LazyScrollView

中文说明

中文Demo说明

依赖LazyScrollView, 我们创建了一个模块化页面UI解决方案，详情可见 https://github.com/alibaba/tangram-ios.

LazyScrollView is an iOS ScrollView , to resolve the problem of reusability of views.

We reply an another way to control reuse in a ScrollView, it depends on give a special reuse identifier to every view controlled in LazyScrollView.

Comparing to UITableView , LazyScrollView can easily create different layout , instead of the single row flow layout.

Comparing to UICollectionView , LazyScrollView can create views without Grid layout , and provides a easier way to create different kinds of layous in a ScrollView .

The system requirement is iOS 5+

We create a modular UI solution for building native page dynamically based on LazyScrollView, you can see more info from this repo : https://github.com/alibaba/tangram-ios

Installation

LazyScroll is available as LazyScroll in cocoapods

   pod 'LazyScroll'

If you don't want to use cocoapods, you can also manually add the files in LazyScrollView folder into your Xcode project

Usage

#import "TMMuiLazyScrollView.h"

Then , create LazyScrollView

TMMuiLazyScrollView *scrollview = [[TMMuiLazyScrollView alloc]init];
scrollview.frame = self.view.bounds;

next implementTMMuiLazyScrollViewDataSource

@protocol TMMuiLazyScrollViewDataSource <NSObject>
@required
//number of item om scrollView
- (NSUInteger)numberOfItemInScrollView:(TMMuiLazyScrollView *)scrollView;
//return view model (TMMuiRectModel) by index 
- (TMMuiRectModel *)scrollView:(TMMuiLazyScrollView *)scrollView rectModelAtIndex:(NSUInteger)index;
//return view by the unique string that identify a model(muiID) . You should render the item view here. And the view is probably . Item view display. You should always try to reuse views by setting each view's reuseIdentifier and querying for available reusable views with dequeueReusableItemWithIdentifier:
- (UIView *)scrollView:(TMMuiLazyScrollView *)scrollView itemByMuiID:(NSString *)muiID;
@end

next , set datasource delegate of LazyScrollView

scrollview.dataSource = self;

finally , do reload

[scrollview reloadData];

To view detailed usage , please clone the repo and open project to see demo.
