向 UIButton 添加子视图

Adding a subview to UIButton(向 UIButton 添加子视图)

问题描述

我正在尝试将 customBadge 添加为 UIButton 的子视图 -

I'm trying to add a customBadge as a subview of a UIButton -

这是我目前的代码 -

this is my code so far -

//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];

我要添加子视图的按钮是 _MsgHeadBtn，它是下面屏幕截图左上方的电子邮件图标.我试图让自定义徽章略微显示在电子邮件图标的上方和右侧 - 但我最终得到了屏幕截图中的结果！

The button I'm trying to add the subview to is _MsgHeadBtn, which is the email icon on top LH of the screenshot below. I was trying to make the custom badge appear slighty above and to the right of the email icon - but I end up with the result in the screenshot!

谁能提供任何关于我哪里出错的建议！?

Can anyone offer any advice as to where i'm going wrong!?

推荐答案

问题出在您的 setFrame: 方法中.您正在使用 self.view.frame.size.width.

Issue is within your setFrame: method. You are using 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];
