iOS How do I call a function with float return type?

[Jules2010]

Heres my function which xcode likes.

- (float) getLength:(NSString *)str
{
	float ret = 0.0;
	
	return ret;
}

Heres the calls I've tried to that function

lbl.text = self.getLength:@"1";
lbl.text = [NSString stringWithFormat:@"%i. ", self.getLength:@"1"];

I've tried similar variations but xcode doesn't like it.

I get this error.
error: request for member 'getLength' in something not a structure or union

Help!

TIA

The . syntax can only be used for properties. You have defined a method (not a function) so have to make a call to a method.

[self getLength:@"1"];

Also I do not expect that setting the text property of a label (which is a NSString) to a float would work.

I suggest you need to stop writing code and sit down with the Objective-C Introduction and cup of coffee/tea/beer.

Thanks.

I have gone through a short study book course, but its been lacking in some areas, but your right I need to find the time to study further. Good link, wish I'd had that sooner.
