## Deprecated

This lib uses a hacky way to achieve the result, in the new iOS version, the structure of UINavigation is changed and this lib no longer works anymore, so please check these alternatives:

- https://github.com/andreamazz/AMScrollingNavbar

- https://github.com/DanisFabric/RainbowNavigation

- https://github.com/MoZhouqi/KMNavigationBarTransition

## swift version

[https://github.com/ltebean/LTNavigationBar/tree/swift3.0](https://github.com/ltebean/LTNavigationBar/tree/swift3.0)

## Purpose

It is hard to change the appearance of UINavigationBar dynamically, so I made this lib to make the job easy.

## Demo

#### 1. Changing the background color:

#### 2. Making navigation bar scroll along with a scroll view:

## Usage

First, import this lib:

```objective-c

#import "UINavigationBar+Awesome.h"

```

The category includes lots of method that helps to change UINavigationBar's appearance dynamically:

```objective-c

@interface UINavigationBar (Awesome)

- (void)lt_setBackgroundColor:(UIColor *)backgroundColor;

- (void)lt_setElementsAlpha:(CGFloat)alpha;

- (void)lt_setTranslationY:(CGFloat)translationY;

- (void)lt_reset;

@end

```

You can call the various setter wherever you want, like:

```objective-c

[self.navigationController.navigationBar lt_setBackgroundColor:[UIColor blueColor]];

```

And usually in `viewWillDisappear`, you should call this method to avoid any side effects:

```objective-c

- (void)viewWillDisappear:(BOOL)animated

{

    [super viewWillDisappear:animated];

    [self.navigationController.navigationBar lt_reset];

}

```

See the example for details~
