获取在线用户列表 PubNub 始终为零 Objective C

Question

我的问题与相同，但似乎没有有用的答案。

I registed client with Pub & Sub key with Presence = YES

I subsrcibed to "My channel" and could send msg to it

I used debug console in PubNub admin to create 2 others clients, I could send msg together

I enable Presence in Admin (http://prntscr.com/iyv7b1)

I get list user that subscribe "My channel" by function:

[client hereNowForChannel:@"My channel" withVerbosity:PNHereNowState completion:^(PNPresenceChannelHereNowResult *result, PNErrorStatus *status)
 {
     if (!status) {

     }
     else {
         UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Couldn't get list of user." delegate:nil cancelButtonTitle:@"Close" otherButtonTitles:nil];

         [alert show];
     }
 }];

我试着改变

PNHereNowState -> PNHereNowUUID -> PNHereNowOccupancy

但是我的结果总是NIL。

任何人帮助我，请

我找到了问题的答案，希望对需要的人有所帮助

[client hereNowForChannel:client.globalChannel withCompletion:^(PNPresenceChannelHereNowResult *result, PNErrorStatus *status)
 {
     if (!status) {
         PNPresenceChannelHereNowData *data = result.data;
         if (data) {
             NSArray *list = [data uuids];

         }
     }
     else {

     }
 }];

属性data，如果还没有访问它，它不会被设置值，所以我调用了PNPresenceChannelHereNowData *data = result.data; 它有数据。
