中文文档

Requirements

  • Xcode 8.0+
  • iOS 8.0+

Installation

CocoaPods

pod 'DDComponent'

Carthage

github 'DDComponent'

Getting Started

For easy using, the api is similar to UICollectionView and UITableView.

@interface YourComponent : DDCollectionViewSectionComponent
@end

@implementation

- (instancetype)init
{
    self = [super init];
    if (self) {
        self.size = CGSizeMake(DDComponentAutomaticDimension, 44);
        // config here. 
        // Remember self.collectionView is nil until it is added to root component.
    }
    return self;
}

- (void)prepareCollectionView {
    [super prepareCollectionView];
    // register your cell here.
}

- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    return 1;
}

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return 1;
}

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
    return ... // Return your cell
}

@end

And the other api is also the same.

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {
    // select item
}
- (void)collectionView:(UICollectionView *)collectionView willDisplayCell:(UICollectionViewCell *)cell forItemAtIndexPath:(NSIndexPath *)indexPath {
    // will display
}

              [Header] <DDComponentPodDemo.HeaderComponent: 0x608000151ca0>
            <DDComponentPodDemo.TaobaoGoodsComponent: 0x608000152170>
            <DDComponentPodDemo.TaobaoGoodsComponent: 0x6080001515c0>
            <DDComponentPodDemo.TaobaoGoodsComponent: 0x608000151a90>
              [Header] <DDComponentPodDemo.HeaderComponent: 0x608000151f60>
            <DDComponentPodDemo.TaobaoGoodsComponent: 0x608000151930>
            <DDComponentPodDemo.TaobaoGoodsComponent: 0x608000151670>
            <DDComponentPodDemo.TaobaoGoodsComponent: 0x608000152640>
      -[error] <DDComponentPodDemo.StateComponent: 0x608000165340>
      -[noData] <DDComponentPodDemo.StateComponent: 0x608000165400>

Structure

  1. View Component: displaying. for example, a list of cell or just an element。
  2. Container Component: combine the view components. For example, conbine some components as a list, or switch between different components(Loading, Error, Empty). And the root component is also a containter component.

We need to do is only the red part.

Attension

Use size, inset first, then override the delegate api.

Some Question

As use the system api, indexPath is the UICollectionView‘s location. It is not the index of component’s dataSource.

Revision

0.5.2 Optimize the numberOf. Add dataSource cache and collectionView cache.

0.5.1 Only support UICollectionView.

0.5.0 New DDComponent using Objective-C.
