更新推送的时候崩溃 [EMPushOptions(Private) toCorePtrWithoutIgnoredGroupIds]

出现问题部分的代码如下

EMPushOptions *option =    [[EMClient sharedClient] getPushOptionsFromServerWithError:nil];



option.displayStyle = EMPushDisplayStyleMessageSummary;



EMError *error=[[EMClient sharedClient] updatePushOptionsToServer];

具体表现是当环信服务器连接不上或者出现问题时，线上大规模的Crash。平时也有零星的Crash。
Bugly收集到的崩溃日志如下

现将代码修改为

EMError *err=nil;

EMPushOptions *option =  [[EMClient sharedClient] getPushOptionsFromServerWithError:&err];

option.displayStyle = EMPushDisplayStyleMessageSummary;



if(err)

    {

        //上报错误

        return;

    }

EMError *error=[[EMClient sharedClient] updatePushOptionsToServer];

不知道是否可以解决此问题。谢谢。
