Question

我正在尝试创建一个自定义的alertview类，但是我在为视图点击创建完成块时遇到问题

我想要的是这样的，

+ (void)alertview:(UIViewController*)vc handler:(void (^)(UITapGestureRecognizer *))callback{
    UILabel *lbl1 = [[UILabel alloc] init];
    lbl1.text = @"A";
    UILabel *lbl2 = [[UILabel alloc] init];
    lbl1.text = @"B";
    UILabel *lbl3 = [[UILabel alloc] init];
    lbl1.text = @"C";
}

当用户触摸时，例如，lbl2

[RFAlertView alertview:self handler:^(UITapGestureRecognizer *selected){
                    NSLog(@"selected label is : %@",selected);
                }];

检查您的UILable UserIneteractionEnabled是否设置为YES

创建alertview并点击标签
