我正在使用Form
创建一个SwiftUI
。在我的Form
中,我有一个DatePicker
,TextField
和一个SegmentedPickerStyle
。
我的TextField
使用的是.decimalPad
,我正在尝试找到完成打字后关闭键盘的最佳方法。
我尝试添加.onTapGesture
,但它阻止了我使用任何选择器。当我点击它们时,什么也没发生。
这就是我想要做的:
struct ContentView: View {
@State var date = Date()
@State var price = ""
@State private var tipPercentage = 2
let tipPercentages = [10, 15, 20, 25, 0]
var body: some View {
NavigationView {
Form {
Section {
DatePicker(selection: $date, displayedComponents: .date) {
Text("Date").bold().foregroundColor(Color.init(red: 100.0/255.0, green: 208.0/255.0, blue: 100.0/255.0))
}
HStack {
Text("Price"))
Spacer()
TextField("required", text: $price).multilineTextAlignment(.trailing).keyboardType(.decimalPad)
}
}
Section(header: Text("How much tip do you want to leave?")) {
Picker("Tip percentage", selection: $tipPercentage) {
ForEach(0 ..< tipPercentages.count) {
Text("\(self.tipPercentages[$0])%")
}
}
.pickerStyle(SegmentedPickerStyle())
}
}
.onTapGesture {
let keyWindow = UIApplication.shared.connectedScenes
.filter({$0.activationState == .foregroundActive})
.map({$0 as? UIWindowScene})
.compactMap({$0})
.first?.windows
.filter({$0.isKeyWindow}).first
keyWindow!.endEditing(true)
}
}
}
}

删除您的.onTapGesture并将其添加到表单中:
.gesture(DragGesture().onChanged{_ in UIApplication.shared.sendAction(#selector(UIResponder.resignFirstResponder), to: nil, from: nil, for: nil)})

您将要使用一些UIKit来完成此操作。
首先,创建一个自定义手势识别器:
class CloseKeyboardGestureRecognizer: UIGestureRecognizer {
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent) {
// Don't run if the tap is in a TextField, since the keyboard shouldnt hide when tapping a textfield.
guard let touch = touches.first?.view, touch is UITextField else {
state = .began
return
}
state = .failed
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
state = .ended
}
override func touchesCancelled(_ touches: Set<UITouch>, with event: UIEvent) {
state = .cancelled
}
}
extension CloseKeyboardGestureRecognizer: UIGestureRecognizerDelegate {
func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
return true
}
}
然后在SceneDelegate中的场景(_:willConnectTo:options :)中添加:
let gesture = CloseKeyboardGestureRecognizer(target: window, action:#selector(UIView.endEditing))
gesture.delegate = gesture
gesture.cancelsTouchesInView = false
gesture.requiresExclusiveTouchType = false
window.addGestureRecognizer(gesture)
}
这是一种行为,即在文本字段外部点击会关闭键盘,而不会影响其他元素上的点击。
