Sum data from several textfields to a label

@@rz · 02-13-2010, 08:07 AM

I'm trying to sum the integers from five UITextFields and post them to a UILabel.

This is the code I have tried. It works to begin with, then it start to mess up! Sometimes it doesent work at all!! Really weird!

int val = [textfield1.text intValue]
val = val+[textfield2.text intValue];
val = val+[textfield3.text intValue];
val = val+[textfield4.text intValue];
val = val+[textfield5.text intValue];

NSString *labelStr = [[NSString alloc] initWithFormat:@"%i", val];

label.text = labelStr;[/b]

Something wrong with the code?? Alternatives maybe? Greatful for all answers!

No nothing wrong with the code. You have to be more precise in the description of your problem if you want help. "Starts to mess up"? How?

Yes you are right. Really bad explenation. The code runs and builds just fine but it don't add right. The number showed on the label is wrong almsot every time!

Then you'll have to debug line by line.

What do you mean? Please explain.

Either yourself or somebody knowledgabe needs to build&debug the app and step through the code to see where the error lies. I can offer to do this for you , but I charge 75 Euros per Hour.

Is there no alternative to my current code to add values between textfields?

No.

Code:

int val = [textfield1.text intValue] + [textfield2.text intValue] + [textfield3.text intValue] + [textfield4.text intValue] + [textfield5.text intValue];

This?

@@rz · 02-14-2010, 07:16 AM

Same result..

ZunePod · 02-14-2010, 07:22 AM

NSLog all of the [textfield1.text intValue] things.

I'm sorry, but I dont't know how to do that. I would appreciate if you could explaine. Thanks

ZunePod · 02-14-2010, 08:06 AM

I'm assuming integers here?

Code:

NSLog(@"%i, %i, %i, %i, %i", [textfield1.text intValue], [textfield2.text intValue], [textfield3.text intValue], [textfield4.text intValue], [textfield5.text intValue]);

@@rz · 02-14-2010, 08:16 AM

Yes only integers!

Is this a way to diagnose my textfields, or is it a way to calculate?

ZunePod · 02-14-2010, 08:17 AM

No, this is checking what's happening with the numbers, look in your Console to see what the output is, and see if the numbers match what you put into the UITextFields.

Actual numbers showed in simulator 4 2 2 4 0

So in the textfield you put 4 2 2 4 0?

I think your linking something wrong, or you have a - somewhere.

Thank you for your time. I solved it by using a if formula instead.
