我正在使用gamekit在nsdictionary中发送nsnumber . 当我对字典进行NSlog时，数字是可以的，但是当我尝试获得NSNumber时，它总是（null） .
NSMutableDictionary *dict = [NSKeyedUnarchiver unarchiveObjectWithData:data];
NSNumber *receivedHostNum = (NSNumber*)[dict objectForKey:@"h"];
if (gameStarted == NO){
NSLog(@"%@",dict);
NSLog(@"My Num:%i",[hostNum intValue]);
NSLog(@"%@",receivedHostNum);
NSLog(@"Recieved Num:%i",[receivedHostNum intValue]);
if ([hostNum intValue]>[receivedHostNum intValue])
NSLog(@"You are host");
else
NSLog(@"You are client");
}
这是日志：
2012-08-21 14:34:06.067 PeerPicker[6667:c07] {
"-589267889" = h;
}
2012-08-21 14:34:06.068 PeerPicker[6667:c07] My Num:-2142897577
2012-08-21 14:34:06.068 PeerPicker[6667:c07] (null)
2012-08-21 14:34:06.069 PeerPicker[6667:c07] Recieved Num:0
2012-08-21 14:34:06.069 PeerPicker[6667:c07] You are client

我想你已经把你的号码放错了 . 您的日志显示：
它应该是：
在构造阵列或存储阵列时，您已将键和对象反转 .
