ios6中的UIImagePickerController追赶

Question

当我在ios 6中触摸我的拍照按钮时，我的应用程序崩溃了，我真的不知道如何解决它...（im n00b）:)

看一下我的代码Buttons.h：

 @interface Buttons : UIViewController
    <UIImagePickerControllerDelegate,
    UINavigationControllerDelegate>

    @property BOOL newMedia;
    @property (strong, nonatomic) IBOutlet UIImageView *imageView;
    - (IBAction)useCamera:(id)sender;
    - (IBAction)useCameraRoll:(id)sender;
    @end

Buttons.m :

#import "Buttons.h"




 @implementation Buttons

    - (void) useCamera:(id)sender
    {
        if ([UIImagePickerController isSourceTypeAvailable:
             UIImagePickerControllerSourceTypeCamera])
        {
            UIImagePickerController *imagePicker =
            [[UIImagePickerController alloc] init];
            imagePicker.delegate = self;
            imagePicker.sourceType =
            UIImagePickerControllerSourceTypeCamera;
            imagePicker.mediaTypes = @[(NSString *) kUTTypeImage];
            imagePicker.allowsEditing = NO;
            [self presentViewController:imagePicker
                               animated:YES completion:nil];

        }
    }
    #pragma mark -
    #pragma mark UIImagePickerControllerDelegate

    -(void)imagePickerController:(UIImagePickerController *)picker
    didFinishPickingMediaWithInfo:(NSDictionary *)info
    {


        [self dismissViewControllerAnimated:YES completion:nil];




    }

    -(void)image:(UIImage *)image
    finishedSavingWithError:(NSError *)error
     contextInfo:(void *)contextInfo
    {
        if (error) {
            UIAlertView *alert = [[UIAlertView alloc]
                                  initWithTitle: @"Save failed"
                                  message: @"Failed to save image"
                                  delegate: nil
                                  cancelButtonTitle:@"OK"
                                  otherButtonTitles:nil];
            [alert show];
        }
    }
    -(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
    {
        [self dismissViewControllerAnimated:YES completion:nil];
    }
    @end

    @implementation UIImagePickerController (NonRotating)

    - (BOOL)shouldAutorotate
    {
        return NO;
    }

    - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
    {
        return UIInterfaceOrientationMaskPortrait;
    }

    - (NSUInteger)supportedInterfaceOrientations
    {
        return UIInterfaceOrientationMaskAll;
    }
    @end

抱歉，如果我太无法处理:)如果有人可以阅读我的代码，并解决我的小问题...我将是世界上最幸福的人...

尝试按下面的按钮操作并检查：

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

imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;

imagePicker.delegate = self;

[self presentViewController:imagePicker animated:YES completion:nil];
