通过iOS中的Objective-C/Xcode访问Photo Library

Question

我正在写一个iPhone应用程序.我想知道我是否可以获得存储在iPhone库(或模拟器中的那些)中的照片的文件/文件名列表.

基本上,我问我是否可以获取存储在iPhone或模拟器上的照片的文件名.

我感谢任何帮助,谢谢!

编辑:

image = [UIImage imageNamed:@"/Users/Library/Application Support/iPhone Simulator/5.0/Media/DCIM/100APPLE/IMG_0002.jpg"];
imageView.image = image;

不幸的是,它不起作用.

你只需要使用UIImagePickerController.

它给出了类似的东西:

-(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];
}
