• (MBProgressHUD )HUDForView:(UIView )view { NSEnumerator subviewsEnum = [view.subviews reverseObjectEnumerator]; for (UIView subview in subviewsEnum) { if ([subview isKindOfClass:self]) { return (MBProgressHUD *)subview; } } return nil; }

in this line afte assertion failure: NSEnumerator *subviewsEnum = [view.subviews reverseObjectEnumerator];

MBProgressHUD needs to be accessed on the main thread.

This means that you are using HUD methods that are meant to be accessed on the main thread on a different thread. That's likely an issue in your code. Check your threading code.
