对Bonjour完全小白的同学,推荐一篇文章
iOS开发 Bonjour的使用,在此也感谢此篇的作者,毕竟站在巨人的肩膀上做事情,事半功倍!
假如你看完了上面的文章, 对Bonjour已经有了一个基本的认识,那我们这里就直接进入主题,如果在实战中使用. 想法也是封装出一个工具类,方便使用,当然要达到如下效果
1.最好是单例
2.最好使用简单,方便使用
3.能发现所有的设备及返回所有设备的相关信息(看了很多文章都没有处理这一步,大多只是发现一台设备,没有对多台设备进行处理,也没有返回给外面使用)
回到正题
直接新建一个类,类名叫FindDeviceServiceTool 继承自NSObject,FindDeviceServiceTool.h文件如下:
#import <Foundation/Foundation.h>
typedef void(^ResultBlock)(NSArray * _Nullable resultArray);
NS_ASSUME_NONNULL_BEGIN
@interface FindDeviceServiceTool : NSObject
+(FindDeviceServiceTool *) sharedInstance;
@property (nonatomic,copy) ResultBlock resultBlock;
-(void)createServiceBrowser;
@end
NS_ASSUME_NONNULL_END
FindDeviceServiceTool.m文件如下:
//
// FindDeviceServiceTool.m
// Bonjour_OC_demo
//
// Created by zz on 2021/9/10.
//
#import "FindDeviceServiceTool.h"
#include <arpa/inet.h>
@interface FindDeviceServiceTool ()<NSNetServiceDelegate,NSNetServiceBrowserDelegate>
//定义NSNetService，NSNetServiceBrowser两个变量以及添加代理
@property(strong,nonatomic)NSNetServiceBrowser *brower;
//是为了保存服务,不让其立马销毁,这样后面的代理方法才能起到作用
@property(strong,nonatomic)NSMutableArray *serviceArray;
//结果数组,供外界使用
@property(strong,nonatomic)NSMutableArray *resultArray;
@end
@implementation FindDeviceServiceTool
- (NSMutableArray *)serviceArray{
if (_serviceArray == nil) {
_serviceArray = [[NSMutableArray alloc]init];
}
return _serviceArray;
}

return _resultArray;
}

}
//解析服务失败，解析出错
- (void)netService:(NSNetService *)netService didNotResolve:(NSDictionary *)errorDict {
NSLog(@"解析出错didNotResolve: %@",errorDict);
}
@end
封装工具类完成后,使用的地方,就比较简单了,代码如下:
[FindDeviceServiceTool.sharedInstance createServiceBrowser];
FindDeviceServiceTool.sharedInstance.resultBlock = ^(NSArray * _Nullable resultArray) {
NSLog(@"你想的信息都在这里-------->%@",resultArray);
};
最终的效果如下图

注意点,使用Bonjour需要申请要权限
image.png
红框里面的4个权限最好都申请一下
<key>NSLocalNetworkUsageDescription</key>
<string>Used to scan and find nearby gateway devices, please authorize, otherwise the configuration gateway device function cannot be used normally</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>We need access to your location for creating an account and for sending push notifications</string>
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>We need access to your location for creating an account and for sending push notifications</string>
<key>NSBonjourServices</key>
<array>
<string>_x5_gw._tcp</string>
</array>

补充一下
感谢小伙伴们的关注, 针对有的小伙伴说,没有正常收到消息的问题,在这里补充一下:
Bonjour正确的流程应该是这样的:
第一步: 去局域网中注册Bonjour服务,至于怎么注册及注册过程,此篇文章没有涉及到,请自行研究; 或者让你们公司的硬件工程师去注册Bonjour服务; 注册Bonjour服务这一端,相当于是服务端,只有先有了服务端,有了这个服务,我们iOS工程,作为客户端,才能找到这个服务.
第二步:在iOS工程里面要申请4个权限
第三步:在使用的过程 ,请把我测试的type字符串:"_x5_gw._tcp",改成你们自己的type字符串, 申请权限那边的type字符串,也记得一起改
第四步:才是使用上面封装的工具, 在第一步注册的局域网中去发现服务.
注册Bonjour服务 与 发现服务 一定是在同一局域网中进行; 注册Bonjour服务 与 发现服务 一定是在同一局域网中进行; 注册Bonjour服务 与 发现服务 一定是在同一局域网中进行. 通常情况下,就是在同一个路由器wifi下进行Bonjour注册, 与 Bonjour的服务发现!!!! 最后祝君好运~
