“I’m just walking my beat friend. Mexico is my beat and I’m walking it…” (Johnny Depp / Once Upon a Time in Mexico)

In our case, UIViews are our beat, and we spend a lot of time walking them.

Here’s a simple function to recursively display all subviews within a parent view. It’s very convenient for finding out how many views are hidden within a parent view (such as UIImageViews, UILabels, UIButtons, etc.) — and it’s especially useful when debugging iPad apps with multiple levels of interactivity (such as scrollviews within scrollviews, or accordions within panels within scrollviews)…

- (void) dumpViews:(UIView *)theView withLevel:(int)theLevel {
	// this displays all views in the log
	// example usage:
	// NSLog (@"\r===================================\r===================================\r===================================\r");
	// [self dumpViews:self.view withLevel:0];
 

	for (int i = 0; i < [[theView subviews] count]; i++) {
		NSString *padding = @"";
		for (int n = 0; n < theLevel; n++) {
			padding = [NSString stringWithFormat:@"%@  ", padding];
		}
		if (theLevel)
			padding = [NSString stringWithFormat:@"%@-", padding];

		NSLog (@"%@%i : %@", padding, theLevel, [[[theView subviews] objectAtIndex:i] description]);
		[self dumpViews:[[theView subviews] objectAtIndex:i] withLevel:theLevel + 1];
	}
}
