Previously when you wanted to share something, it involved copying the text or a link and then launching the Twitter program to post the Tweet. Now when you hit the Share button in an app, you can just select the Tweet option. Users can also upload pictures directly to Twitter using Twitter’s own picture hosting service. Twitter integration is available in default apps like Camera, Maps, Photos, Safari, YouTube and third party apps like Chomp, Flipboard, Instagram and more.
Get the official Twitter app for your iOS device from the Apple App Store.
