As answered in this post; Compare version numbers in Objective-C

Check out my NSString category that implements easy version checking on github; https://github.com/stijnster/NSString-compareToVersion

[@"1.2.2.4" compareToVersion:@"1.2.2.5"];

This will return a NSComparisonResult which is more accurate then using;

[@"1.2.2" compare:@"1.2.2.5" options:NSNumericSearch]

Helpers are also added;

[@"1.2.2.4" isOlderThanVersion:@"1.2.2.5"];
[@"1.2.2.4" isNewerThanVersion:@"1.2.2.5"];
[@"1.2.2.4" isEqualToVersion:@"1.2.2.5"];
[@"1.2.2.4" isEqualOrOlderThanVersion:@"1.2.2.5"];
[@"1.2.2.4" isEqualOrNewerThanVersion:@"1.2.2.5"];
