UIWindow *win = [UIApplication sharedApplication].windows.firstObject;
[win addSubview:rightItem];

用[UIApplication sharedApplication].keyWindow试试。你说的不起作用也许是你没看见，可以用Debug的Capture View Hierarchy看看是否被挡住了

UIWindow *win = [UIApplication sharedApplication].windows.firstObject;是最下面的一个窗口。[UIApplication sharedApplication].windows.lastObjec才是界面最前面的窗口。
