Set args in -(id)init

is possible pass an args on an init method? I'm working with UITableViewController classes and UINavigatorController, when I push a new view whit:

[self.navigationController pushViewController:[[Class alloc] init] animated:YES];

I would also pass a string to that controller, is it possible?

It is not only possible, but it is normal and very common. In fact, it is quite common to have multiple initializers in classes where each initializer has a different combination of args, allowing you to initialize a class in different ways.

As you find yourself creating more than one initializer for a class, you should be sure to follow the best practices for making one initializer the "designated initializer". Here is a link to an article that demonstrates the principle of designated initializers.

Sure, just define your own initializer for your view controller subclass:

- (id)initWithStyle:(UITableViewStyle)style andSomeParameter:(NSString *)param
{
    if (self = [super initWithStyle:style]) {
        myInstanceVariable = [param retain];
    }
    return self;
}

(This is for a subclass of UITableViewController.)
