Question

我有一个像这样的UIImagePickerController：

    // Start picker code
    UIImagePickerController *photo = [[UIImagePickerController alloc] init];
    photo.delegate = self;
    photo.allowsEditing = NO;
    //photo.showsCameraControls = NO;
    photo.sourceType = UIImagePickerControllerSourceTypeCamera;

    cameraView.frame = photo.cameraOverlayView.frame;
    photo.cameraOverlayView = cameraView;



    // photo.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    //[photo setCameraOverlayView:cameraView];

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

我在文档中看到 - （void）takePicture，但是如何在单击图片时运行代码？

通过将self注册为UIImagePickerController的代表，您可以覆盖- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info。
