Quick Keyboard Question

lifeCoder45 · 07-31-2010, 12:17 PM

Hey guys, I have a UITextField, that uses UIKeyboardNumberPad. I'm using it to enter a dollar amount. So what I want is, when the user loads the view, the field has a value of 0.00. I have this done, but what I want now is, when the user pushes a number, it pushes it onto the amount, but maintains the .xx;

Like so:

Code:

Value: 0.00

Type 1

Value: 0.01

Type 5

Value: 0.15

Type 0

Value: 1.50

Type 5:

Value: 15.02

Backspace

Value: 1.50

Make sense? I'm guessing I probably need to do some string manipulation in one of the UITextField delegate methods?

Thanks!

Ok, so I've been looking into this, and I think NSFormatter may be what I need to get the job done. I've looked through the docs, but they are a little overwhelming!

My new question is, is there a setting I can set NSFormatter to to force the input number to an X.xx decimal, BUT without the user typing the '.'? What I want is for all of the numbers to be pushed to the right.

Like so:

Code:

User types '1';

Formatter, populate UITextfield with: 0.01;

User types '2';

Formatter, populate UITextfield with: 0.12;

User types '4';

Formatter, populate UITextfield with: 4.12;

User deletes '1';

Formatter, populate UITextfield with: 0.42;

etc?

Basically I want the user to enter a dollar amount, with cents, but I only want them to have access to the 0-9 numpad.

Thanks!
