iOS根据UIVIew获取当前的UIViewController

UIViewController *vc = [self getCurrentControllerByView:self needClassType:[UIViewController class]];

- (id)getCurrentControllerByView:(UIView *)view needClassType:(Class)needClassType { return [self traverseResponderChainForUIViewControllerByView:view needClassType:needClassType]; } - (id)traverseResponderChainForUIViewControllerByView:(UIView *)view needClassType:(Class)needClassType { id nextResponder = [view nextResponder]; if ([nextResponder isKindOfClass:needClassType]) { return nextResponder; } else if ([nextResponder isKindOfClass:[UIView class]]) { return [self traverseResponderChainForUIViewControllerByView:nextResponder needClassType:needClassType]; } else { return nil; } }
