I could solve it from

Maybe your sdk versions differ, did you try to recreate the project and just import the code.

If this is a one time change that might be working out.

Try going into the project settings, and changing the base SDK to iOS (4.3).

An option for this can be found in the info and build settings panels of the project window. I recommend changing it in both places
