And has been discussed in the rest of the thread, you should not leave your Base SDK set to an earlier OS and then invoke methods introduced in a later OS, because the new methods may require new-OS framework behavior. It is a very strong recommendation that you set your Base SDK to Latest and use the Deployment Target to specify the least recent OS on which your application will be run.
