Question

I was making a basic method that takes a Flickr image URL and returns the image’s ID.
I’m passing the method the NSString @"http://farm6.staticflickr.com/5183/5629026092_c6762a118f".

The goal is to return the int: 5629026092, which is in the image’s URL and is the image’s ID.

Here is my method:

-(int)getImageIDFromFlickrURL:(NSString *)imageURL{
    NSArray *objectsInURLArray = [imageURL componentsSeparatedByString:@"/"];
    NSString *lastObjectInFlickrArray = [objectsInURLArray lastObject];
    NSArray *dirtyFlickrIdArray = [lastObjectInFlickrArray componentsSeparatedByString:@"_"];
    NSString *flickIDString = [dirtyFlickrIdArray objectAtIndex:0];
    NSLog(@"flickr id string: %@",flickIDString);
    int flickrID = [flickIDString intValue];
    NSLog(@"id: %i",flickrID);
    return flickrID;
}

The output in the console is:

2012-05-26 13:30:25.771 TestApp[1744:f803] flickr id string: 5629026092
2012-05-26 13:30:25.773 TestApp[1744:f803] id: 2147483647

Why is calling intValue deforming the actual number?

Answer 1

Use long long instead, your number is greater than int can handle (max being 2147483647 as you can see in your second log)
