    Class cl = [view class];
    NSString *classDescription = [cl description];
    while ([cl superclass]) 
    {
        cl = [cl superclass];
        classDescription = [classDescription stringByAppendingFormat:@":%@", [cl description]];
    }

    if ([text compare:@""] == NSOrderedSame)
        NSLog(@"%@ %@", classDescription, NSStringFromCGRect(view.frame));
    else
        NSLog(@"%@ %@ %@", text, classDescription, NSStringFromCGRect(view.frame));

    for (NSUInteger i = 0; i < [view.subviews count]; i++)
    {
        UIView *subView = [view.subviews objectAtIndex:i];
        NSString *newIndent = [[NSString alloc] initWithFormat:@"  %@", indent];
        NSString *msg = [[NSString alloc] initWithFormat:@"%@%d:", newIndent, i];
        dumpViews(subView, msg, newIndent);
        [msg release];
        [newIndent release];
    }
}

How to Use
***************************************************************************************************
To dump the entire view hierarchy of your application, call the method like this:

dumpViews([[UIApplication sharedApplication] keyWindow], @"", @"");

To display the hierarchy of the the camera view, override this method in your controller:

navigationController:willShowViewController:viewController:animated

and call the dump routine like this:

dumpViews(self.modalViewController.view, @"", @"");

For all other views:

dumpViews(myView, @"", @"");
