保持网络连接,同时保持不活跃状态?
原标题:Keeping iPhone network connections alive while in inactive state?

我正在开发一个连接聊天服务器的聊天客户。 当我收到任何民意通知(例如,SMS电文)时,Peter将 app子带入不活动状态——是巨大的。 我遇到的问题是,一旦通知被驳回,那一人就失去了所有网络联系。 我已经读到其他地方,但我不相信我所缺的是什么!

这里是我用来创建读写流的法典的幻灯。

- (void) initNetworkCommunication {

//set up read and write streams
CFReadStreamRef readStream;
CFWriteStreamRef writeStream;

//connect to host at this address and this port
CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"somewebsite.org", 3333, &readStream, &writeStream);

//open socket connection
inputStream = [(NSInputStream *)readStream retain];
outputStream = [(NSOutputStream *)writeStream retain];
[inputStream setDelegate:self];
[outputStream setDelegate:self];
[inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[inputStream open];
[outputStream open];
}

发送到背景时,网络连接也丢失。 我也想确定这一点,但现在的主要问题是使用户脱节的民意通知。

最佳回答

您在应用“应用:”方法时做了哪些工作? 您可以考虑中止联系,然后在接任者再次积极时恢复联系。 无论怎样,你都应以这种方法做一些事情。
