ios - Prefixing the files to avoid symbol conflicts between external frameworks -

-

I'm using the two external structure in my IOS code. While both the Framework internally PLCrashReoprter using the framework, which is why I'm getting duplicate symbol errors.

Now a framework, i.e. the prefix of the file in the crash reporter framework, has the name / symbols attached. Code written to add the prefix names are given below: 

  #define PLCRASHREPORTER_PREFIX AcmeCo #ifdef PLCRASHREPORTER_PREFIX // We need two additional layers to make CPP option / / PLCRASHREPORTER_PREFIX Let's define. PLNS_impl2 (prefix, symbol) prefix ## signal # define PLNS_impl (prefix, symbol) PLNS_impl2 (prefix, symbol) #defined PLNS (symbol) PLNS_impl (PLCRASHREPORTER_PREFIX, symbol) #define PLCrashMachExceptionServer PLNS (PLCrashMachExceptionServer) #define PLCrashReport PLNS PLCrashReportApplicationInfo PLCrashReportBinaryImageInfo PLNS (PLCrashReportBinaryImageInfo) #define PLCrashReportExceptionInfo PLNS (PLCrashReportExceptionInfo)

now the error " comes Apple Mach-O linker error " 

  i386 undefined symbols of architecture: "_OBJC_CLASS _ $ _ AcmeCoPLCrashReport", refers: objc-class-ref.o   
 I've added the above all to the  nameSpace.h  file. 
 
 Please guide me as trying all possible things but no use. thank you in advanced!

You must similarly compiled again the same framework (all. Files) macro definition to modify it Can export and use symbol names.

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
