RRNavigationBar

bring UINavigationBar to UIViewController.

Introduction

KMNavigationBarTransition provides a grace method deal with navigationBar transition, and requires zero line of code changes, which is awesome.

Here is the situation I couldn't doing well by using KMNavigationBarTransition: first page is a product list, click product line, push to product details page, requires transparent navigationBar, while you scrolling, it could recover to default navigationBar's appearance. Continue push to the next page, the navigationBar needs to look like the first page, which is the default appearance. (like the following 1st gif tells.)

In a word, what I wanted is change the navigationBar's appearance only affect current viewController, which is this repo trying to do.

 

Requirements

  • iOS 7.0+

My working environment is iOS 11.0 & Xcode 9, the minimum support version is iOS7 in theory, without test passed confirmed.

CocoaPods

CocoaPods is a dependency manager for Cocoa projects.

You can install it with the following command:

$ gem install cocoapods

To integrate RRNavigationBar into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

pod 'RRNavigationBar'

Then, run the following command:

$ pod install

You should open the {Project}.xcworkspace instead of the {Project}.xcodeproj after you installed anything from CocoaPods.

Usage

In UIViewController subclassess viewDidLoad method:

self.rr_navigationBar.xxx = newValue;

If the viewController's view is activated, will take effect immediately, otherwise when viewWillLayoutSubviews called.

For more information checkout the demo in project.

Supported Methods

  • barStyle
  • translucent
  • tintColor
  • barTintColor
  • backgroundColor
  • shadowImage
  • setBackgroundImage:forBarMetrics:
  • alpha
  • backIndicatorImage
  • backIndicatorTransitionMaskImage
  • titleTextAttributes
  • rr_forceShadowImageHidden

Try not change translucent property once you setup, which is may cause navigationBar flash when animation complete with extends container ViewController's view backgroundColor.

Especially in iOS 11, it will cause navigationBar corruption during (push) animation & ViewController's contentView(UIScrollView) jump.

Set hiddenproperty will have no effect, try use setBackgroundImage:forBarMetrics: & shadowImage make navigationBar invisible.

If you don't want to be impacted for specific UINavigationController, use those methods execude it.

  • RRNavigationBarExcludeImpactBehaviorForClass
  • RRNavigationBarExcludeImpactBehaviorForInstance

Also, you can disable/enable pop interactive animation by manipulate ViewController's property: rr_interactivePopGestureRecognizerDisabled.
