问题
I want to get location information of any image/video from asset library using ALAssetPropertyLocation but it's returning nil information.Followings are my fraction of code.
[workingDictionary setObject:[asset valueForProperty:ALAssetPropertyLocation] forKey:@"Location"];
Can anyone give me any image where location metadata is present.I tried with image taken from iPhone photo library but the things are same.Can anyone tell me where I am doing wrong?
