问题 I want to disable the "." key on the number pad after detecting that the user already has entered in one decimal point into the textfield.

问题 I have a UITableView tall enough that it necessitates scrolling. The top-most cell in the table contains a UITextField for the user to enter some text. The standard way to build this might be to create and add the text field and add it to a cell created or recycled in cellFOrRowAtIndexPath: However, this constant re-creation means that the text entered in the field is erased when the cell is scrolled out and back into view. The solutions I've found so far suggest using UITextField delegation
