How do I convert a string to a float in Objective-C?
I am trying to multiply a couple of strings I am getting back from JSON:
float subTotal = [[[[purchaseOrderItemsJSON objectAtIndex:i] objectAtIndex:j] objectForKey:@"Price"] floatValue];
NSLog(@"%@", subTotal);
This gives me: (null)
in the console. I know that there is a valid string coming out of that array because I am already using it to display its value in a label.
your_float = [your_string floatValue];
EDIT:
try this:
NSLog(@"float value is: %f", your_float);
