iOS 7：在UIActionSheet委托功能中创建的UIAlertView无法自动旋转 [英] iOS 7: UIAlertView created in UIActionSheet delegate function cannot auto rotate

问题描述

该问题只能在iOS 7中重现。

The issue only can be reproduced in iOS 7.

在委托函数中： - （void）actionSheet：（UIActionSheet *）actionSheet clickedButtonAtIndex：（NSInteger）buttonIndex ，如果创建了UIAlertView，则警报视图无法自动旋转。以下是示例代码：

In the delegate function:- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex, if a UIAlertView is created, the alert view cannot auto rotate. Here is the sample code:

- (IBAction)buttonTapped:(id)sender
{
    UIActionSheet *actionSheet = [[UIActionSheet alloc]
                                  initWithTitle:@"action sheet"
                                  delegate:self
                                  cancelButtonTitle:@"cancel"
                                  destructiveButtonTitle:@"ok"
                                  otherButtonTitles:nil];
    [actionSheet showInView:self.view];
}

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    UIAlertView *alert = [[UIAlertView alloc]
                          initWithTitle:@"alert"
                          message:nil
                          delegate:self
                          cancelButtonTitle:@"ok"
                          otherButtonTitles:nil];
    [alert show];
}

这是iOS 7的错误吗？如果是，是否有任何方法可以使警报视图与屏幕中的其他视图一起自动旋转？

Is this a bug of iOS 7? If yes, is there any way to make the alert view auto rotate with the other view in the screen?

推荐答案

尝试展示来自UIActionSheet的另一个委托方法的alertview。这确实有效：

Try presenting the alertview from another delegate method of UIActionSheet. This does work:

- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex

这肯定看起来像是iOS7中的错误:)

This surely looks like a bug in iOS7 :)
