Question

I have an NSMutableArray which returns me some object.
The object which I added had properties name,age.

now when I use these properties on the Object returned (obj.name or obj.age ),
Compiler says, no such member, use (->) instead of (.)

I understand that NSObject wont have these members and hence it wont understand the property.

But If i use setters, and getters as method ([obj name] or [obj age]) syntax instead of this properties, I dont get any errors.

But using property means calling a setter or getter only ?
ad Objective C is suppose to be dynamic language, right ?

Answer 1

That’s right – dot syntax is not supported in such case.

You need to cast a pointer to the actual class:

((MyObject*)[array objectAtIndex: 0]).name = @"Bill";
