今天，突然遇到这个问题，各种尝试都不能解决，把添加的代码全部注释也不行，
Failed to write value for key UMSocialOpCount in CFPrefsPlistSource<0x1700e6b00> (Domain: com.******.qqq, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null)): Path not accessible, switching to read-only
[User Defaults] attempt to set <private> for key in <private> in read-only (due to a previous failed write) preferences domain CFPrefsPlistSource<0x1700e6b00> (Domain: com.*******.qqq, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null))
后来找到一个方案，但是依然没有解决http://www.jianshu.com/p/e782104c3bc3，
