Question

我使用图像选择器控制器来呈现相机，拍摄完图像后，它进入结束模式，所以我希望代表在相机完成拍摄时调用。就像通过NSNotificationCenter一样。

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

Answer 1

试试这个：

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

Answer 2

在拍照后调用了UIImagePickerController .it的委托方法。

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

如何知道相机完成拍照在ios中
