获取iOS推送deviceToken的详细源码

发布时间：2021-09-26作者：Topwo来源：原创点击：385

### [获得deviceToken的过程]
#### 1>客户端向苹果服务APNS,发送设备的UDID和英语的Bundle Identifier.
#### 2>经苹果服务器加密生成一个deviceToken
#### 3>将当前用户的deviceToken(用户标识),发送给自己应用的服务器
#### 4>自己的服务器,将得到的deviceToken,进行保存
#### 5>需要推送的时候,将消息和deviceToken一起发送给APNS,苹果服务器,再通过deviceToken找到用户,并将消息发给用户
```objective-c
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

if ([[UIDevice currentDevice].systemVersion doubleValue] >= 8.0) {
        // 1.注册UserNotification,以获取推送通知的权限
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge categories:nil];
        [application registerUserNotificationSettings:settings];

// 2.注册远程推送
        [application registerForRemoteNotifications];
    } else {
        [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeNewsstandContentAvailability | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound];
    }

return YES;
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    // <32e7cf5f 8af9a8d4 2a3aaa76 7f3e9f8e 1f7ea8ff 39f50a2a e383528d 7ee9a4ea>
    // <32e7cf5f 8af9a8d4 2a3aaa76 7f3e9f8e 1f7ea8ff 39f50a2a e383528d 7ee9a4ea>
    NSLog(@"%@", deviceToken.description);

//Xcode11打的包，iOS13获取Token有变化
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 13) {
        if (![deviceToken isKindOfClass:[NSData class]]) {
            //记录获取token失败的描述
            return;
        }
        const unsigned *tokenBytes = (const unsigned *)[deviceToken bytes];
        NSString *strToken = [NSString stringWithFormat:@"%08x%08x%08x%08x%08x%08x%08x%08x",
                              ntohl(tokenBytes[0]), ntohl(tokenBytes[1]), ntohl(tokenBytes[2]),
                              ntohl(tokenBytes[3]), ntohl(tokenBytes[4]), ntohl(tokenBytes[5]),
                              ntohl(tokenBytes[6]), ntohl(tokenBytes[7])];
        NSLog(@"deviceToken1:%@", strToken);
        return;
    } else {
        NSString *token = [NSString
                       stringWithFormat:@"%@",deviceToken];
        token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""];
        token = [token stringByReplacingOccurrencesOfString:@">" withString:@""];
        token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
        NSLog(@"deviceToken2 is: %@", token);
    }
}
```
### [证书的配置步骤]
#### 1>创建明确的AppID,只有明确的AppID才能进行一些特殊的操作
#### 2>真机调试的APNS SSL证书
#### 3>发布程序的APNS SSL证书
#### 4>生成描述文件
### [依次安装证书,再装描述]
