UINavigationBar Category which allows you to change its appearance dynamically
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:

It is hard to change the appearance of UINavigationBar dynamically, so I made this lib to make the job easy.
First, import this lib: ```objective-c
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~
