Question

I am new to Facebook and Twitter integrations. I am able to integrate them in individual versions, i.e iOS4 and iOS5.

I am facing difficulty in checking the condition that based on the version, need to integrate Twitter and Facebook functionalities.

Can anyone suggest me regarding this.

Answer 1

iOS version check

NSArray *versionCompatibility = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:@"."];

if ( 5 == [[versionCompatibility objectAtIndex:0] intValue] ) { /// iOS5 is installed

    // Put iOS-5 code here

} else { /// iOS4 is installed

    // Put iOS-4 code here         

}

Happy Coding 🙂

EDIT 1

So you can find the iOS version with this also

if (NSClassFromString(@"TWTweetComposeViewController") != nil) { /// iOS5 is installed

    // Put iOS-5 code here

} else { /// iOS4 is installed

    // Put iOS-4 code here         

}
