我的应用程序在一个单独的线程中运行一个网络任务——它从我的服务器获取数据,对其进行处理并持续显示结果。当我在一个线程中只有一个这样的网络连接时,这很好用。但是,如果我用类似的网络任务运行第二个线程,第二个工作正常,但第一个停止响应。我的班级安排网络进程的代码如下。关于这里可能出了什么问题的任何想法?
NSThread * nThread;
- (NSThread *)networkThread {
nThread = nil;
nThread =
[[NSThread alloc] initWithTarget:self
selector:@selector(networkThreadMain:)
object:nil];
[nThread start];
DLog(@"thread: %@, debug description: %@", nThread, nThread.debugDescription);
return nThread;
}
- (void)networkThreadMain:(id)unused {
do {
[[NSRunLoop currentRunLoop] run];
} while (YES);
}
- (void)scheduleInCurrentThread:(id)unused
{
[inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop]
forMode:NSRunLoopCommonModes];
[outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop]
forMode:NSRunLoopCommonModes];
}
-(BOOL) connectWithError:(NSString **) e
{
CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"127.0.0.1", [server port], &readStream, &writeStream);
inputStream = (__bridge NSInputStream *) readStream;
outputStream = (__bridge NSOutputStream *) writeStream;
[inputStream setDelegate:self];
[outputStream setDelegate:self];
[self performSelector:@selector(scheduleInCurrentThread:)
onThread:[self networkThread]
withObject:nil
waitUntilDone:YES];
[inputStream open];
[outputStream open];
}
