Hide Status Bar and Increase the Height of Uinavigationbar

Hide Status Bar and Increase the height of UINavigationBar

To start off, you hide your statusBar by following these steps:

First, put this code in viewWillAppear:

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

Second, set your info.plist file as the below image shows:

Next, you can make a Category of UINavigationBar and in it set the height of the navigaionBar.

Objective-c

in .h file

@interface UINavigationBar (Custom)
- (CGSize)sizeThatFits:(CGSize)size ;

and in .m file

@implementation UINavigationBar (Custom)

- (CGSize)sizeThatFits:(CGSize)size {
    CGFloat width = [UIScreen mainScreen].bounds.size.width;
    CGSize newSize = CGSizeMake(width, 100);
    return newSize;
}

Swift

extension UINavigationBar {
    public override func sizeThatFits(size: CGSize) -> CGSize {
        let width = UIScreen.mainScreen().bounds.width
        let newSize = CGSize(width: width, height: 64)
        return newSize
    }
}

UINavigationBar has wrong height because the status bar is hidden while loading

Have you try to reset the navigation and status bar as like below?

-(void)resetNavigationBar
{
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];

    [self.navigationController setNavigationBarHidden:YES];

    [self.navigationController setNavigationBarHidden:NO];
}

Safe area insets change when hiding status bar iOS 11

Constraints that are set to the safe area are affected by the status bar as well as the views actual location on the screen and its transform. If you always want to just apply the top (or bottom) safe area height to your view constraint, you can do this by use of a custom constraint instead.

The following constraint will automatically set its constant value to the height of the device's top safe area height, not affected by the status bar or other parameters. To use it, change the class of any constraint into this, and their constant will always be the safe area height. Note that it will not change its value when the device is rotated.

Objective-C

@interface TopSafeAreaContraint : NSLayoutConstraint

@end

@implementation TopSafeAreaContraint

- (void)awakeFromNib {
    [super awakeFromNib];

    if (@available(iOS 11.0, *)) {
        UIEdgeInsets insets = [UIApplication sharedApplication].keyWindow.safeAreaInsets;
        self.constant = MAX(insets.top, 20.0);
    } else {
        // Pre-iOS 11.0
        self.constant = 20.0;
    }
}

@end

Swift

class TopSafeAreaConstraint: NSLayoutConstraint {
    override func awakeFromNib() {
        super.awakeFromNib()
        if #available(iOS 11.0, *) {
            let insets = UIApplication.shared.keyWindow?.safeAreaInsets ?? .zero
            self.constant = max(insets.top, 20)
        } else {
            // Pre-iOS 11.0
            self.constant = 20.0
        }
    }
}
