f3a85ece4307a7b90816c34489d1ed2c8fd11baf. * remove win32 project files ref in template.json * add metal framework lnk ref into cpp template * test on iOS, and disable part cases * alBufferData instead of alBufferDataStatic for small audio file on Apple (#19227) * changes AudioCache to use alBufferData instead of alBufferDataStatic (also makes test 19 faster to trigger openal bugs faster) The original problem: CrashIfClientProvidedBogusAudioBufferList https://github.com/cocos2d/cocos2d-x/issues/18948 is not happening anymore, but there's still a not very frequent issue that makes OpenAL crash with a call stack like this. AudioCache::readDataTask > alBufferData > CleanUpDeadBufferList It happes more frequently when the device is "cold", which means after half an hour of not using the device (locked). I could not find the actual source code for iOS OpenAL, so I used the macOS versions: https://opensource.apple.com/source/OpenAL/OpenAL-48.7/Source/OpenAL/oalImp.cpp.auto.html They seem to use CAGuard.h to make sure the dead buffer list has no threading issues. I'm worried because the CAGuard code I found has macos and win32 define but no iOS, so I'm not sure. I guess the iOS version is different and has the guard. I could not find a place in the code that's unprotected by the locks except the InitializeBufferMap() which should not be called more than once from cocos, and there's a workaround in AudioEngine-impl for it. I reduced the occurence of the CleanUpDeadBufferList crash by moving the guard in ~AudioCache to cover the alDeleteBuffers call. * remove hack method "setTimeout" on audio * AutoTest works on iOS * support set ios deployment target for root project * enable all texture2d cases, since Jiang have fixed * add CCTextureUtils to xcode project file (#176) * add leak cases for SpriteFrameCache (#177) * re-add SpriteFrameCache cases * update template file json * Update SpriteFrameCacheTest.cpp * fix compiling error
