Ironsource sdk在Unity 2019.3.x下代碼過時bug

報錯：Assets\IronSource\Editor\FacebookSettings.cs(18,48): error CS0619: ‘PBXProject.GetUnityTargetName()’ is obsolete: ‘This function is deprecated. There are two targets now, call GetUnityMainTargetGuid() - for app or GetUnityFrameworkTargetGuid() - for source/plugins to get Guid instead of calling to TargetGuidByName(GetUnityTargetName()).’

原來代碼：

可以把代碼修改爲：

#if UNITY_2019_3_OR_NEWER
string targetId = project.GetUnityFrameworkTargetGuid();
#else
string targetId = project.TargetGuidByName(PBXProject.GetUnityTargetName());
#endif
