ios语音输入崩溃

　　游戏中任何可以输入的地方，只要调用语音输入，必然会导致app崩溃，解决方法如下：

　　ok, so essentially the gist of it is that siri wants gl context and to be rendered alongside your view. So you need to play nice with it.
first of all in Classes/Unity/EAGLContextHelper.h
add forward declaration for

struct UnityDisplaySurfaceBase;

and then inside class EAGLContextSetCurrentAutoRestore add constructor:

EAGLContextSetCurrentAutoRestore(UnityDisplaySurfaceBase* surface);

so it looks like that

struct UnityDisplaySurfaceBase;

<...>

class

EAGLContextSetCurrentAutoRestore

{

public:

   EAGLContext* old;

   EAGLContext* cur;

   EAGLContextSetCurrentAutoRestore(EAGLContext* cur);

   EAGLContextSetCurrentAutoRestore(UnityDisplaySurfaceBase* surface);

   ~EAGLContextSetCurrentAutoRestore();

};

then in Classes/Unity/EAGLContextHelper.mm
add

#include "UnityRendering.h"

and implementation for new ctor

EAGLContextSetCurrentAutoRestore::EAGLContextSetCurrentAutoRestore(UnityDisplaySurfaceBase* surface)

  : old(surface->api == apiMetal ? nil : [EAGLContext currentContext]),

   cur(surface->api == apiMetal ? nil : ((UnityDisplaySurfaceGLES*)surface)->context)

{

   if (old != cur)

     [EAGLContext setCurrentContext:cur];

}

Afterwards you just need to go to Classes/UnityAppController+Rendering.mm and add

EAGLContextSetCurrentAutoRestore autorestore(GetMainDisplaySurface());

to

static void UnityRepaintImpl(bool forced)

so it looks like this

static void UnityRepaintImpl(bool forced)

{

   @autoreleasepool

   {

     EAGLContextSetCurrentAutoRestore autorestore(GetMainDisplaySurface());

     Profiler_FrameStart();

<...>

again, i cannot even build 4.x now, so you need to use c/objc knowledge to fix possible compilation errors (if i forgot to mention some incudes or smth)
