iOS How do I get an absolute value from NSNumber

[John Baughman]

I am having trouble making this work...

cell.detailTextLabel.text = [NSString stringWithFormat:@"%ihrs West",[[statusInfo objectAtIndex:indexPath.row] unsignedIntValue]];

The object in the statusInfo array is an NSNumber. If it contains the value -2, I want the cell.detailText.text to display 2hrs West. Instead I am getting -2hrs West. I can't figure out how to get the absolute value of the integer stored in the NSNumber. I have tried a lot of different things, but the above code seems to me to be the way to do it. What am I doing wrong.

Get a signed int and use the abs function?

You could just do a dirty hack and multiply the value by -1 if the value is negative

OR

You could use the c abs function on the value from the from the row,

cell.detailTextLabel.text = [NSString stringWithFormat:@"%ihrs West",abs([[statusInfo objectAtIndex:indexPath.row] intValue])];

I think this should work.

thanks!! The abs function worked great.

I jumped into Objective-C never having done any c programming. I really need to take a time out and review what is available in c and how to use it in Cocoa.

Thanks again,
