How can I loop through all subviews of a UIView, and their subviews and their subviews?

Answer 1

Use recursion:

// UIView+HierarchyLogging.h @interface UIView (ViewHierarchyLogging) - (void)logViewHierarchy; @end  // UIView+HierarchyLogging.m @implementation UIView (ViewHierarchyLogging) - (void)logViewHierarchy {     NSLog(@"%@", self);     for (UIView *subview in self.subviews)     {         [subview logViewHierarchy];     } } @end  // In your implementation [myView logViewHierarchy];
