I have a simple UITableViewController with 6 rows, each with a UITextField. I want to be able to click on each row and have the keyboard apply to each. Everything works, except for some reason I have to click on each row twice to get the responder to make the next UITextField active. I put in UITextFieldDelegate printouts and the order of their actions seems wrong. Each of the TextFields has been tagged 0 - 5. When I select the first, there is no problem, the keyboard comes up, I enter something. My printout is:
textFieldShouldBeginEditing tag: 0
textFieldDidBeginEditing tag: 0
Then I select the next row (without hitting Done in the keyboard) and the printout is this:
textFieldShouldBeginEditing tag: 1
textFieldShouldEndEditing tag: 0
textFieldDidEndEditing tag: 0
Why is textFieldDidBeginEditing not being called?
Here is my code in case it helps:
class EstimateCell: UITableViewCell, UITextFieldDelegate {
@IBOutlet weak var estimateField: UITextField!
// callback to alert when user clicked "Done"
var doneTextFieldInput: ((cell: EstimateCell, newText:String?) -> Void)?
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
// self.selectionStyle = .None
estimateField.delegate = self
estimateField.clearsOnBeginEditing = true
// add a done button to the numberpad
addDoneButtonOnNumpad(estimateField)
// add some padding to the right margin
estimateField.layer.sublayerTransform = CATransform3DMakeTranslation(-20, 0, 0)
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
/**
Only allow 4 digits
*/
func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {
// only allow 4 digits max
guard let text = textField.text else { return true }
let newLength = text.characters.count + string.characters.count - range.length
let isMax4digits = newLength <= 5
return isMax4digits
}
func textFieldShouldBeginEditing(textField: UITextField) -> Bool {
print("textFieldShouldBeginEditing \(textField.tag)")
return true
}
func textFieldDidBeginEditing(textField: UITextField) {
textField.text = ""
print("textFieldDidBeginEditing \(textField.tag)")
}
func textFieldShouldEndEditing(textField: UITextField) -> Bool {
print("textFieldShouldEndEditing \(textField.tag)")
return true
}
/**
Called after the textfield resigns as the first responder
*/
func textFieldDidEndEditing(textField: UITextField) {
print("textFieldDidEndEditing \(textField.tag)")
doneTextFieldInput?(cell: self, newText: textField.text)
// textField.resignFirstResponder()
}
func textFieldShouldReturn(textField: UITextField) -> Bool {
print("textFieldShouldReturn")
textField.resignFirstResponder()
return true
}
/**
Adds a toolbar with a Done button as an input accessory view to the given textfield. Calls
resignFirstResponder when Done is clicked.
*/
func addDoneButtonOnNumpad(textField: UITextField)
{
let keypadToolbar: UIToolbar = UIToolbar()
// add a done button to the numberpad
keypadToolbar.items=[
UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: textField, action: #selector(UITextField.resignFirstResponder)),
UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: self, action: nil)
]
keypadToolbar.sizeToFit()
// add a toolbar with a done button above the number pad
textField.inputAccessoryView = keypadToolbar
}
}
