I'd recommend you carefully read everything about background sessions and tasks in Apple's URL Loading System Programming Guide, particularly the section

问题 I am trying to learn Core Foundation with C/C++. I use JetBrains CLion that uses CMAKE. The problem is - I dunno how to include proper static libraries in C/C++ Makefile project on Mac. I need to link static library CFNetwork to my project in order to fix linking problems. Could you give me a quick hint?

问题 When I open my application after a while, I received log: 440: CFNetwork internal error (0xc01a:/BuildRoot/Library/Caches/com.apple.xbs/Sources/CFNetwork/CFNetwork-758.4.3/Loading/URLConnectionLoader.cpp:289) It has never been out in the past. My project uses a network library AFNetworking and CocoaAsyncSocket. Why does it occur and how to fix it? 回答1: I solved my situation, it is not AFNetwork's issue, I use a invalid SSL certification and SDWebImage, when use the option

问题 CFNetworkCopyProxiesForAutoConfigurationScript is Apple's native API, defined in CFNetwork framework.Whenever I call this API many memory leaks are left by this API and they keep on piling with each call to this API.I found it using "Instruments" and "View Memory Graph Heirarchy" option too. At the end it crashes due to memory issues. Below is the sample code that I am running. CFErrorRef err = NULL; NSString *strURL = @"http://www.google.com"; CFStringRef tempPacdata = CFStringCreateCopy

问题 My iOS device logs (on simulator and real devices) was filled with a couple dozen lines of the following error spam: CFNetwork internal error (0xc01a:/BuildRoot/Library/Caches/com.apple.xbs/Sources/CFNetwork_Sim/CFNetwork-758.0.2/ProjectRuntime/CFNetworkInternal.h:478) Why am I seeing these, and how do I get rid of them? 回答1: Turns out this was due to an incorrect setup in my Info.plist's NSAppTransportSecurity. Make sure that for each of the NSExceptionDomains you use, the subfields of the
