Question

Hi I am seeking some insight into storing text input into a variable. My task is to take five text inputs, store the numbers the user inputs, then do some fancy math with them to create a solution variable to display. However, within the SDK I am getting confused quickly on how to actually store these correctly. I can’t find much tutorials on this online, seeking gurus to help!

Pretty straightforward stuff.

Declare the variable:

 NSString *aString;

Then assign the string:

aString = someTextField.text;

If you’re going to need the string to stick around for any period of time beyond the method where you capture it, you might consider making it a property of the class:

@property(nonatomic, copy) NSString *aString;

That’s just for a string. If the user is inputting text that you want to treat as a number, you can do:

NSInteger userInputInteger = [someTextField.text intValue];
