CFStreamCreatePairWithSocketToHost 上的错误访问 exc_i386_gpflt答案

【问题标题】：bad access exc_i386_gpflt on CFStreamCreatePairWithSocketToHostCFStreamCreatePairWithSocketToHost 上的错误访问 exc_i386_gpflt
【发布时间】：2015-04-02 13:40:25
【问题描述】：

我正在尝试与我的服务器建立 TLS 连接，但它出错了

CFStreamCreatePairWithSocketToHost(kCFAllocatorDefault, str, 5555, &readStream, &writeStream);

exc_i386_gpflt 访问不正确。我该如何解决？

完整代码

CFReadStreamRef readStream = NULL;
CFWriteStreamRef writeStream = NULL;
CFStringRef str = (CFStringRef)"127.0.0.1";
CFStreamCreatePairWithSocketToHost(kCFAllocatorDefault, str, 5555, &readStream, &writeStream);
if (readStream && writeStream) {
    CFReadStreamSetProperty(readStream, kCFStreamPropertyShouldCloseNativeSocket, kCFBooleanTrue);
    CFWriteStreamSetProperty(writeStream, kCFStreamPropertyShouldCloseNativeSocket, kCFBooleanTrue);

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

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

if (readStream)
    CFRelease(readStream);

if (writeStream)
    CFRelease(writeStream);

【解决方案1】：

试试这个：

CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
CFStreamCreatePairWithSocketToHost(NULL, (__bridge CFStringRef)HOST, PORT, &readStream, &writeStream);

【讨论】：

我需要在 5555 端口上连接到 127.0.0.1，我应该写什么而不是 (__bridge CFStringRef)HOST？
我试试这个CFStringRef str = (CFStringRef)"127.0.0.1"; CFHostRef host = CFHostCreateWithName(kCFAllocatorDefault, str);，但现在主机出现同样的错误。
const NSInteger PORT = 5555; const NSString * HOST = @"127.0.0.1"; CFStreamCreatePairWithSocketToHost(NULL, (__bridge CFStringRef)HOST, PORT, &readStream, &writeStream);
