iOS 获取view的controller UIView+UIViewController

标签：

直接上代码,简单易懂:

#import "UIView+UIViewController.h"

@implementation UIView (UIViewController)

- (UIViewController *)viewController {
   
    //通过响应者链，取得此视图所在的视图控制器
    UIResponder *next = self.nextResponder;
    do {
        
        //判断响应者对象是否是视图控制器类型
        if ([next isKindOfClass:[UIViewController class]]) {
            return (UIViewController *)next;
        }
        
        next = next.nextResponder;
        
    }while(next != nil);
    
    return nil;
}

@end
