系统：os x 10.10.5
cocos2d-x 3.6
xcode 7.0
之前打开过cocos2d 项目自带的 tests 工程。不知道现在为何打不开了。
编译项目 cpp-tests iOS
iPhone 6模拟器
报一下错误：
‘setContentScaleFactor’ overrides a member function but is not marked ‘override’
‘getContentScaleFactor’ overrides a member function but is not marked ‘override’
‘isRetinaDisplay’ overrides a member function but is not marked ‘override’
‘getEAGLView’ overrides a member function but is not marked ‘override’
‘init’ overrides a member function but is not marked ‘override’
我下载了 cocos2d-x 3.8 同样打开 tests 工程会报一个错误。
(null): In /Users/wjw/Library/Developer/Xcode/DerivedData/cocos2d_tests-cakukimplaunhngzakivmzjrmzjz/Build/Products/Debug-iphonesimulator/libcocos2d iOS.a(ftbase.ios8_x86_64.o), building for iOS simulator, but linking in object file built for OSX, for architecture x86_64
貌似说我的工程是要用模拟器运行，但是运行时自动在系统上运行，所以不通过。
请教各位如何解决啊
