Objective c UIActionView箭头位置iPad

我试图创建一个下拉菜单，我正在试验一个UIActionSheet。显示行动表时，是否有方法更改箭头的位置

UIActionSheet *actionSheet = [[UIActionSheet alloc]
                              initWithTitle:nil
                              delegate:self
                              cancelButtonTitle:nil
                              destructiveButtonTitle:nil
                              otherButtonTitles:nil];

[actionSheet addButtonWithTitle:@"Mr"];
[actionSheet addButtonWithTitle:@"Mrs"];
[actionSheet addButtonWithTitle:@"Miss"];

[actionSheet showFromRect:[sender frame] inView:self.view animated:YES];

简而言之，答案是否定的

对于该功能，您需要创建自己的UIActionSheet替代方案
