Swiftui 可搜索取消按钮

Question

I have a NavigationView with .searchable , when clicking Cancel I want to go to the previous View like Back button. İ use @Environment(\.isSearching) , it is running, I can print Searching canceled but how to navigate to the previous View?

Answer 1

You can simply listen to the changes made to isSearching , and pop your view using @Environment(\.presentationMode) :

.onChange(of: isSearching) { newValue in
    guard !newValue else {return}
    presentationMode.wrappedValue.dismiss()
    //for iOS 16 +, use dismiss.callAsFunction()
}

Note: presentationMode is first deprecated in iOS 15+, so for newer versions use @Environment(\.dismiss) .

Answer 2

If you are using iOS 13+, you can use @Environment(\.dismiss) var dismiss And then use dismiss() in the action
