Change your function definition to -
(NSString*)convertFunctionWithValues:(NSString*)....etc and just add
"return retVal;"
Also, its not really necessary but in the interest of good coding
practices you may want to consider passing an array (NSArray of
NSNumber or whatever) to -[convertValues
convertFunctionWithValues:ValueTwo:ValueThree:ValueFour:ValueFire:ValueSix:ValueSeven:ValueEight:Pecision
:] since as I'm sure you can tell that's quite the doozy of a
function name.
You also don't need the = @"" part from your NSString declaration.

Hi,
I've currently got a function of type void that works swimmingly in
the debugger. I now need to populate a text field with the value
of the generated string within the function. The function is
declared along the lines:
- (void)convertFunctionWithValues:(NSString *)valueOne ValueTwo:
(double)valueTwo ValueThree:(double)valueThree ValueFour:
(double)valueFour ValueFive:(NSString *)valueFive ValueSix:
(double)valueSix ValueSeven:(double)valueSeven ValueEight:
(double)valueEight Precision:(int)precision;
{
// Declarations here
NSString *retVal = @"";
// Calculations go here...
// Lots of them...
// We've got the result, now we want to return it
retVal = [NSString stringWithFormat:@"%c%c%i%i", retLet1,
retLet2,retFinalCalcA,retFinalCalcB];
}
How do I now return this string value? The initialisation and
calling is done via:
convertedValue = [[convertValues alloc] init];
valToBeDisplayed = [convertedValue
convertFunctionWithValues:valueOne ValueTwo:valueTwo
ValueThree:valueThree ValueFour:valueFour ValueFive:valueFive
ValueSix:valueSix ValueSeven:valueSeven ValueEight:valueEight
Precision:precision];
// Display returned value
self.valDisplayField.text = valToBeDisplayed;
[convertedValue release];
Also, according to your code at the bottom here, you want to return a
value from a METHOD not a function.
Mike.
Any ideas appreciated.
Thanks,
Stu
