I need to know how I can access a particular UITextField within a UIView from the ViewController class.
The setup I have currently is that I have ViewController that is linked to a View in Storyboard. I have UIView in nib that has 3 UITextFields. I load the view up using the following code:
TextFieldView = UINib(nibName: "TextView", bundle: nil).instantiateWithOwner(nil, options: nil)[0] as! UIView
self.view.addSubview(TextFieldView)
I can get all three UITextField and their values using the following code:
for case let textField as UITextField in TextView!.subviews {
print(textField.text)
}
My issue is that how can I get the value of any one particular UITextField using some sort of identifier or a tag. Lets say I have 3 UITextFields named TextField1, TextField2, and TextField3 respectively. How do I get the value of TextField2?
If you want to find it by class then you can loop like as :
for view in self.view.subviews {
if let textField = view as? UITextField {
print(textField.text!)
}
}
If you want to find through tag then you can use viewWithTag
as described by @BalajiKondalrayal.
Set tag of text field as follows :
Select text field and set tag property.
@IBAction func getAllTextFromTextFields(sender: AnyObject) {
//Get All Values
for view in self.view.subviews {
if let textField = view as? UITextField {
print(textField.text!)
}
}
//Get One By One with Tag
if let txtField1 = self.view.viewWithTag(1) as? UITextField {
print(txtField1.text!)
}
}
Hope it help you.
Use viewWithTag option. Try this:
if let theTextField = self.view.viewWithTag(yourTagId) as? UITextField {
print(theTextField.text)
}
Objective-C :
UIView *view = [self.view.viewWithTag:YourTagId];
if([view isKindOfClass:[UITextField class]]
{ NSLog(@"%@", view.text);
}
