Calling the appropriate setStatusBarHidden per iOS version

Today my app approved, but I got emails from users says it crash. I figured out that

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation: UIStatusBarAnimationSlide];

Is the problem, Because users have firmware 3.1.x this API is not working and app crash.

So I have replace it with

    if ([[[UIDevice currentDevice] systemVersion] floatValue]>=3.2)
        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation: UIStatusBarAnimationSlide];
    else 
        [[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES];

My questions...

Is what I did the best solution?

Why XCODE did not warn me that SetStatusBarHidden withAnimation is not in 3.0 while I set my Traget OS firmware 3.0?

Do I have to check on every API to see if it is working with my Target OS?

Thank you

I'd recommend you to use the following snipplet of code instead of checking against the version of the os, rather check if a selector is currently available.

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