推荐答案
好的，我有一个完美的答案给你！
Alright, I have got a perfect answer for you!
这是代码：
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence {
// a buddy went offline/online
NSString *presenceType = [presence type]; // online/offline
NSString *myUsername = [[sender myJID] user];
NSString *presenceFromUser = [[presence from] user];
if (![presenceFromUser isEqualToString:myUsername]) {
if ([presenceType isEqualToString:@"available"]) {
[_chatDelegate newBuddyOnline:[NSString stringWithFormat:@"%@@%@", presenceFromUser, kHostName]];
NSLog(@"presence user is %@",presenceFromUser);
}
else if ([presenceType isEqualToString:@"unavailable"]) {
[_chatDelegate buddyWentOffline:[NSString stringWithFormat:@"%@@%@", presenceFromUser, kHostName]];
NSLog(@"presence user is invisible %@",presenceFromUser);
}
else if ([presenceType isEqualToString:@"subscribe"]) {
[_chatDelegate newBuddyOnline:[NSString stringWithFormat:@"%@@%@", presenceFromUser, kHostName]];
NSLog(@"presence user wants to subscribe %@",presenceFromUser);
}
}
}
我已经为您提供了完整的DidReceivePresence方法代码，以便您更好地理解。
I have provided you with the complete code of DidReceivePresence method for your better understanding.
现在让我用代码解释一下。如果你注意到else if条件我正在比较我们收到的值（元素）。因此，当我将字符串作为订阅时（当用户发送朋友请求时），您只需要在tableview好友列表中添加该特定用户。
Now let me explain you with the code. If you notice in the else if condition I'm comparing the value (element) which we are receiving. So when I get the string as Subscribe (when the user sends the friend request), you just need to add that particular user in your tableview buddy list.
您可以获得来自presenceFromUser的用户名。
You can get the username from "presenceFromUser".
