iOS UIActionSheet在7.1和8.3之间的不同

iOS7.1版本中：使用UIActionsheet显示在当前view时会触发当前view的 ViewWillLayoutSubViews

8.3中不会触发自动布局

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
                                                             delegate:self
                                                    cancelButtonTitle:@"cancel"
                                               destructiveButtonTitle:nil
                                                    otherButtonTitles:@"single article", @"serial article", nil
                                  ];
    actionSheet.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
    
    [actionSheet showInView:self.view];

特此小记一下
