我在UIPopoverController中使用UIImagePickerController,它与iOS6完美配合.使用iOS 7时,显示捕获图像的"预览"图像会旋转,但如果我拍照,则会正确保存.
这就是我选择的方式:
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObjects:
(NSString *) kUTTypeImage,
nil];
imagePicker.allowsEditing = NO;

并将其添加到弹出控制器:
self.imagePickerPopOver = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
[self.imagePickerPopOver presentPopoverFromRect:CGRectMake(aPosViewA.x, cameraButton_y, 100.0, 30.0) inView:self.detailViewController.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

这些是UIScrollView上按钮位置的计算,以显示正确位置的弹出窗口:
presentPopoverFromRect:CGRectMake(aPosViewA.x, cameraButton_y, 100.0, 30.0)

我不认为问题就在那里,因为我尝试了几种组合.
我还尝试在全屏模式下捕获图像,但应用程序只允许使用横向模式.如果以纵向模式拍摄图像并且取消模态视图,则应用程序也将保持纵向模式.如果模态视图被解除,我找不到阻止UIImagePickerController切换到纵向模式或强制应用程序回到横向模式的方法.
UPDATE
我从这里得到了答案,又向前迈进了一步.
我在创建选择器之后和显示弹出窗口之前转换视图:
switch ([UIApplication sharedApplication].statusBarOrientation) {
case UIInterfaceOrientationLandscapeLeft:
self.imagePicker.view.transform = CGAffineTransformMakeRotation(M_PI/2);
break;
case UIInterfaceOrientationLandscapeRight:
self.imagePicker.view.transform = CGAffineTransformMakeRotation(-M_PI/2);
break;
default:
break;
}

只要我不转动iPad,它就能正常工作.为此,我正在注册方向更改事件:
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil];
