How do I manipulate textfield variables within an iPhone app? I want to have three text fields, formatted to numbers only, and be able to manipulate the data when I press different buttons.
Any help would be appreciated!

UITextField objects have a ‘text’ property of type NSString that can be read and written. Keep a reference to the text fields, and when a button is pressed, update the field’s text property with a new NSString to change its contents. If the text fields are not directly editable by the user, you may want to use UILabel instead, which is basically just a non-editable text field (and which also has a read/write ‘text’ property).
