Rotation background gradient xcode

I have a problem with my background gradient on my app. I set in viewDidLoad in MainViewController.

CAGradientLayer *bgLayer = [BackgroundGradient blackGradient];
bgLayer.frame = self.view.bounds;
[self.view.layer insertSublayer:bgLayer atIndex:0];

and every UIViewController extends from MainViewController. It works fine but after rotate device it show me only half background. Other is white. Can you help? Where can be the problem and show me it only half after rotate?example

In BackgroundGradient.m

@implementation BackgroundGradient
+ (CAGradientLayer*) blackGradient {

    UIColor *colorOne = [UIColor colorWithRed:0.12 green:0.13 blue:0.13 alpha:1.0];
    UIColor *colorTwo = [UIColor colorWithRed:0.11 green:0.12 blue:0.13 alpha:1.0];

    NSArray *colors = [NSArray arrayWithObjects:(id)colorOne.CGColor, colorTwo.CGColor, nil];
    NSNumber *stopOne = [NSNumber numberWithFloat:0.0];
    NSNumber *stopTwo = [NSNumber numberWithFloat:1.0];

    NSArray *locations = [NSArray arrayWithObjects:stopOne, stopTwo, nil];

    CAGradientLayer *headerLayer = [CAGradientLayer layer];
    headerLayer.colors = colors;
    headerLayer.locations = locations;

    return headerLayer;
}

Save your layer into controller property, than override layoutSubviews method and update layer frame.

- (void)layoutSubviews {
    [super layoutSubviews];
    self.backgroundLayer.frame = self.view.bounds;
}
