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];
Any ideas appreciated.
Thanks,
Stu
