如何获取已拍摄照片或已拍摄照片的位置（经度/纬度）

Question

This may seem like a duplicate but the Assets Library framework (the current framework most answers are using for the same question) is deprecated as of iOS 9.0 as shown by apples developer docs.

What I need to be able to do is get the lat/lng from a photo which is either currently being taken or a photo which has previously been taken (on a iOS 5+ device as it has location tagging). Some sample code would be great

Thanks

Try this

NSData* pngData =  UIImageJPEGRepresentation(image, 1.0);

CGImageSourceRef mySourceRef = CGImageSourceCreateWithData((CFDataRef)pngData, NULL);

if (mySourceRef != NULL)
{
    NSDictionary *myMetadata = (__bridge NSDictionary *)CGImageSourceCopyPropertiesAtIndex(mySourceRef,0,NULL);
    NSDictionary *GPSDictionary = [myMetadata objectForKey:(NSString *)kCGImagePropertyGPSDictionary];

    NSLog([GPSDictionary valueForKey:(NSString*)kCGImagePropertyGPSLongitude]);
    NSLog([GPSDictionary valueForKey:(NSString*)kCGImagePropertyGPSLatitude]);

}
