拍照并保存到相册

Question

我使用此代码来拍照：

-(IBAction) getPhoto:(id) sender {
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;

if((UIButton *) sender == choosePhotoBtn) {
    picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
} else {
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
}

[self presentModalViewController:picker animated:YES];

}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissModalViewControllerAnimated:YES];
    imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
}

我想知道如何将我拍摄的这张照片保存到相册中。

查看 UIKit 函数参考，用途：

UIImageWriteToSavedPhotosAlbum()

用途：

UIImageWriteToSavedPhotosAlbum(theImage, nil, nil, nil);
