1.真機
將libstdc++.6.0.9.tbd文件拷貝到以下路徑：
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib
2.模擬器
將libstdc++.6.0.9.tbd文件拷貝到以下路徑：
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib
完成上述操作，真機可以運行，但是模擬器還會報錯：
Reason:no suitable image found. Did find: /usr/lib/libstdc++.6.dylib : mach-o, but not builtforiOS simulator
====================模擬器還需添加以下文件=====================
將libstdc++.6.0.9.dylib，libstdc++.6.dylib，libstdc++.dylib文件拷貝到以下路徑：
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib
