How to detect text view begin editing and end editing in swift 3 , Asks the delegate if editing should begin in the specified text view. func textViewShouldEndEditing(UITextView) -> Bool. Asks the delegate if editing should stop� Sourav Gupta's solution partially worked for me however it had a few pitfalls, namely that it didn't correctly call the target code if the editing happened in the middle of the text body (for example: writing a bunch of text, moving the cursor to the middle and then hitting return three times) as well as handling insertion events like pasting and text correction.

You could also implement the UITextViewDidChange delegate methods. I use the code below in my app for taking quick notes. Whenever the user has entered a character, the observer catches this from the notification center and calls the saveText method.

Here's how:

Add this line to the viewDidLoad method:

[NSNotificationCenter.defaultCenter addObserver:self selector:@selector(textViewDidChange:) name:UITextViewTextDidChangeNotification object:nil];

and these lines at the appropriate place in your code (like in the section that handles the text view delegate methods. TIP: Use pragma marks for this (#pragma mark - TextView Delegate Methods):

- (void)textViewDidChange:(UITextView *)textView{

    NSLog(@"textViewShouldEndEditing"); // Detect in log output if the method gets called
    [self saveText:nil]; // Call any method you like

}

use the delegate and use:

}

textViewShouldEndEditing(_:), A common idiom for a UITextView is to "end editing when the user touches anywhere outside the text field. This property holds the text position for the beginning of the document. Gets the UIBezierPath to be used for collision detection. Doing so causes the text view object to end the current editing session (with the delegate object’s consent) and hide the keyboard. The appearance of the keyboard itself can be customized using the properties provided by the UIText Input Traits protocol. Text view objects implement this protocol and support the properties it defines.

txtviewaddress.text="Address"

txtViewAddress.TextColor = UIColor.LightGray;
txtViewAddress.ShouldBeginEditing += (textView) =>
        {
 txtViewAddress.Text = "";
            txtViewAddress.TextColor = UIColor.Black;
            return true;
};
txtViewAddress.ShouldEndEditing += (textView) =>
        {
            if (textView.Text == "")
            {
                txtViewAddress.Text = " Address";
                txtViewAddress.TextColor = UIColor.LightGray;

            }
            return true;
