Question

Im using image picker controller to present Camera,After image has been taken it's entering into ending mode, So i want the delegate to call when camera is completed taking picture. Like by means of NSNotificationCenter .

       UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate=self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    [self presentViewController:picker animated:YES completion:NULL];

Answer 1

尝试这个：

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

Answer 2

UIImagePickerController有一个委托方法。拍照后被调用。

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