XCode warning when using deprecated setStatusBarHidden method

Question

I found this on StackOverflow regarding the problem, but was not able to solve my problem.

http://stackoverflow.com/questions/3028255/about-setstatusbarhidden

if([[UIApplication sharedApplication] respondsToSelector:@selector(setStatusBarHidden: withAnimation:)])
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:NO];
else 
    [[UIApplication sharedApplication] setStatusBarHidden:NO animated:NO];

I set my OS deployment target to 3.0, yet I still recieve the warning 'setStatusBarHidden:animated: is deprecated'

I'd like to have no warnings if possible in the project, and not a hack that removes it. Is there a way I'm supposed to set up the project to remove this warning?

I've set the project base SDK to 4.0. And the target Base SDK to 4.0, deployment target SDK to 3.0.

I made these settings for 'All configurations'

Thanks in advance

Update: Apparently the warning only appears in the simulator, not when set for Device.

A deprecation warning means that you are using something that will not be supported in the future. This particular syntax is listed as deprecated here. You get rid of the warning by not using the deprecated method. You should be using setStatusBarHidden:withAnimation: instead

If you wish to support this functionality on both 3.0 and 3.2+ then you will have to write conditional code based upon the target version. There is some useful information on pre-processor macros and functions to help you here.
