ठीक है, मैंने उपरोक्त को एक श्रेणी में बदल दिया है जो काम करता है।
दिलचस्प बिट्स:
- श्रेणियाँ सदस्य चर नहीं जोड़ सकते। जो कुछ भी आप जोड़ते हैं वह वर्ग के लिए स्थिर हो जाता है और इस प्रकार ऐप्पल के कई यूआईटीएपीजेस्टर रिकॉग्नाइज़र द्वारा घिरा हुआ है।
- तो, जादू करने के लिए related_object का उपयोग करें।
- NSValue गैर वस्तुओं
के भंडारण के लिए
- एप्पल के
init विधि महत्वपूर्ण विन्यास तर्क होता है; हम क्या सेट किया गया है पर (नल, स्पर्श की संख्या, और क्या?
- की संख्या अनुमान कर सकता है लेकिन इस अभिशप्त है। तो, हम हमारे init विधि है कि mocks को बरकरार रखता है में एक प्रकार का शराबी।
हेडर फाइल तुच्छ है,। यहां कार्यान्वयन है
