Using an Objective-C function to set an integer

I have an Objective-C function as follows:

-(float)getModelTotal: (int)amount forSelector: (NSString*)selectorType;

I would like to perform the following steps in a different funciton:

float programFee = 1;

float token = [self getModelTotal: object.Alpha forSelector: object.Beta];
programFee += token;

object.Alpha is an integer and object.Beta is an NSString.

The function returns a float and I would like to add the result to a different float. When I invoke the function by sending a message to self, I get an error and rightfully so because the float is not self in this case.

To what receiver should I send this message?

That's not a function, it's a method. You should send the message to an instance of whichever class you declared the method on.

If you want a function, declare it C-style, but outside of the @implementation block.

Update: It seems like it's telling you Object.Alpha is really an NSNumber? Try:

float token = [self getModelTotal: [object.Alpha intValue] forSelector: object.Beta];

Ok, well, object.alpha is apparently an NSNumber, not an int.

So you should make the call something like this:

[self getModelTotal: [object.alpha intValue] forSelector:object.beta]
