ios - NSNotificationCenter calling methods from super class or subclass? -

-

मेरे पास एक दृश्य नियंत्रक है B जो A का उप-वर्ग है ए के देखें वेलअपेर में 

  [[NSNotificationCenter defaultCenter] में नामित एक अधिसूचना के लिए मैंने पंजीकृत किया है I AddObserver: स्वयं चयनकर्ता: @ सिलेक्टर (MyNotificaitonNameHandler :) नाम: kMyNotificaitonName ऑब्जेक्ट: शून्य];

मैंने MyNotificaitonNameHandler को देखने नियंत्रक A और B में लागू किया है जिसे विधि कहा जाएगा?

यह विशेष ऑब्जेक्ट पर निर्भर करता है। अगर आपने ए का एक उदाहरण बनाया है तो यह ए होगा और अन्यथा। चूंकि आपका बी क्लास MyNotificaitonNameHandler का कार्यान्वयन करता है और आपके पास B का उदाहरण है, तो यह बी शुद्ध OOP

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.)
