# RxInfinitable

这个小工程简单实现了下拉刷新数据，上拉加载更多功能。针对上拉加载更多，由于UIKit没有提供类似`UIRefreshControl`的控件，所以我简单的封装了`InfinitableView`。

## 如何使用

有四个步骤：

1. 添加视图

```swift

tableView.refreshControl = refreshControl

infinitableView.attach(to: self.tableView)

```

2. 下拉刷新的请求

```swift

let refreshActivity = ActivityIndicator()

self.refreshing = refreshActivity.asDriver()

let r0 = refreshControl.rx.controlEvent(.valueChanged).asObservable().map { () }

let r1 = r0.startWith(() ).flatMapLatest { [weak self](_) -> Observable<[Int]> in

    let error = NSError(domain: "self.notExsist", code: -1, userInfo: nil)

    guard let self = self else { return .error(error) }

    

    return self.refresh().trackActivity(refreshActivity)

}        

```

3. 上拉加载更多的请求

```swift

let loadActivity = ActivityIndicator()

self.loading = loadActivity.asDriver()

let r2 = infinitableView.rx.didTriggerLoading.flatMapLatest { [weak self] (_) -> Observable<[Int]> in

    let error = NSError(domain: "self.notExsist", code: -1, userInfo: nil)

    guard let self = self else { return .error(error) }

    return self.loadMore().trackActivity(loadActivity)

}.flatMapLatest { [weak self] (list) -> Signal<[Int]> in

    guard let self = self else { return .empty() }

    self.datasource.append(contentsOf: list)

    return .just(self.datasource)

}

```

4. 设置请求的互斥状态。即在刷新时不能再加载更多，反之亦然。

```swift

Driver.combineLatest(self.refreshing, self.loading).drive(onNext: { [weak self] (arg0) in

    guard let self = self else { return }

    let (refreshing, loading) = arg0

    self.infinitableView.isEnabled = !refreshing

        

    if !loading {

        self.tableView.refreshControl = self.refreshControl

    } else {

        self.tableView.refreshControl = nil

    }

}).disposed(by: bag)

```
