将子视图添加到UIButton

Question

我正在尝试添加一个customBadge作为UIButton的子视图 -

到目前为止这是我的代码 -

//msg count initiaition
//CustomBadge *customBadge1 = [CustomBadge customBadgeWithString:@"2"];
CustomBadge *customBadge1 = [CustomBadge customBadgeWithString:@"2"
                                               withStringColor:[UIColor whiteColor]
                                                withInsetColor:[UIColor redColor]
                                                withBadgeFrame:YES
                                           withBadgeFrameColor:[UIColor redColor]
                                                     withScale:2.0
                                                   withShining:YES];

    // Set Position of Badge 1
[customBadge1 setFrame:CGRectMake(self.view.frame.size.width/2-customBadge1.frame.size.width/2+_MsgHeadBtn.frame.size.width/2, 110, customBadge1.frame.size.width, customBadge1.frame.size.height)];
 //add badge to view
[_MsgHeadBtn addSubview:customBadge1];

我正在尝试添加子视图的按钮是_MsgHeadBtn，这是下面屏幕截图顶部LH上的电子邮件图标。 我试图让自定义徽章在电子邮件图标的上方和右侧略微显示 - 但我最终得到了屏幕截图中的结果！

任何人都可以提出任何关于我哪里出错的建议！？

Answer 1

问题在您的setFrame:方法范围内。您正在使用self.view.frame.size.width。

检查此代码：

[customBadge1 setCenter:CGPointMake(_MsgHeadBtn.frame.size.width, 0)];
[_MsgHeadBtn addSubview:customBadge1];

或

[customBadge1 setFrame:CGRectMake(_MsgHeadBtn.frame.size.width, 0, customBadge1.frame.size.width, customBadge1.frame.size.height)];
[_MsgHeadBtn addSubview:customBadge1];

调整框架如下：

[customBadge1 setFrame:CGRectMake(_MsgHeadBtn.frame.size.width-customBadge1.frame.size.width,-customBadge1.frame.size.height/2, customBadge1.frame.size.width, customBadge1.frame.size.height)];
