The coque samsung s6 fille ado original class is called the superclass coque pour samsung s8 plus and the subclass gets all the code in the superclass. You can also add additional code to the coque samsung s7 disney coque iphone 6 subclass. Programmers do this all coque samsung galaxy s6 edge femme the time which creates a hierarchy like the graphic at the top of this page.The Super And Self KeywordsIf you haven’t yet groked the relationship between classes coque iphone 5 and objects the details of this can get confusing. For instance, take a look at the init coques iphone xs max override that you get from Xcode’s code library:self = [super init];return self;NOTE I’m assuming you know about how coque samsung note 4 marbre to create classes in Objective C here.While both keywords objects created from the class self references the properties and methods defined in the current class definition while super references coque iphone 8 plus gess the properties and methods defined in the coque iphone 7 8 plus superclass definition.Objects And ClassesLet’s take another look at that init override so we can see the context where we usually see this function.return coque samsung s7 edge seatle 0;Here’s the English version samsung galaxy s6 coque fleur of the code above: we defined a class named MyClass which is a subclass of the coque pour samsung galaxie s5 NSObject class.

After all, when you want an object to behave differently you must make changes so rewrite the class definition. So that’s pretty natural.
