    मैंने उसमें एक आवेदन किया ऐप लॉन्च होने पर मैं NSUserdefaults में कुछ वैरिएबस बचा सकता हूं लेकिन मैं यह करना चाहता हूं कि जब एप पृष्ठभूमि से बंद हो जाए तो उसे सभी NSUserdefaults मान को हटा देना चाहिए। मैं यह कैसे कर सकता हूँ। कृपया मेरी मदद करें।

    आईओएस पर, पृष्ठभूमि में होने पर आपका ऐप मिट जाता है जब कुछ भी नहीं कहा जाता है

    उस बिंदु पर जहां आप पृष्ठभूमि से अग्रभूमि से आगे बढ़ते हैं, आपको अपने ऐप के लिए जरूरी सारी जानकारी संग्रहीत करना चाहिए, जो कि अपरिवर्तित दिखने के लिए वापस आ जाता है अगर इसे मारे जाने और पुन: लॉन्च किया जाता है। ऐसा करके, आईओएस को अपने ऐप को पृष्ठभूमि में किसी भी समय मारने की स्वतंत्रता है। यह आवश्यक है क्योंकि आईओएस आपको उदाहरण के लिए मार देगा यदि इसे अन्य ऐप्स के लिए अधिक मेमोरी चाहिए; उस बिंदु पर फिर से अपना ऐप शुरू करने के लिए पूरी तरह उल्टा होगा

    लेकिन आप क्या कह रहे हैं यह इंगित करने के लिए लगता है कि आप चाहते हैं कि ऐप अलग ढंग से व्यवहार करे अगर पृष्ठभूमि में मारे गए ऐसा करना गलत बात है उपयोगकर्ता को कभी भी ध्यान न दें कि आपके ऐप को मार दिया गया था।

c++ - Cmake produces file extensions in static library archives -

I have recently switched to autotools to cement, since the limiter cross platform is better for development and what I saw When I build a stable library of my C ++ code, all the files inside .cpp.o is a suffix ar income tax PA8 / libgenericTZR.a genericTZR.cpp.o I have seen other libraries made by other tools and they do not do it, I'm not sure this is the realm And there is a bad thing, but how can I create static libraries without cpp file extension? This is my CMake file add_executable (PA8 ISP_Charges.cpp genericTZR.cpp genericTZR.h) set (LIBSRC genericTZR.c genericTZR.h) add_library (genericTZR shared $ {LIBSRC}) add_library (genericTZR shared $$ TARGET_OBJECTS: myObjects & gt;) install add_library (Generic TZR-static static $ {LIBSRC}) set_target_properties (Generic TZR-Static Properties OUTPUT_NAME $ install (TARGETS PA8 DESTINATION BIN) TARGETS GENICTZR GENERICTZR-STATIC DESTINATION lib) Installed (files "$ {PROJECT_BINARY_DIR} /PA8/genericTZR.h...

c# - XML - Serialize class - Some questions -

-
I have the idea of ​​serializing the properties of a class in an XML-file and then uploading this file to the server The reason for this is that I want to download this file again and read the serialized content. Then this kind of structure: file exists (myfile.xml) - & gt; Serialize the file in data from class (myclass.cs) - & gt; Upload file. Now the content may look something like this: Now the problem is, I do not know how to walk. I want the new data to be serialed in the next way, but it should be linked to that XML-file, not a new one. So I download this file and then I serialize the new data as an attachment so that it will look like this: And it should be repeated many times as I want: download file, serial new data and attach it together, then upload it again. Now, the second issue is, I want to read it. I also use XML-class for this. For the type of ultimate type, the data should be serialized, I set the square in which the assets are. But now,...
