Hello:
I am trying to display some text in an NSTextView but thus far my efforts have been unsuccessful. Line 27, where I try to code to get the text to display causes a crash. the debug error message is: 2019-11-21 20:09:38.876811-0500 ScorcentMasterReview[49322:25437243] -[NSTextView documentView]: unrecognized selector sent to instance 0x101094620.
When I comment out line 27, the debug message is given below:
Any help would be appreciated.
Here is the code:
@IBActionfunc getQuestion(_ sender: Any) {
func runConsistencyCheck() {
do {
try managedContext.save()
} catch {
print("An error occurred during consistency checking: \(error)")
}
}
// print ("Starting Fetch Function")
guard let appDelegate = NSApplication.shared.delegate as? AppDelegate else {
return
}
// print ("Step Four")
_ = appDelegate.persistentContainer.viewContext
let fetchRequest = NSFetchRequest(entityName: "SCQ")
fetchRequest.returnsObjectsAsFaults = false
do {
items = try managedContext.fetch(fetchRequest)
print ("Record Returned is \(items)")
} catch let error as NSError {
print("Could not fetch. \(error), \(error.userInfo)")
}
for item in items {
if let record = item.value(forKey: "question") as? String {
recordItem.append(record)
let stringvalue = "questionText: \(recordItem)"
questionView?.documentView?.insertText(stringvalue) //THIS LINE CAUSES A CRASH
print(stringvalue)
}
}
for item in items {
if let record = item.value(forKey: "distractor1") as? String {
distractor1Item.append(record)
let stringvalue = "distractor1Label: \(distractor1Item)"
print(stringvalue)
}
}
for item in items {
if let record = item.value(forKey: "distractor2") as? String {
distractor2Item.append(record)
let stringvalue = "distractor2Label: \(distractor2Item)"
print(stringvalue)
}
}
for item in items {
if let record = item.value(forKey: "distractor3") as? String {
distractor3Item.append(record)
let stringvalue = "distractor3Label: \(distractor3Item)"
print(stringvalue)
}
}
for item in items {
if let record = item.value(forKey: "distractor4") as? String {
distractor4Item.append(record)
let stringvalue = "distractor4Label: \(distractor4Item)"
print(stringvalue)
}
}
for item in items {
if let record = item.value(forKey: "distractor5") as? String {
distractor5Item.append(record)
let stringvalue = "distractor5Label: \(distractor5Item)"
print(stringvalue)
}
}Here is the debug results when I comment out line 27 where I try to get the output:
questionText: (see figure) Using the maps; Which one of these was probably most recently settled?
distractor1Label: Iron Town
distractor2Label: Lake City
distractor3Label: Jonesville
distractor4Label: not here
