ReusableNestingScrollview

Extended Reading | 中文 | 扩展阅读

ReusableNestingScrollview is a component to solve the problem of SubView global reuse and recovery in rolling views. Unlike traditional similar solutions, RNS does not need to inherit a special ScrollView, does not need to inherit a special Model ,only by extending the Delegate, so that the rolling views such as WKWebView, UIWebView, and so on are more widely supported, more general and independent.

Together with WKWebViewExtension, sub repo of HybridPageKit, which is a general sulotion of news App content page.

Requirements

iOS 8.0 or later

Installation

1. CocoaPods

   platform :ios, '8.0'
   pod 'ReusableNestingScrollview'
   

2. Cloning the repository

   #import "RNSHandler.h"

Features

1. Easy integration, just need 10+ lines code.
2. Do not need inherit special ScrollView and special Model. Support WKWebView & UIWebView.
3. Data-driven, Protocol Oriented Programming.
4. Add workrange. Better view`s state management, flexible handling of business logic.
5. Scroll reuse & Global reuse, and Thread safe.

#Usage

1. Extend View`s Model By RNSModelProtocol

@interface TestModel : NSObject <RNSModelProtocol>
	
RNSProtocolImp(_uniqueId, _componentFrame, [componentView class],[componentController class], _customContext); 

2. Config ScrollView delegate

_handler = [[RNSHandler alloc]initWithScrollView:scrollView
                      externalScrollViewDelegate:self 
                        scrollWorkRange:200.f 
                        componentViewStateChangeBlock:^(RNSComponentViewState state, 
                        NSObject<RNSModelProtocol> *componentItem, __kindof UIView *componentView) {
    
    // handle component state change
    // will Prepare & will Display & end Display & end prepare
}];

3. reload Data with Model

[_handler reloadComponentViewsWithProcessBlock:^(NSMutableDictionary<NSString *,NSObject<RNSModelProtocol> *> *componentItemDic) {        
	
	// update model`s origin
}];
