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+
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
#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;
@endnext , 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.
