SwipeCell 是一个用Swift 5.3开发的 SwiftUI库.目标是为了实现类似iOS Mail程序实现的左右滑动菜单功能. SwipeCell 需要 XCode 12 ,iOS 14
let button1 = SwipeCellButton(buttonStyle: .titleAndImage,
title: "Mark",
systemImage: "bookmark",
titleColor: .white,
imageColor: .white,
view: nil,
backgroundColor: .green,
action: {bookmark.toggle()},
feedback:true
)//你可以将按钮设置成任意View从而实现更复杂的设计以及动态效果
let button3 = SwipeCellButton(buttonStyle: .view, title:"",systemImage: "", view: {
AnyView(
Group{
if unread {
Image(systemName: "envelope.badge")
.foregroundColor(.white)
.font(.title)
}
else {
Image(systemName: "envelope.open")
.foregroundColor(.white)
.font(.title)
}
}
)
}, backgroundColor: .orange, action: {unread.toggle()}, feedback: false)let slot1 = SwipeCellSlot(slots: [button2,button1])
let slot2 = SwipeCellSlot(slots: [button4], slotStyle: .destructive, buttonWidth: 60)
let slot3 = SwipeCellSlot(slots: [button2,button1],slotStyle: .destructiveDelay) cellView()
.swipeCell(cellPosition: .left, leftSlot: slot4, rightSlot: nil)更多的配置选项
cellView()
.swipeCell(cellPosition: .both,
leftSlot: slot1,
rightSlot: slot1 ,
swipeCellStyle: SwipeCellStyle(
alignment: .leading,
dismissWidth: 20,
appearWidth: 20,
destructiveWidth: 240,
vibrationForButton: .error,
vibrationForDestructive: .heavy,
autoResetTime: 3)
)For List
List{
```
}
.dismissSwipeCell()
}For single cell in ScrollView
ScrollView{
VStack{
Text("Mail Title")
.dismissSwipeCellForScrollView()
Text("Mail Content")
....
}
.frame(maxWidth:.infinity,maxHeight: .infinity)
}
.swipeCell(cellPosition: .both, leftSlot: leftSlot, rightSlot: rightSlot,clip: false)For LazyVStack in ScrollView
ScrollView{
LazyVStack{
ForEach(lists,id:\.self){ item in
Text("Swipe in scrollView:\(item)")
.frame(height:80)
.swipeCell(cellPosition: .both, leftSlot:slot, rightSlot: slot)
.dismissSwipeCellForScrollViewForLazyVStack()
}
}
}Get Cell Status
HStack{
Text("Cell Status:")
Text(status.rawValue)
.foregroundColor(.red)
//get the cell status from Environment
.transformEnvironment(\.cellStatus, transform: { cellStatus in
let temp = cellStatus
DispatchQueue.main.async {
self.status = temp
}
})
}
.frame(maxWidth:.infinity,alignment: .center)
.frame(height:100)
.swipeCell(cellPosition: .both, leftSlot: slot, rightSlot: slot)- dismissSwipeCell 在editmode下支持选择
- dismissSwipeCellForScrollView 用于ScrollView,通常用于只有一个Cell的场景,比如说Mail中的邮件内容显示.参看Demo中的演示
- dismissSwipeCellForScrollViewForLazyVStack 用于ScrollView中使用LazyVStack场景.个别时候会打断滑动菜单出现动画.个人觉得如无特别需要还是使用List代替LazyVStack比较好.
由于SwiftUI没有很好的方案能够获取滚动状态,所以采用了 Introspect实现的上述功能.
destructiveDelay 形式的 button，需要在action中添加 dismissDestructiveDelayButton()已保证在alter执行后，Cell复位
- 动画细节仍然不足
- EditMode模式下仍有不足
