Question

is it possible to format the .stringValue property of a NSString outlet without creating extra variables ??

@property (retain) NSString *myString;
@property (retain) NSString *myStringLabel;

–

@synthesize myString;
@synthesize myStringLabel;

myString.stringValue = myStringLabel.stringValue  

/* but I want to format it with %.0f
   so I don't get any fractional digits */

I am currently playing around with sliders and the values are of format 1.123312
I want to display only the leading number.

Assuming your input string is something that can be represented as a float :

formattedString = [NSString stringWithFormat:@"%2.0f", [inputString floatValue]];

or if you wanted to round the value instead :

formattedString = [NSString stringWithFormat:@"%i", round([inputString floatValue])];

I’m not sure why you would want to do this specifically on one line though?
