Handy tip of the day: To scroll to the top of a UITextView, simply use the following method: [textView setContentOffset:CGPointMake(0.0, 0.0) animated:YES]; Hope it helps!
I really appreciated how Greg Hewgill summarized the difference between the two Git functions “Pull” and “Fetch” on Stackoverflow: In the simplest terms, “git pull” does a “git fetch” followed by a “git merge”. You can do a “git fetch” at any time to update your local copy of a remote branch. This operation never changes any of your own branches and is safe to do without changing your working copy. I have even heard of people running “git fetch” periodically in a cron job in the background (although I wouldn’t recommend doing this). A “git pull” is what you would do to bring your repository up to date with a remote repository.
