# UINavigationBar-FixedHeightWhenStatusBarHidden

Normally on iOS 7+ navigation bar height equals to 64 px, when status bar is shown. After it is hidden, the height is changed to 44 px by default.

This category adds property `fixedHeightWhenStatusBarHidden` to UINavigationBar class. If set to YES navigation bar will keep its size even if status bar was hidden.

This is especially useful in case of "drawer"-styled side panel, when you want status bar to be hidden when this panel is shown.

## Installation

Manual:
 
Copy source files from `UINavigationBar-FixedHeightWhenStatusBarHidden` folder to your Xcode project.
 
 
CocoaPods:
 
UINavigationBar-FixedHeightWhenStatusBarHidden is available through [CocoaPods](http://cocoapods.org). To install
it, add the following line to your Podfile:
<pre>
pod 'UINavigationBar-FixedHeightWhenStatusBarHidden'
</pre>

## How to Use

Add `#import "UINavigationBar+FixedHeightWhenStatusBarHidden.h"`.

Enable fixed height with:
```objective-c
self.navigationController.navigationBar.fixedHeightWhenStatusBarHidden = YES;
```

On iOS 11+ you should also set correct additional safe area insets on each view controller presented inside `UINavigationController` with fixed height enabled. This can be done by overriding `viewWillLayoutSubviews` of `UIViewController`. Then you can install the required insets automatically:
```objective-c
- (void)viewWillLayoutSubviews {
    [super viewWillLayoutSubviews];
    [self.navigationController.navigationBar setAdditionalSafeAreaInsetsForViewController:self];	
}
```

Or in case you need to customize insets, use `[UINavigationBar additionalSafeAreaInsets]` selector to get insets required for fixed height to work and modify them according to your needs:
```objective-c
- (void)viewWillLayoutSubviews {
   [super viewWillLayoutSubviews];

if (@available(iOS 11.0, *)) {
        UIEdgeInsets navigationBarSafeAreaInsets = [self.navigationController.navigationBar additionalSafeAreaInsets];
        self.additionalSafeAreaInsets = UIEdgeInsetsMake(navigationBarSafeAreaInsets.top + 20, 0, 0, 0);
    }
}
```
