ipad公司的UIImagePickerController仅前摄像机

我具有应在设备上只使用前摄像机iPad程序，ipad公司的UIImagePickerController仅前摄像机

的问题是，我走之后与前置摄像头的第一图片，如果用户选择重新拍摄一照片，然后使用后置摄像头，如果重新拍摄，则使用正确的前置摄像头，

我释放imagePicker和弹出窗口，显示我的相机预览和图像，每次拍摄图片时都会点击。

- (void)setUpImagePicker 
{ 
    //poner photo picker en pop up! 
    BOOL hasCamera = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]; 

    picker = [[UIImagePickerController alloc] init]; 
    picker.delegate = self; 
    picker.sourceType = hasCamera ? UIImagePickerControllerSourceTypeCamera : UIImagePickerControllerSourceTypePhotoLibrary; 
    picker.cameraDevice = UIImagePickerControllerCameraDeviceFront; 
    [picker setShowsCameraControls:FALSE]; 
    CGAffineTransform translate = CGAffineTransformMakeTranslation(0.0, 0.0); 
    picker.cameraViewTransform = translate; 
    CGAffineTransform scale = CGAffineTransformScale(translate, 1, 1); 
    picker.cameraViewTransform = scale; 

    self.companyPopOverController = [[[UIPopoverController alloc] initWithContentViewController:picker] autorelease]; 
    self.companyPopOverController.passthroughViews=[NSArray arrayWithObject:self.view]; 
    [self createTimer]; 
} 
- (NSTimer*)createTimer { 

    // create timer on run loop 
    return [NSTimer scheduledTimerWithTimeInterval:0.3 target:self selector:@selector(timerTicked:) userInfo:nil repeats:NO]; 
} 

- (void)timerTicked:(NSTimer*)timer { 

    [self.companyPopOverController presentPopoverFromRect:CGRectMake(622, 534, 10, 10) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES]; 
} 
- (void)takePicButtonPressed:(id)sender 
{ 
    NSLog(@"takePicButtonPressed"); 

    if (!self.retakePic) { 
     NSLog(@"retake no"); 
     self.retakePic = YES; 
     self.imageTaken = YES; 

     [self.takePicButton setImage:[UIImage imageNamed:@"takePicButton_Re"] forState:UIControlStateNormal]; 
     [picker takePicture]; 

     return; 
    }else { 
     NSLog(@"retake is yes"); 
     self.retakePic = NO; 
     self.imageTaken = NO; 

     picker = nil; 
     [picker release]; 
     self.companyPopOverController = nil; 
     [self.companyPopOverController release]; 
      [self setUpImagePicker]; 

     //button image, take 
     [self.takePicButton setImage:[UIImage imageNamed:@"takePicButton"] forState:UIControlStateNormal]; 

     return; 
    } 

}

那么我怎样才能确保我的应用程序只使用前置摄像头？

谢谢！

这是一个解决方法，但是因为没有代表你正在寻找的东西，所以这可以解决问题。

注册从PickerController在viewDidLoad中通知（在这种情况下，因为你实现你自己的控件，你可能要设置自己的通知）

[[NSNotificationCenter defaultCenter] addObserver:self 
             selector:@selector(retakeImage:) 
              name:@"_UIImagePickerControllerUserDidRejectItem" object:nil];

然后，当用户选择重拍照片再显捡拾工具使用前置摄像头。

- (void)retakeImage:(NSNotification *)notification 
    { 
     self.pickerController.cameraDevice = UIImagePickerControllerCameraDeviceFront; 
    }

希望这会有所帮助！
