    मैं कुछ समय के लिए Google पर इसे खोज रहा हूं और कुछ भी नहीं आया हूं।

    मैं एक लाइब्रेरी का निर्माण कर रहा हूं, और यह लाइब्रेरी बहुत आसान और अधिक सहज होगी यदि मैं कस्टम गुणों को एप्पल के पूर्व निर्मित ऑब्जेक्ट्स, आईई से जोड़ दूं। NSString, UIImage, आदि।

    यदि गुणों को जोड़ना संभव नहीं है, तो अगला सर्वश्रेष्ठ क्या है?

    मैंने स्टैक ओवरफ्लो पर ऐसी ही चीज़ें देखी हैं, लेकिन उन सभी कस्टम वर्ड्स के लिए श्रेणियां हैं।

    धन्यवाद अग्रिम!

    आप संबंधित वस्तुओं चाहते हैं आप केवल श्रेणी का उपयोग करते हुए मौजूदा कक्षाओं में गुण जोड़ नहीं सकते हैं।

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
