Change 'Return' button function to 'Done' in swift in UITextView

I would like to get rid of the "return" function of the keyboard while the user is typing, so there are no new lines, so instead I would like the 'return' key to function as 'Done' so it would hide the keyboard.

I am using a UITextView, that is editable, so the user is able to type their post, and post it to the main timeline, but since I have fixed cells, I don't want the user to be able to press 'return' and their post would be out of range of the timeline.

I found this that works with UITextField, but not with UITextView:

func textFieldShouldReturn(textField: UITextField!) -> Bool {
textField.resignFirstResponder() //if desired
return true
}


So I just wanted to know if there is a way to do that in a UITextView, or at least to be able to hide the keyboard if pressed return, instead of creating a new line.

You can set the return key type of the text field:

textField.returnKeyType = UIReturnKeyType.Done

Update You can definitely use the same approach to set the return key to "Done", as mentioned above. However, UITextView doesn't provide a callback when user hits the return key. As a workaround, you can try to handle the textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) delegate call, and dismiss the keyboard when you detect the input of a new line character:

func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool {
    if (text == "\n") {
        textView.resignFirstResponder()
    }
    return true
}
