Question

In C# I can add getters anIntVariable = someMethod1() + someMethod2()... but in Objective-C, I a get a warning, “Implicit Declaration of function ‘someMethod1’is invalid in c99. What is the equivalent way to do arithmetic with methods? Thanks.

Answer 1

You can do this in Objective C.

NSInteger myNumber = [self method1] + [self method2]; // myNumber is 3

Where method1 & method2 might be implemented like:

- (NSInteger)method1 {
     return 1;
}

- (NSInteger)method2 {
     return 2;
}
