Access Photo Library via Objective-C/Xcode in iOS
提问by Objc55
I'm writing an iPhone application. I'm wondering if I can get a list of files/filenames of the photos stored in the iPhone library (or those in the simulator).
我正在编写一个 iPhone 应用程序。我想知道是否可以获得存储在 iPhone 库（或模拟器中的照片）的文件/文件名列表。
Essentially, I'm asking if I can get the filenames of the photos stored on the iPhone or simulator.
本质上，我是在问我是否可以获取存储在 iPhone 或模拟器上的照片的文件名。
I appreciate any help, thanks!
我感谢任何帮助，谢谢！
EDIT:
编辑：
image = [UIImage imageNamed:@"/Users/Library/Application Support/iPhone Simulator/5.0/Media/DCIM/100APPLE/IMG_0002.jpg"];
imageView.image = image;
doesn't work, unfortunately.
不幸的是，不起作用。

You simply have to use the UIImagePickerController.
您只需使用UIImagePickerController.
It gives something like that:
它给出了这样的东西：
-(IBAction) getPhoto:(id) sender {
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
// Don't forget to add UIImagePickerControllerDelegate in your .h
picker.delegate = self;
if((UIButton *) sender == choosePhotoBtn) {
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
} else {
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
}
[self presentModalViewController:picker animated:YES];
}

This is something of a duplicate of a SO question asked already here - Get list of all photo albums and thumbnails for each album
这是这里已经提出的 SO 问题的重复 -获取每个相册的所有相册和缩略图的列表
From that answer: Take a look at AssetsLibraryframework.
从那个答案：看看AssetsLibrary框架。
Note that if you have access to the iOS 6 Beta, you'll want to note the changes taking place for accessing those assets. Can say no more per NDA.
请注意，如果您有权访问 iOS 6 Beta，则需要注意访问这些资产所发生的更改。每个 NDA 不能再说了。
