You have three choices here to fix your VC UI:

Firs: you can set up the autoresize masks in code or strotyboard.

Second: use didChangeStatusBarFrame:

- (void)application:(UIApplication *)application didChangeStatusBarFrame:(CGRect)newStatusBarFrame {
    if ([UIApplication sharedApplication].statusBarFrame.size.height == 40) {
        // Do adjustment
    }
    else if  ([UIApplication sharedApplication].statusBarFrame.size.height == 20 && oldStatusBarHeight == 40){ // you should keep oldStatusBarHeight 
        // Do adjustment
    }
    else {
        return;
    }
}

Third: register for a Change StatusBarFrame notification in your viewDidLoad:

 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(statusBarFrameChanged:) name:UIApplicationDidChangeStatusBarFrameNotification object:nil];
 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(statusBarFrameWillChange:) name:UIApplicationWillChangeStatusBarFrameNotification object:nil];

And adjust your VC size in statusBarFrameWillChange and statusBarFrameChanged.
