IOS/Objective-C/imagePicker：跳过“选择”步骤

Question

我的 uiimagepicker 控制器方法让用户选择照片，一旦选择，询问用户是否要“选择照片”。

但是，我遇到了另一个跳过此步骤的项目。用户点击照片的那一刻，它被选中，选择器被关闭，我们在原始控制器中看到图像。我更喜欢这个，因为它更快。

谁能解释如何跳过“选择”步骤？

Here is my code:
- (IBAction)selectPhoto:(id)sender {
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    [self presentViewController:picker animated:YES completion:NULL];

}

#pragma mark - Image Picker Controller delegate methods

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

    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
    self.imageView.image = chosenImage;
    self.changedPic=YES;
    [picker dismissViewControllerAnimated:YES completion:NULL];

}

这是跳过该步骤的其他代码：

- (IBAction) pickImage:(id)sender{

    UIImagePickerController *pickerController = [[UIImagePickerController alloc] init];
    pickerController.delegate = self;
    [self presentViewController:pickerController animated:YES completion:nil];
}

#pragma mark -
#pragma mark UIImagePickerControllerDelegate

- (void) imagePickerController:(UIImagePickerController *)picker
         didFinishPickingImage:(UIImage *)image
                   editingInfo:(NSDictionary *)editingInfo
{
    self.imageView.image = image;
    pngData = UIImagePNGRepresentation(image);
    [self dismissModalViewControllerAnimated:YES];
}

我没有立即看出是什么导致了差异，但也许有一些委托方法或可以做到这一点的东西。感谢您的任何建议。
