How to get cells with different cell classes - ios

Question

I need to get the text from the textfield i.e from KgCustomCell and KgRepsCustomCell. I need to fetch the data from the field, when i run the buttonClicked method.
I have tried to add to instance variables, which contains kg and reps, but the first time i click the button, it's empty. The second time it's okay. But how can i load the data in the most correct way?
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let index = indexPath.row
if indexPath.row == 0 && indexPath.section == 0 {
let exerciseName = tableView.dequeueReusableCellWithIdentifier("Exercise Name", forIndexPath: indexPath) as! LoggedExerciseNameCell
exerciseName.lblExerciseName.text = self.exercise?.name
return exerciseName
}
if index == 0 && indexPath.section == 1 {
let txtFieldKg = tableView.dequeueReusableCellWithIdentifier("Text KG", forIndexPath: indexPath) as! KgCustomCell
return txtFieldKg
}
if index == 1 && indexPath.section == 1 {
let txtFieldReps = tableView.dequeueReusableCellWithIdentifier("Text Reps", forIndexPath: indexPath) as! KgRepsCustomCell
//kg = txtFieldReps.textReps.text
return txtFieldReps
}
if index == 2 && indexPath.section == 1 {
let btnLog = tableView.dequeueReusableCellWithIdentifier("Button Log", forIndexPath: indexPath) as! ButtonLogWorkoutCustomCell
btnLog.btnLogExercise.addTarget(self, action: #selector(AddLogViewController.buttonClicked(_:)), forControlEvents: UIControlEvents.TouchUpInside)
// kg = txtFieldReps.textReps.text
return btnLog
}
if indexPath.section == 2 {
let loggedExerciseInformation = tableView.dequeueReusableCellWithIdentifier("Logged Exercise", forIndexPath: indexPath) as! LoggedExerciseCustomCell
return loggedExerciseInformation
}
let noCell = tableView.dequeueReusableCellWithIdentifier("Button Log", forIndexPath: indexPath)
return noCell
}
func buttonClicked(sender:UIButton) {
let button = sender as UIButton
if let superview = button.superview {
if (superview.superview as? ButtonLogWorkoutCustomCell) != nil {
try! LogManagerDAO.sharedInstance.realm.write({
exercise?.loggedKg = 4//Int(txtKG.text!)!
exercise?.loggedReps = 4//Int(txtReps.text!)!
log!.addExerciseToLog(exercise!)
loadLoggedExercise()
tableView.reloadData()
})
}
}
}

If you just want the text of that textField than you can use delegate method of UITextField like this, first declare two instance var for that 2 textField's value
var strKG: String = ""
var strReps: String = ""
Now set delegate with textField in cellForRowAtIndexPath
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let index = indexPath.row
if indexPath.row == 0 && indexPath.section == 0 {
let exerciseName = tableView.dequeueReusableCellWithIdentifier("Exercise Name", forIndexPath: indexPath) as! LoggedExerciseNameCell
exerciseName.lblExerciseName.text = self.exercise?.name
return exerciseName
}
if index == 0 && indexPath.section == 1 {
let txtFieldKg = tableView.dequeueReusableCellWithIdentifier("Text KG", forIndexPath: indexPath) as! KgCustomCell
txtFieldReps.textField.tag = index
txtFieldKg.textField.delegate = self
return txtFieldKg
}
if index == 1 && indexPath.section == 1 {
let txtFieldReps = tableView.dequeueReusableCellWithIdentifier("Text Reps", forIndexPath: indexPath) as! KgRepsCustomCell
txtFieldReps.textField.tag = index
txtFieldReps.textField.delegate = self
return txtFieldReps
}
if index == 2 && indexPath.section == 1 {
let btnLog = tableView.dequeueReusableCellWithIdentifier("Button Log", forIndexPath: indexPath) as! ButtonLogWorkoutCustomCell
btnLog.btnLogExercise.addTarget(self, action: #selector(AddLogViewController.buttonClicked(_:)), forControlEvents: UIControlEvents.TouchUpInside)
// kg = txtFieldReps.textReps.text
return btnLog
}
if indexPath.section == 2 {
let loggedExerciseInformation = tableView.dequeueReusableCellWithIdentifier("Logged Exercise", forIndexPath: indexPath) as! LoggedExerciseCustomCell
return loggedExerciseInformation
}
let noCell = tableView.dequeueReusableCellWithIdentifier("Button Log", forIndexPath: indexPath)
return noCell
}
Now add delegate method of UITextField
func textFieldDidEndEditing(textField: UITextField) {
if(textField.tag == 0) {
self.strKG = textField.text
}
else {
self.strReps = textField.text
}
}
Now just use this two string object in your button action method.
