访问图像路径

Question

我想让Path获得iPhone设备上相册的图像。而且我还需要用他们的名字扩展那个图像。

Answer 1

我没有尝试过，但请查看UIImagePickerControllerDelegate和didFinishPickingMediaWithInfo方法。我认为图像的实际路径是隐藏的，但info词典有一个名为UIImagePickerControllerReferenceURL的键，看起来它可能是原始图像的NSURL。

UIImagePickerControllerReferenceURL
The Assets Library URL for the original version of the picked item.
After the user edits a picked item—such as by cropping an image or trimming a movie—the URL continues to point to the original version of the picked item.
The value for this key is an NSURL object.
Available in iOS 4.1 and later.
Declared in UIImagePickerController.h

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