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