Adding a subview to UIButton

问题

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

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];

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!

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

回答1:

Issue is within your setFrame: method. You are using self.view.frame.size.width.

Check with this code:

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

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

回答2:

Adjust your frame like below:

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