需求：

点击父View做一件事，点击子View做另一件事

如果这个子View恰巧是一个UIImageView

方式：

UIImageView *AutoCode = [[UIImageView alloc] init];

AutoCode.image = [UIImage imageNamed:@"getPassCodeNew"];

[AutoCode setFrame:CGRectMake(10, 200, self.view.frame.size.width - 20, 200)];

AutoCode.userInteractionEnabled = YES;

UITapGestureRecognizer *tapImage = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(_loginAction)];

[AutoCode addGestureRecognizer:tapImage];

[scrollView addSubview:AutoCode];

同时父View也注册一个手势

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapGestureRecognizer:)];

//    tap.numberOfTapsRequired = 1;

[self.view addGestureRecognizer:tap];

子View的成功不响应他爹的事件，而是专心响应自己的事件了 -。-。

简书看起来不错，所以以后记录问题什么的都搬到这来了0.0.
