              -(IBAction)savePrint{
//Save image to iOS Photo Library

                 UIImageWriteToSavedPhotosAlbum(imageDoodle.image, nil, nil, nil);
//Create message to explain image is saved to Photos app library
                 UIAlertView *savedAlert = [[UIAlertView alloc] initWithTitle:@"Saved"  

                message:@"Your picture has been saved to the photo library, view it in the 

               Photos app." delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
//Display message alert
             [savedAlert show];
              }`

Answer 1

尝试将shouldAutoRotate设置为NO,看看它是否有效.

您可以在iOS 6.0或更高版本中使用shouldAutoRotate和supportedInterfaceOrientations方法,而不是(不推荐使用)shouldAutoRotateToInterfaceOrientation方法.

像这样的东西 -

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskAll;
}


- (BOOL) shouldAutorotate {
    return YES;
}


- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return UIInterfaceOrientationPortrait;
}

Answer 2

您只支持有限的方向横向或纵向.但是你在视图控制器中调用了不同的方向.

您可以使用支持的方向查看以下图像.它只支持横向右侧和左侧景观.所以,如果我调用肖像,它将像您一样显示错误.因此,如果您想支持两种方向,请在摘要中更改它.

有关详细信息,请参阅此答案. 希望能帮助到你.

所以你必须把这个代码放在你的viewcontroller中

  - (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
  return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft |   UIInterfaceOrientationMaskLandscapeRight;
 }

Answer 3

如果plist中支持的接口方向与返回的接口方向不匹配,则会引发此错误 -(NSUInteger)supportedInterfaceOrientations

请记住,该NSUInteger返回的supportedInterfaceOrientations必须是UIInterfaceOrientationMask,注意-MASK-,我曾经做的只是返回UIInterfaceOrientation异的...面膜值的错误(这是自动完成你)

例如

- (NSUInteger) supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
    // and NOT UIInterfaceOrientationPortrait;
}
