While overall it's pretty straightforward, there are some things that can make life a little tricky. However, for reference I've also put up a simple gist of a sign-in implementation that includes an AppDelegate and a ViewController with the sign-in button on.In this case though, we'll take a look at some problems that might bite you during development, and some that might hit later on.Forgetting the resource bundleWhen you include the Google+ iOS SDK, you need three files: GoogleOpenSource.framework, GooglePlus.framework, and GooglePlus.bundle.
