RRNavigationBar

bring UINavigationBar to UIViewController.

Introduction

KMNavigationBarTransition provide 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 10.2 + Xcode 8.2.1, the minimum support version is iOS7 in theory, but without test passed.

CocoaPods

CocoaPods is a dependency manager for Cocoa projects.

CocoaPods 0.36 adds supports for Swift and embedded frameworks. You can install it with the following command:

$ gem install cocoapods

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

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '7.0'
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 ViewController's 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 see the demo in project.

Supported Methods

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

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

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