如何处理来自UIImagePickerController的多个图像？

Question

我对XCode比较陌生，我不明白如何让用户从UIImagePickerControler中选择多个图像。这是我当前的代码，允许用户选择一个图像：

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];

然后，为了处理选择的图像，我使用：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[self dismissModalViewControllerAnimated:YES];
    UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];
    //do stuff with image
}

如何修改代码的两个部分以允许用户选择多个图像。提前谢谢。

Answer 1

查看Asset Library APIs。它们允许您执行ImagePicker内部执行的操作。然后，您可以添加自己的逻辑（即多选）。  Here's a nice tutorial for that.

UIImagePickerController没有用于多个图像拾取的API - 但这可能会给你一个开始： http://www.iphonedevsdk.com/forum/iphone-sdk-development/55351-uiimagepickercontroller-multi-select-photos.html

不幸的是，您必须构建自定义界面才能使其正常工作。
