Hide Status Bar and Increase the height of UINavig

问题:

I am using story board to create navigation bar.

My requirement is to hide the status bar and increase the height of Navigation bar. When i hide the status bar, the navigation bar sticks to top and the height is 44 px. i need a navigation bar height as 64 px (44px+status bar height). Is there any way to do this?

Without status bar

回答1:

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
    }
}
