使用ZStack做一个简单的实现，效果如下：

使用如下
import SwiftUI
struct ContentView: View {
@State var showToast = false
var body: some View {
Button(action: {
self.showToast.toggle()
}, label: {
Text("Button")
})
.toast(isShow: $showToast, info: "请求成功")
}
}
Toast代码
import SwiftUI
extension View {
func toast(isShow:Binding<Bool>, info:String = "", duration:Double = 0.5) -> some View {
ZStack {
self
if isShow.wrappedValue {
ToastView(isShow:isShow, info: info, duration: duration)
}
}
}
}
struct ToastView: View {
@Binding var isShow:Bool
let info: String
init(isShow:Binding<Bool>,info: String = "", duration:Double = 0.5) {
self._isShow = isShow
self.info = info
changeShow(duration: duration)
}
private func changeShow(duration:Double) {
DispatchQueue.main.asyncAfter(deadline: .now() + duration) {
self.isShow = false
}
}
var body: some View {
ZStack {
Text(info)
.foregroundColor(.white)
.frame(minWidth: 80, alignment: Alignment.center)
.zIndex(1.0)
.padding()
.background(RoundedRectangle(cornerRadius: 10).foregroundColor(.black))
}
.padding()
.animation(.easeIn(duration: 0.3))
.edgesIgnoringSafeArea(.all)
}
}
#if DEBUG
struct ToastView_Previews: PreviewProvider {
static var previews: some View {
ToastView(isShow: .constant(true), info: "ToastView")
}
}
#endif
