NSURLErrorDomain代码= -1005“网络连接丢失

Question

当我致电服务时，它将给出以下错误响应。

我做了谷歌，并重新启动了Xcode和模拟器。 它对我不起作用。 即使在设备上，我也面临着同样的问题。 谁能帮我。

服务电话：

    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@?%@", urlString,paramsString]];
    theRequest = [[NSMutableURLRequest alloc] initWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:120.0];

    if (paramsString!=nil)
    {
        NSString *msgLength = [[NSString alloc]initWithFormat:@"%lu",(unsigned long)[paramsString length]];
        [theRequest addValue:msgLength forHTTPHeaderField:@"Content-Length"];
    }
    [theRequest setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [theRequest setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

    [theRequest setValue:[NSString stringWithFormat:@"authToken=%@",self.authToken] forHTTPHeaderField:@"Cookie"];

    theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

    if (theConnection)
    {
        self.receivedData=[[NSMutableData alloc] init];
    }

错误：

Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost." UserInfo=0x7c3770a0 {NSErrorFailingURLStringKey=serviceUrl, _kCFStreamErrorCodeKey=-4, NSErrorFailingURLKey=serviceUrl, NSLocalizedDescription=The network connection was lost., _kCFStreamErrorDomainKey=4, NSUnderlyingError=0x79769170 "The network connection was lost."}

您的Web服务是否符合App Transport安全指南？

如果不是，则应禁用它，或者至少将其配置为与您的应用一起使用。
