Question

我可以连接到流但我无法显示此信息。如果我使用终端连接，我可以看到xml格式的流，但是在这段代码中我想在NSLog中看到它

这是我的代码，任何帮助都会很棒

#import "_CViewController.h"


@interface _CViewController ()

@end

@implementation _CViewController
@synthesize inStreamDictionary=_inStreamDictionary;

-(NSMutableDictionary *)inStreamDictionary{
    if(!_inStreamDictionary){
        _inStreamDictionary=[[NSMutableDictionary alloc] init];
    }
    return _inStreamDictionary;
}

    - (void)viewDidLoad
{
    [super viewDidLoad];




    NSString *deviceAddress = @"192.168.0.5";
    int devicePort=80;


//open stream

//CFReadStreamSetProperty(readStream,kCFStreamNetworkServiceTypeVoIP,kCFBooleanTrue);
//CFWriteStreamSetProperty(writeStream,kCFStreamNetworkServiceTypeVoIP,kCFBooleanTrue);

inputStream = (__bridge NSInputStream *)readStream;

您似乎没有设置流的代理，因此我不清楚您将如何获取数据。

此外，您似乎可以使用NSURLRequest并以三行代码完成所有这些操作。

试图让NSStream在NSlog中显示
