卓悦通过蓝牙WITHOUT的GameKit？ [英] Bonjour over bluetooth WITHOUT Gamekit ?

问题描述

我想知道用直接通过蓝牙卓悦在iPhone OS 3.0或更高版本，而无需使用的GameKit的可能性。任何人都可以提供任何例子吗？

I am wondering the possibility of directly using bonjour over bluetooth in iPhone OS 3.0 or later without using GameKit. Can anyone provide any examples ?

推荐答案

刚刚公布的服务，就像 TC。说下面：

Just announce the service, just like tc. has said below:

self.netService = [[[NSNetService alloc] initWithDomain:@"" 
                                                   type:@"_http._tcp" 
                                                   name:@"" 
                                                   port:8080] autorelease];
[self.netService publish];

使用iOS5的，但是，let's叩它的蓝牙卓悦默认情况下禁用，所以你必须使用＆LT声明的C API; dns_sd.h＆GT; 。

With iOS5, however, let's-call-it "Bluetooth Bonjour" is disabled by default, so you have to use the C API declared in <dns_sd.h>.

DNSServiceRef serviceRef;
DNSServiceRegister(&serviceRef, // sdRef
                   kDNSServiceFlagsIncludeP2P, // interfaceIndex
                   0, // flags
                   NULL, // name
                   "_http._tcp", // regtype
                   NULL, // domain
                   NULL, // host
                   1291, // port
                   0, // txtLen
                   NULL, // txtRecord
                   NULL, // callBack,
                   NULL // context
                   );

这是刚刚公布的部分;解决更复杂一点。我建议你​​看看苹果下面的例子：

This is just the announcement part; resolving is a bit more complex. I suggest you take a look at the following examples from Apple:

• SRVResolver - 演示了如何查找使用＆LT宣布API的服务; dns_sd.h＆GT; 。目标OS X，但包括一个叫做 SRVResolver 类，你可以在iOS上使用一样容易，你可以在OS X上使用它的iOS 5蓝牙P2P工作，更新来电 DNSServiceQueryRecord（）通过 kDNSServiceFlagsIncludeP2P 为 interfaceIndex 。 （注意！此示例似乎并不在OS X 10.8 docset的存在，可在10.6和10.7 docsets找到。在10.8，还有的DNSSDObjects例子，但我没有看正是在它做什么。）


• WiTap - 只要你不真正关心在iOS 5支持蓝牙，只看所谓WiTap的例子，它不但彰显美丽的Objective-C API，却怎么也可以创建一个使用CFSocket服务器的API（约BSD套接字薄包装）。你会想在这个看起来即使您正在使用SRVResolver来看看如何使用基于C-API从＆LT; dns_sd.h方式＆gt;

• SRVResolver - demonstrates how you can look up a service using API declared in <dns_sd.h>. Targets OS X, but includes a class called SRVResolver which you can use on iOS as easily as you can use it on OS X. For iOS 5 Bluetooth P2P to work, update the call to DNSServiceQueryRecord() to pass kDNSServiceFlagsIncludeP2P as the interfaceIndex. (NOTE! This sample does not seem to exist in OS X 10.8 docset. It can be found in 10.6 and 10.7 docsets. In 10.8, there's the DNSSDObjects example, but I didn't look exactly at what it does.)
• WiTap - as long as you don't actually care about Bluetooth support on iOS 5, just look at the example called WiTap, which demonstrates not only the beautiful Objective-C API, but also how you can create a server using CFSocket APIs (thin wrappers around BSD sockets). You'll want to look at this even if you are using SRVResolver to see how to use C-based API from <dns_sd.h>.

宣布或解决您的服务后，可以使用常规的BSD套接字听或连接。当编写一个服务器，你甚至会想先听（）端口0（零），然后它随机可用端口分配给您查询。查询该后，宣布这一端口，而不是固定的。这正是WiTap例子做（但CFSocket API，而不是BSD套接字API）。

After announcing or resolving your service, you use regular BSD sockets to listen or connect. When writing a server, you may even want to first listen() on port 0 (zero), and then query which random available port was assigned to you. After querying for that, announce this port instead of a fixed one. That's exactly what WiTap example is doing (but with CFSocket API instead of BSD socket API).

有关BSD套接字的详细信息，只是谷歌周围的教程。

For more info on BSD sockets, just Google around for a tutorial.
