Question

I am stuck with objective-c properties. What I need is to assign a write-only property for a variable, exactly the opposite of readonly, i.e the variable can have setMethod, but it should not have getMethod. I don’t know how to do it. answers with some code snippets are appreciated.

Answer 1

You can do something like:

@interface MyClass {
@private
int _var;
}

- (void)setVar:(int)newVar;
@end

@implementation MyClass
- (void)setVar:(int)newVar {
_var = newVar;
}
@end

Now you can access the variable var like a property that is write-only:

@implementation SomeOtherClass
...
MyClass c = [[MyClass alloc] init];
c.var = 3;
...
@end

And if you try to read the fake property the compiler will warning you.
