Question

I have an object that I want to segue between two MVC’s. Do the properties in the first MVC get segued along with the object or is it only the methods. IE: if I have an int property with the value 5 and then perform a segue passing the object. Will my new MVC have access to this property and the value 5? or will it only have access to the passed objects methods?

Answer 1

Properties are not passed or set on the destination viewController in a segue. If you want your destination viewController to use an object (instance of a class) or some simple variable, you must define that property in your destination viewController class and then set it in prepareForSegue: For example, in the code bit below, the destination viewController has a property ‘sectionToShow’ and the setter for that property is being called.

Another approach is to define a delegate for the destination viewController and set it in the same way. Then the destination viewController can call the methods and access the properties of the delegate.

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{

    NSString* identifier = segue.identifier;

    if([identifier isEqualToString:@"userGuideSegue_home"]){
        UserGuideViewController* vc = segue.destinationViewController;
        [vc setSectonToShow:@"Home Screen"];
    }
}
