LazyScrollView UI Tangram-iOS

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

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.

We create a modular UI solution for building UI page dynamically based on LazyScrollView, you can see more info from this repo: Tangram-iOS


LazyScroll is available as LazyScroll in CocoaPods.

pod 'LazyScroll'

You can also download the source files from release page and add them into your project manually.


#import "TMMuiLazyScrollView.h"

Then, create LazyScrollView:

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

Next, implement TMMuiLazyScrollViewDataSource:

@protocol TMMuiLazyScrollViewDataSource <NSObject>


// Number of items in scrollView.
- (NSUInteger)numberOfItemInScrollView:(TMMuiLazyScrollView *)scrollView;

// Return the 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.
// You should ALWAYS try to reuse views by setting each view's reuseIdentifier.
- (UIView *)scrollView:(TMMuiLazyScrollView *)scrollView itemByMuiID:(NSString *)muiID;


Next, set datasource of LazyScrollView:

scrollview.dataSource = self;

Finally, do reload:

[scrollview reloadData];
