Iphone application crashes

Question

由于这行代码，我的应用程序崩溃了

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:YES];

Answer 1

I have used your code in my applications, but i am not getting any crash in my all applications.

Can you put full method code?

And try clean your project , delete it from simulator and run it.
