Question

I have some instance variables in my class that I’d want to be accessible anywhere. Like so:

@interface SomeObject : NSObject
{
    @public
        NSString *someString;
}
@end

@implementation SomeObject
@end

I can access the property from the instance using the -> syntax like below, as I would do in C++:

someObjectInstance->someString

Should I make a property for someString when all I want is for it to be accessible by the outside world? I would create a @property for someString in my interface and @synthesize it in my implementation, which would enable me to access it using the dot syntax.

Generally speaking, if you want to expose data, you should use properties. Making instance variables public is a bad idea in general.
