如何在iOS中使用拍摄的照片保存GPS数据

Question

I am developing a camera application which can be used to take pictures and save them in a separate album. I used photos framework to save images and now I need to save GPS data (location where the picture is taken) with the picture (may be in metadata). I searched for any method to do this thing using photos framework but I failed, I couldn't find anything related. Any help would be highly appreciated.

This is the peace of code I used to save pictures

[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{

    PHAssetChangeRequest *assetRequest = [PHAssetChangeRequest creationRequestForAssetFromImage:capturedImage];

    placeholder = [assetRequest placeholderForCreatedAsset];

    photosAsset = [PHAsset fetchAssetsInAssetCollection:Album options:nil];

    PHAssetCollectionChangeRequest *albumChangeRequest = [PHAssetCollectionChangeRequest changeRequestForAssetCollection:Album                                                assets:photosAsset];

    [albumChangeRequest addAssets:@[placeholder]];

} completionHandler:^(BOOL success, NSError *error) {

    if (success)
    {

    }
    else
    {

    }

}];

I assume you want the latitude & longitude. Have you tried the location property of PHAsset class?
