Method that Hides Status Bar

[[UIApplication sharedApplication] setStatusBarHidden:YES];

Alternate Way to Hide Status Bar

We can also hide the status bar with the help of info.plist by adding a row and selecting UIStatusBarHidden and make its value to NO.

Add a Custom Method hideStatusbar to our Class

It hides the status bar animated and also resize our view to occupy the statusbar space.

-(void)hideStatusbar {
   [[UIApplication sharedApplication] setStatusBarHidden:YES 
   withAnimation:UIStatusBarAnimationFade];
   [UIView beginAnimations:@"Statusbar hide" context:nil];
   [UIView setAnimationDuration:0.5];
   [self.view setFrame:CGRectMake(0, 0, 320, 480)];
   [UIView commitAnimations];
}

Update viewDidLoad in ViewController.m as follows −

- (void)viewDidLoad {
   [super viewDidLoad];
   
   // The method hideStatusbar called after 2 seconds
   [self performSelector:@selector(hideStatusbar) 
   withObject:nil afterDelay:2.0];
   
   // Do any additional setup after loading the view, typically from a nib.
}

Initial output and output after 2 seconds −
