SwiftUI 中使用BBSwiftUIKit开源库实现上拉加载和下拉刷新

BBSwiftUIKit开源库GitHub地址

import SwiftUI
import BBSwiftUIKit

struct ContentView: View {
    
    @State var list : [Int] = (0..<50).map{$0}
    @State var isRefreshing: Bool = false
    @State var isLoadingMore: Bool = false
    @State var isReloadData: Bool = false
    var body: some View {
        BBTableView(list) { i in
            Text("Text(i)")
                .padding()
                .background(Color.blue)
        }
        //调用该方法后isRefreshing会变为true
        .bb_pullDownToRefresh(isRefreshing: $isRefreshing) {
            print("Refresh")
            //设置为一秒后停止刷新
            DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
                self.list = (0..<50).map{$0}
                self.isRefreshing = false
            }
        }
        .bb_pullUpToLoadMore(bottomSpace: 40) {
            if self.isLoadingMore{return}
            self.isLoadingMore = true
            print("Loading More")
            DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
                let more = (self.list.count..<self.list.count + 10)
                self.list.append(contentsOf: more)
                self.isLoadingMore = false
            }
            
        }
        .bb_reloadData($isReloadData)
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

BBScrollView的使用

import SwiftUI
import BBSwiftUIKit

struct ScrollViewTest: View {
    
    
    @State var contentOffset: CGPoint = .zero
    @State var contentOffsetToScrollAnimated: CGPoint? = CGPoint(x: 200.0, y: 0.0)

    var body: some View {
        let list : [Int] = (0..<50).map{$0}
        BBScrollView(.horizontal, contentOffset: $contentOffset) {
            // Add views
            HStack(spacing:0) {
                ForEach(list,id:.self) { i in
                    Text("(i)")
                        .frame( UIScreen.main.bounds.width/10, height: 30, alignment: .center)
                        .background(Color.blue)
                        
                }
            }
        }
        .bb_bounces(false) // 反弹效果
        .bb_isPagingEnabled(true) // 分页效果
        .bb_showsHorizontalScrollIndicator(false) // 是否显示水平滚动条
        .bb_showsVerticalScrollIndicator(false)
    }
}

struct ScrollViewTest_Previews: PreviewProvider {
    static var previews: some View {
        ScrollViewTest()
    }
}
