Question

当我使用UIimagepicker控制器调用相机时，它在iOS版本4.2的iPhone上不会以全屏模式显示，但它在iOS 5中可以正常工作。

有人能告诉我需要更改的代码以及现有代码的问题是什么？

我使用以下代码：

    - (IBAction)takePicture:(id)sender 
{

    UIImagePickerController* imagePicker = [[UIImagePickerController alloc] init];

    imagePicker.delegate = self;
    imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePicker.showsCameraControls = YES;
    imagePicker.allowsEditing = NO;
    imagePicker.toolbarHidden = YES;
    imagePicker.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    imagePicker.wantsFullScreenLayout = YES;

    if ([UIImagePickerController respondsToSelector:@selector(isCameraDeviceAvailable:)])
    {
        if ([UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront])
        {
            [imagePicker setCameraDevice:UIImagePickerControllerCameraDeviceFront];


        }
    }

    // Show the camera UI and View Finder.

    [self presentModalViewController:imagePicker animated:YES];
    [imagePicker release];
}

其中一个解决方案是应用缩放转换 - here on stack也许它会有所帮助

我不明白你为什么要做这三件事：

[self.navigationController setNavigationBarHidden:YES];
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];
[self.camPicker.view setUserInteractionEnabled:YES];

或者就此而言，为什么要缓存UIImagePickerController的实例（与使用之间丢弃图像选择器控制器相比，这可能会导致应用程序的空闲内存使用量显着增加）。如果你不做这些事情会更好吗？

UIImagepickerController没有在iPhone 4.2的全视图中显示相机
