NSNetServiceBrowser in iOS6不起作用

Question

我在做台式机客户端在本地网络上打电话的广告。我的手机是6.0.2，Xcode 4.5.2。

我知道桌面应用程序正在成功注册，因为我手机上的发现应用程序(Tildesoft)显示了我在网络上的服务(这也排除了wifi问题)。

我已经下载了苹果应用程序示例Bonjour Web。查找"_myservice._tcp“的委托从来没有触发过，但是开始浏览方法确实会触发。

我尝试使用HHServices (包装DNSService)，当开始浏览方法启动时，服务查找方法没有启动。

在我自己的应用程序中，我尝试使用NSNetServiceBrowser。我设置了委托，我的"netServiceBrowserWillSearch“委托方法就会被触发，但其他任何事情都不会发生。

如果要验证，则附加代码。

标题：

#import <UIKit/UIKit.h>
@interface ClientFinder_ViewController : UIViewController<UITableViewDataSource, UITableViewDelegate,NSNetServiceBrowserDelegate>

@property (weak, nonatomic) IBOutlet UITableView *availableClientsTableView;


-(void)netServiceBrowser:(NSNetServiceBrowser *)aNetServiceBrowser didFindDomain:(NSString *)domainString moreComing:(BOOL)moreComing;
-(void)netServiceBrowser:(NSNetServiceBrowser *)aNetServiceBrowser didFindService:(NSNetService *)aNetService moreComing:(BOOL)moreComing;
-(void)netServiceBrowser:(NSNetServiceBrowser *)aNetServiceBrowser didNotSearch:(NSDictionary *)errorDict;
-(void)netServiceBrowserDidStopSearch:(NSNetServiceBrowser *)aNetServiceBrowser;
-(void)netServiceBrowserWillSearch:(NSNetServiceBrowser *)aNetServiceBrowser;

@end

相关执行情况：

- (void)viewDidLoad
{
    [super viewDidLoad];
    dictionaryFoundClients = [[NSMutableDictionary alloc] initWithCapacity:1];
    [self addLogoToNabar];
    [self listen];
}

-(void)listen{
    NSNetServiceBrowser *serviceBrowser = [NSNetServiceBrowser new];
    [serviceBrowser setDelegate:self];
    [self.netServiceBrowser searchForServicesOfType:TYPE inDomain:domain];
}


-(void)netServiceBrowser:(NSNetServiceBrowser *)aNetServiceBrowser didFindDomain:(NSString *)domainString moreComing:(BOOL)moreComing{
    NSLog(@"aNetServiceBrowser didFindDomain");
}


-(void)netServiceBrowser:(NSNetServiceBrowser *)aNetServiceBrowser didFindService:(NSNetService *)aNetService moreComing:(BOOL)moreComing{
    NSLog(@"aNetServiceBrowser didFindService");
    [dictionaryFoundClients setObject:aNetService forKey:aNetService.hostName];
    NSLog(@"Found service: %@ @ %@", aNetService.name, aNetService.hostName);
}

-(void)netServiceBrowser:(NSNetServiceBrowser *)aNetServiceBrowser didNotSearch:(NSDictionary *)errorDict{
    NSLog(@"aNetServiceBrowser didNotSearch. Errors enumerated");
    for(int a=0; a< errorDict.count; a++){
        NSString *key = [[errorDict allKeys] objectAtIndex:a];
        NSString *val = [errorDict objectForKey:key];
        NSLog(@"%@: %@", key, val);
    }
}

-(void)netServiceBrowserDidStopSearch:(NSNetServiceBrowser *)aNetServiceBrowser{
    NSLog(@"netServiceBrowserDidStopSearch");
}

-(void)netServiceBrowserWillSearch:(NSNetServiceBrowser *)aNetServiceBrowser{
    NSLog(@"netServiceBrowserWillSearch");
}

Answer 1

不知道它为什么开始工作，但下面是我的工作代码：

    [self stopCurrentResolve];
    [self.netServiceBrowser stop];
    [self.services removeAllObjects];

    NSNetServiceBrowser *aNetServiceBrowser = [[NSNetServiceBrowser alloc] init];
    if(!aNetServiceBrowser) {
        // The NSNetServiceBrowser couldn't be allocated and initialized.
        return NO;
    }

    aNetServiceBrowser.delegate = self;
    self.netServiceBrowser = aNetServiceBrowser;
    [self.netServiceBrowser searchForServicesOfType:type inDomain:domain];

Answer 2

如果所有这些都是本地的，则需要使用searchForServicesOfType:方法而不是searchForRegistrationDomains方法。

-(void)listen{
  NSNetServiceBrowser *serviceBrowser = [NSNetServiceBrowser new];
  [serviceBrowser setDelegate:self];
  [serviceBrowser searchForServicesOfType:@"_your_service_type._tcp" inDomain:@""];;
}

"_your_service_type._tcp“是桌面应用程序在宣传其服务时使用的服务类型。
