Delete characters from textfields,iphone
<p>I have textfield and having a number "1234567890"
now i have button, on tapping it, it should delete the the number from last.
like as in keyboard.
but one time tap, should delete one int at a time.
I dont want to delete whole number at once, it should just delete a single int, on every single click.</p>

<p>How can i implement it.
Suggestion are always appreciated</p>
