Question

I have a textView (tF1) that will be supplied with a numeric value by the user. I need to assign that to number to the int (n).

This is what I came up with:

#import "blabla.h"

int n;

....

[tF1 resignFirstResponder];
n = (int)[tF1 text];
NSLog(@"n is, %d",n);

My problem is that the int value comes out to be a vary large number, like 82296768, for a textview value of 4.

Any and all help would be greatly appreciated! 🙂

SOLVED

changed line,
n = (int)[tF1 text];

to,
n = [[tF1 text] initValue];

Answer 1

NSString has a method intValue that you should be using:

n = [[tF1 text] intValue];

From the documentation for NSString, the other numeric values you can retrieve are:

– doubleValue
– floatValue
– intValue
– integerValue
– longLongValue
– boolValue

To invert this process, that is to add a numeric value as a string, you can use the NSString method -stringWithFormat:, e.g.

[tF1 setText:[NSString stringWithFormat:@"%d", someIntValue]];
