So,you are dealing with custom keyboard and of course you have your keyboard button's click functions,for example UIButton action for touch up inside. What you have to do is get characters on button press from uibutton's text and make string by appending every character. Hope this helps. — Syed Sadrul Ullah Sahad, Jan 17 '18 at 07:40

From button action get text and make string what you want.

NSString *someString;// Global
- (IBAction)characterButtonAction:(UIButton *)sender {
        someString = [someString stringByAppendingString:sender.titleLabel.text];
}

Or you can use [self.textDocumentProxy documentContextBeforeInput] to get the whole current string visible. This will return the string before cursor.
