iOSでソケット接続を実装しました。iOSはソケット接続を使用してデータを送信します
私は何をしたいことは、接続されたデバイスへのデータの文字列を送信することです... （私は誰かが私のデバイスに送信するときにデータを受信することができています）私はこのコードを試してみましたが、データが他に受信なっている 私のアプリを閉じると、
- (IBAction)connectToServer:(id)sender {
NSLog(@"Setting up connection to %@ : %i", _ipAddressText.text, [_portText.text intValue]);
CFStreamCreatePairWithSocketToHost(kCFAllocatorDefault, (__bridge CFStringRef) _ipAddressText.text, [_portText.text intValue], &readStream, &writeStream);
messages = [[NSMutableArray alloc] init];
[self open];
}
- (void)open {
NSLog(@"Opening streams.");
outputStream = (__bridge NSOutputStream *)writeStream;
inputStream = (__bridge NSInputStream *)readStream;
[outputStream setDelegate:self];
[inputStream setDelegate:self];
[outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[outputStream open];
[inputStream open];
_connectedLabel.text = @"Connected";
}
- (void)stream:(NSStream *)theStream handleEvent:(NSStreamEvent)streamEvent {
NSLog(@"stream event %lu", streamEvent);
switch (streamEvent) {
case NSStreamEventOpenCompleted:
NSLog(@"Stream opened");
_connectedLabel.text = @"Connected";
break;
case NSStreamEventHasBytesAvailable:
if (theStream == inputStream)
{
uint8_t buffer[1024];
NSInteger len;
while ([inputStream hasBytesAvailable])
{
len = [inputStream read:buffer maxLength:sizeof(buffer)];
if (len > 0)
{
NSString *output = [[NSString alloc] initWithBytes:buffer length:len encoding:NSASCIIStringEncoding];
if (nil != output)
{
NSLog(@"server said: %@", output);
[self messageReceived:output];
}
}
}
}
break;
case NSStreamEventHasSpaceAvailable:
NSLog(@"Stream has space available now");
break;
case NSStreamEventErrorOccurred:
NSLog(@"error: %@",[theStream streamError].localizedDescription);
break;
case NSStreamEventEndEncountered:
[theStream close];
[theStream removeFromRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
_connectedLabel.text = @"Disconnected";
NSLog(@"close stream");
break;
default:
NSLog(@"Unknown event");
}
}
/* Sends data to other device */
- (IBAction) sendMessage {
NSLog(@"sendMessage");
NSString *response = [NSString stringWithFormat:@"msg:%@", _dataToSendText.text];
NSData *data = [[NSData alloc] initWithData:[response dataUsingEncoding:NSASCIIStringEncoding]];
NSLog(@"[data length] %lu",(unsigned long)[data length]);
[outputStream write:[data bytes] maxLength:[data length]];
}
私は間違いを犯していますか？
