E--xcode the current deployment target does not support automated __weak references

__weak references only work on iOS 5 and above. If you have the deployment target set to anything earlier, then you'll get the error. Basically, if you want to deploy to earlier devices you can't use automated __weak references. The substitute would be __ unsafe_unretained
