Answer 1

Try this

   - (void)imagePickerController:(UIImagePickerController *)picker 
didFinishPickingMediaWithInfo:(NSDictionary *)info {
    NSURL *assetURL = [info objectForKey:UIImagePickerControllerReferenceURL];

  ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];

  [library assetForURL:assetURL resultBlock:^(ALAsset *asset) {
   ALAssetRepresentation *representation = [asset defaultRepresentation];
   metadataDict = [[representation metadata] retain]; 
   NSLog(@"%@",metadataDict);


  } failureBlock:^(NSError *error) {
   NSLog(@"%@",[error description]);
  }];
[library release];
}

you have have to declare it with the __block identifier as well.

       __block NSDictionary *metaDataDict;

我认为您必须使用ALAsset类，因为我不确定UIImage是否提供您需要的所有信息（尤其是GPS信息）。

您无法从库中获取图像的“真实”路径，即使可以获取，也无法访问。
