Answer 1

You should not return NO in ...

-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text

otherwise it will not allow you to add text.

Edit: From TextView reference:

textView:shouldChangeTextInRange:replacementText: Asks the delegate whether the specified text should be replaced in the text view.

(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text

Parameters:

textView: The text view containing the changes.

range: The current selection range. If the length of the range is 0, range reflects the current insertion point. If the user presses the Delete key, the length of the range is 1 and an empty string object replaces that single character.

text: The text to insert.

Return Value: YES if the old text should be replaced by the new text; NO if the replacement operation should be aborted.

Answer 2

You must return YES in this delegate method, else no text whatsoever will be allowed in fields that you are the delegate of, like so:

-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {

    if([text isEqualToString:@"\n"]) {
        [m_CtrlTxtViewDescription resignFirstResponder];
        [self setViewMovedUp:NO];
        return NO;
    }    
    return YES;
}

shouldChangeTextInRange..., as the name suggests, is the method that the text view calls when text is added through the keyboard. Delegates are asked whether or not text should be added.
