//UIImage *image= [info objectForKey:UIImagePickerControllerOriginalImage]; 

NSURL *assetURL = [info objectForKey:UIImagePickerControllerReferenceURL]; 

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

[library assetForURL:assetURL 

resultBlock:^(ALAsset *asset) { 

NSDictionary* imageMetadata = [[NSMutableDictionary alloc] initWithDictionary:asset.defaultRepresentation.metadata]; 

NSDictionary *GPSDict=[imageMetadata objectForKey:(NSString*)kCGImagePropertyGPSDictionary]; 

NSLog(@"%@",GPSDict); 

NSLog(@"%@",imageMetadata);
