SwiftUI Prevent user from tapping button while entering data - swift

Question

If the user clicks the button while editing the TextField (cursor flashing) in DataPtView, the app crashes.
In a list cell, I have the button, which impacts the view that is also shown in the cell.
Here's a snippet, iPad specific.
CellView:
VStack{
Button("TagOut"){
self.tagOut.toggle()
}
if self.tagOut {
TagOutView(question: question)
}
if !self.tagOut{
if question.type == "Y/N"{
YesOrNoView(question: question)
} else if question.type == "DataPt"{
DataPtView(question: question)
} else {
RecordEntryView()
}
...
DataPtView:
...
TextField("Data: ", text: $collectedData)
.onReceive(Just(collectedData)) {value in
let filtered = value.filter {"01234567890-".contains($0)}
if filtered != value{
self.invalidCollectedData = true
} else {
self.invalidCollectedData = false
}
}
...
I'm also using an AdaptsToKeyboard ViewModifier for when CellView is covered by the keyboard.

How do I prevent this from happening? If user hides the keyboard before clicking the button, everything is fine, but that isn't intuitive.

Answer 1

What if you try to check if your modifier height is greater than 0 and based on this handle the button click. In your cell view define:
#State var keyboardHeight: CGFloat = 0
Change your AdaptsToKeyboardModifier to have binding var inside it:
struct AdaptsToKeyboard: ViewModifier {
#Binding var currentHeight: CGFloat = 0
...
}
Now you need to initialize your modifier with the following constructor:
.modifier(AdaptsToKeyboard(currentHeight: $keyboardHeight))
Now you have two options to handle the button press:
To disable the button interaction:
Button("TagOut"){
self.tagOut.toggle()
}.disabled(keyboardHeight > 0)
To ignore the press:
Button("TagOut") {
if self.keyboardHeight == 0 {
self.tagOut.toggle()
}
}
