NSTextField to uint16_t

I have a text field in my iPhone app and I want to convert what the user enters and convert that to a uint16_t. How can I do that?

The text box will only be their for entering numb开发者_如何学运维ers.

This should work:

uint16_t integer = (uint16_t)[myTextField.text integerValue];

This will take the text field's text, convert it to an integer and cast it to a uint16_t. Note that it will not work if the user enters a value bigger than 65,535 (or less than 0 for that matter).
