Question

我开发了一个应用程序，从相机unitl拍摄照片这里所有很好的蝙蝠收到他的代表我解雇，我收到exc_bad_access这里是代码：

声明并打开相机：

-(void)ScattaFoto{
 UIImagePickerController *picke = [[UIImagePickerController alloc] init];
   // Delegate is self
   picke.delegate = self;

    // Allow editing of image ?
picke.allowsEditing=NO;


if(TARGET_IPHONE_SIMULATOR) {
      picke.sourceType =  UIImagePickerControllerSourceTypePhotoLibrary;
     }else{
    picke.sourceType =  UIImagePickerControllerSourceTypeCamera;
    }

   // Show image picker
[self presentModalViewController:picke animated:YES];

}

而不是委托事件：

- (void) imagePickerController:(UIImagePickerController *)picke   didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// Access the uncropped image from info dictionary
//UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

// [picker release];
[self  dismissModalViewControllerAnimated: YES]; // Here i receive exc_bad_access
[picke release];
}

我把.h引用了imagePickerControl的委托“UINavigationControllerDelegate，UIImagePickerControllerDelegate”

有人可以帮助我吗？

Answer 1

- (void) imagePickerController:(UIImagePickerController *)picke didFinishPickingMediaWithInfo:(NSDictionary *)info{
    [picke  dismissModalViewControllerAnimated: YES];
}

Answer 2

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo{
       [picker.presentingViewController dismissViewControllerAnimated:YES completion:nil];

}

Answer 3

也许ARC在调用didFinishPickingMediaWithInfo之前发布你的UIImagePickerController？

尝试将UIImagePickerController放在@property中，如下所示：

@property (nonatomic, strong) UIImagePickerController *picke;

You can read more about @properties here.

在使用之前，你仍然需要分配和初始化UIImagePickerController。
