集合视图，类似UITableView或UICollectionView，在布局能力做了增强，支持多种布局方式，并且在同个视图上可以使用多种布局方式，可替代UITableView或UICollectionView使用。
-
可以同时使用多种布局方式
-
类似UITableView或UICollectionView
-
支持多种布局方式，Row、Grid、WaterFlow、Flow等
-
自定义布局
-
元素复用、预加载.
-
支持下拉刷新、支持上拉刷新
-
UITableView for row layout.
-
UICollectionView with UICollectionViewFlowLayout for grid/flow layout.
-
UICollectionView with custom layout.
With CocoaPods, add this line to your Podfile.
pod 'FMCollectionView'
and run pod install, then you're all done!
Or copy *.h *.m files in Sources folder to your project.
- Add collection view to container.
eg.
- (void)viewDidLoad {
[super viewDidLoad];
self.collectionView = [[FMCollectionView alloc] initWithFrame:self.view.bounds];
self.collectionView.sectionsSpacing = 20;
self.collectionView.itemsSpacing = 4;
self.collectionView.delegatesAndDataSource = self;
[self.view addSubview:self.collectionView];
}
- Implement
FMCollectionViewDelegatesAndDataSource, only two methods inFMCollectionViewDataSourceis required, others is optional.
- (NSInteger)numberOfSectionsInCollectionView:(FMCollectionView *)collectionView {
return HomeSectionsTotalCount;
}
- (NSInteger)collectionView:(FMCollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
if (section == HomeSectionsBanners) {
return self.presenter.banners.count > 0 ? 1 : 0;
} else if (section == HomeSectionsCategories) {
return self.presenter.categories.count;
} else if (section == HomeSectionsProducts){
return [self.presenter itemsCount];
} else if (section == HomeSectionsProductsLoadFailed){
return self.presenter.isFetchProductsFailed ? 1 : 0;
}
return 0;
}
- (UIView *)collectionView:(FMCollectionView *)collectionView itemAtIndexPath:(NSIndexPath *)indexPath {
[self.collectionView beginBottomRefleshingIfNeed:indexPath];
if (indexPath.section == HomeSectionsBanners) {
return self.bannersComponent.componentView;
} else if (indexPath.section == HomeSectionsCategories) {
FMBannerModel *model = self.presenter.categories[indexPath.row];
HomeCategoryCell *cell = [collectionView dequeueReusableItemWithId:@"categories_cell" atIndexPath:indexPath itemClass:HomeCategoryCell.class];
[cell setImgUrl:model.onlyPic.picUrl];
return cell;
} else if (indexPath.section == HomeSectionsProducts) {
ProductListModel *data = [self.presenter itemAtIndex:indexPath.row];
HomeProductCell *cell = [collectionView dequeueReusableItemWithId:@"products_cell" atIndexPath:indexPath itemClass:HomeProductCell.class];
[cell.imgView setImgUrl:data.picUrl];
cell.titleLabel.text = data.productShortTitle;
cell.priceLabel.text = [FMBizUtils stringFromPriceInCent:data.minPriceCent];
return cell;
} else if (indexPath.section == HomeSectionsProductsLoadFailed) {
WeakSelf()
FMNoResultBGViewItem *item = [[FMNoResultBGViewItem alloc] init];
item.style = kNoResultBGViewStyleImgTitle;
item.clicked = ^{
[weakSelf.presenter loadAllKindsData];
};
return [[FMNoResultBGView alloc] initWithFrame:collectionView.bounds andItem:item];
} else {
return nil;
}
}
