横向的 UIImagePickerController [英] UIImagePickerController in Landscape

问题描述

我一直在寻找这个问题的答案，但什么也想不出来.显然，iPhone SDK 3.0 使得 UIImagePickerController 可以以横向模式显示 - 但我没有找到任何允许这样做的方法.我认为如果应用程序默认处于横向模式，它会自动调整图像控制器，但这对我不起作用.

I have been searching for an answer to this, but cannot come up with anything. Apparently, iPhone SDK 3.0 made it possible that UIImagePickerController can be displayed in landscape mode - but I am not finding any method that will allow this. I would think that if the application is in landscape by default it would automatically adjust the image controller, but that is not working for me.

感谢您的帮助！

推荐答案

我还没有检查这是否非法，但它对我有用.如果您希望 UIImagePickerController 在横向代码中启动(并停留):

I haven't checked whether this is illegal, but it worked for me. If you want the UIImagePickerController to start(and stay) in Landscape orientation code:

//Initialize picker

UIImagePickerController * picker = [[UIImagePickerController alloc] init];
   picker.delegate = self;


//set Device to Landscape. This will give you a warning. I ignored it.
//warning: 'UIDevice' may not respond to '-setOrientation:'


[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];

//Set Notifications so that when user rotates phone, the orientation is reset to landscape.
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];

//Refer to the method didRotate:   
[[NSNotificationCenter defaultCenter] addObserver:self
              selector:@selector(didRotate:)
               name:@"UIDeviceOrientationDidChangeNotification" object:nil];

//Set the picker source as the camera   
picker.sourceType = UIImagePickerControllerSourceTypeCamera;

//Bring in the picker view   
[self presentModalViewController:picker animated:YES];

didRotate 方法:

The method didRotate:

- (void) didRotate:(NSNotification *)notification

{
      //Maintain the camera in Landscape orientation
 [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];

}
