Question

Is the Janrain iOS library for Engage compatible with IOS 5?

Answer 1

I am just getting started with the Engage iOS SDK too. The instructions on the Janrain site are not for iOS 5 / Xcode 4. They are targeted at earlier versions of iOS running under Xcode 3. It is still possible to drag/drop the JREngage source folder into your project. The trick is to not use a project that has ARC enabled. When you enable ARC you will get all sorts of compiler errors and warnings and it will fail to build. If you create a new project in Xcode 4 and uncheck the Use Automatic Reference Counting option it should build okay.

I have submitted a support request to Janrain in hopes of getting some clarification on whether this is expected behavior and what their plans are for supporting ARC. When I get a response I will update my comment here.

Here is the response I received from Janrain. It looks like the Engage SDK does not build with ARC enabled, but following their suggested steps you can have it built without ARC within a project that does use ARC.

To use ARC with the Janrain Engage for iOS library, please follow these steps:

1. Go to your project settings, select your application’s target(s) and click the “Build Phases” tab
2. Expand the section named “Compile Sources”
3. Select all the files from the JREngage library, including SFHFKeychainUtils.m and JSONKit.m
4. Hit Enter, to edit all the files at once, and in the floating text box add the -fno-objc-arc compiler flag
