真实的iPhone设备上是否有类似于“getStreamsToHost”的东西？

3

我想使用苹果的示例代码将NSOutputStream写入服务器：


NSURL *website = [NSURL URLWithString:str_IP];
NSHost *host = [NSHost hostWithName:[website host]];
[NSStream getStreamsToHost:host port:1100 inputStream:nil outputStream:&oStream];
[oStream retain];
[oStream setDelegate:self];
[oStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[oStream open];

这些代码在iPhone模拟器上运行良好，但是当我将其构建到实际设备时，出现了两个警告。问题在于：

1）类NSHost不属于iphone os库

2）无法找到getStreamsToHost

有没有替代方法或类可用于实际设备？

由于CFWriteStream与NSOutputStream之间是toll-free bridged，因此您可以使用CFStreamCreatePairWithSocketToHost来获取您的流配对：

CFReadStreamRef readStream = NULL;
CFWriteStreamRef writeStream = NULL;
CFStreamCreatePairWithSocketToHost(kCFAllocatorDefault, (CFStringRef)host, port, &readStream, &writeStream);
if (readStream && writeStream) {
    CFReadStreamSetProperty(readStream, kCFStreamPropertyShouldCloseNativeSocket, kCFBooleanTrue);
    CFWriteStreamSetProperty(writeStream, kCFStreamPropertyShouldCloseNativeSocket, kCFBooleanTrue);

    inputStream = (NSInputStream *)readStream;
    [inputStream retain];
    [inputStream setDelegate:self];
    [inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
    [inputStream open];

    outputStream = (NSOutputStream *)writeStream;
    [outputStream retain];
    [outputStream setDelegate:self];
    [outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
    [outputStream open];
}

if (readStream)
    CFRelease(readStream);

if (writeStream)
    CFRelease(writeStream);
