苹果远程推送实现笔记（iOS）

本文介绍: iOS远程推送 UNNo ti fi cat ionAc ti on

前提有开发证书 ios–dev.ce r(iOS De v el op m ent) 发布用到证书 ios–dist.c e r(iOS Distribu ti on)

在Identifie rs 页面点+，添加 bundle ID ，例如“com.xxx.yy y”,在配置页面下拉到Push No ti fi cation s，勾上，然后右边看到 edit 链接，点edit会弹窗，提示添加证书（用key chain 生成一份push. ce rtSignin gRequest）,相应导入ce rtSignin gRequest 文件，这样就可以得到两个证书aps_development.cer（开发用到）和a ps.cer（发布用到）

在Pro files 页面点+，生成两份配置 push–dev（开发）和push–appstore（发布）其中的identify就选上面那个“com.xxx.yy y”对应的项

在Keys页面点+，随便填个名字，勾选“Apple Push No tifi cations service (APNs)”,点contin ue，然后下载保存好，文件名暂定叫push.p8 里面也有一个 key ID 假设是“SP12345678”

2. Xcode 代码

在AppDelegate.m中加入

#import <UserNotifications/UserNotifications.h>

在- (BOOL)application:(UIAppli cation *)application didFini shLaunch ingWithOptions:(NSDictiona ry *)launchOptions方法里面注册通知

[UIApplication sharedApplication].applicationIconBadgeNumber=0;
  /*
   identifier：行为标识符，用于调用代理方法时识别是哪种行为。
   title：行为名称。
   uiusernotificationactivationmode：即行为是否打开app。
   authenticationrequired：是否需要解锁。
   destructive：这个决定按钮显示颜色，yes的话按钮会是红色。
   behavior：点击按钮文字输入，是否弹出键盘
   */
  
  UNNotificationAction *action1 = [UNNotificationAction actionWithIdentifier:@"action1" title:@"foreground action" options:UNNotificationActionOptionForeground];
  UNNotificationAction *action2 = [UNNotificationAction actionWithIdentifier:@"action2" title:@"authentication required" options:UNNotificationActionOptionAuthenticationRequired];
  
  UNNotificationCategory *category1 = [UNNotificationCategory categoryWithIdentifier:@"category1" actions:@[action2,action1] intentIdentifiers:@[@"action1",@"action2"] options:UNNotificationCategoryOptionCustomDismissAction];
    
  [[UNUserNotificationCenter currentNotificationCenter] setNotificationCategories:[NSSet setWithObjects:category1, nil]];
  [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:UNAuthorizationOptionBadge|UNAuthorizationOptionSound|UNAuthorizationOptionAlert completionHandler:^(BOOL granted, NSError * _Nullable error) {
    NSLog(@"completionhandler");
  }];
  
    
  [[UIApplication sharedApplication] registerForRemoteNotifications];
  
  [UNUserNotificationCenter currentNotificationCenter].delegate = self;

再添加两个相应函数：

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *) error {
    NSLog(@"Registfail%@",error);
}
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
    NSLog(@"%@",deviceToken);//这里的Token就是我们设备要告诉服务端的Token码，
		unsigned char buffer[1024]={0};
		NSMutableString *mstr = [NSMutableString string];
  for (int i=0; i<deviceToken.length; i++) {
    unsigned char chr = buffer[i];
    [mstr appendFormat:@"%02x",chr];
  }
  NSLog(@"mstr=%@",mstr);  //这个字符串才是需要保存到服务器上面的
	//TODO:发送deviceToken到公司（个人）PHP服务器
}

3. PHP服务器实现：

https://api.sandbox.push.apple.co m/3/device/{device-token} ||dev 开发

https://api.push.apple.co m/3/device/{device-token} || pub 发布

添加 header:

content-type: application/json
apns-topic: com.wancaiinfo.yunzhan365app
apns-priority: 10
apns-push-type: alert
authorization: bearer $jwt

//badge = 6; //显示在icon 里面的数值

body:

{“aps":{"alert":{"title":"title test","body":"content test"},"badge":6,"sound":"default"}}

其中$jwt = $header.$claims.$signCode

$header=Base64(‘{ “alg”: “ES256”, “kid“: “SP12345678(上面提到的key ID)” }’) 结果要替换+为-，/为_; 暂时定义这个函数名JWTBASE64。

$clai ms = JWTBASE64(‘{ “iss“: “(teamId 开发组ID，自己 developer.apple.com上找)”, “iat”: (时间戳)}’);

$signCode= JWTBASE64(sign($header.$clai ms)); 签名后的数据还是要JWTBASE64一把。

sign签名函数可以使用JWT库做到，目前使用加密方法是ES256

4.手动测试（将下面的代码改好，保存为push_test,运行 “chomd +x push_test”加运行权限）

#!/bin/bash

# Get curl with HTTP/2 and openssl with ECDSA: 'brew install curl-openssl'
curl=/usr/bin/curl
openssl=/opt/local/bin/openssl

# --------------------------------------------------------------------------
deviceToken={这里填写在-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken拿到的deviceToken字符串}

authKey="./push.p8"   #（p8文件）
authKeyId=SP12345678 #（key ID）
teamId=Sxxxxxxxxx  # (开发组ID)
bundleId=com.xxx.yyyy  #（Bundle ID）
#endpoint=https://api.development.push.apple.com
endpoint=https://api.sandbox.push.apple.com

read -r -d '' payload <<-'EOF'
{
   "aps": {
      "alert": {
         "title": " test for title",
         "body": "testing ...."
      }
   }
}
EOF

# --------------------------------------------------------------------------

base64() {
   $openssl base64 -e -A | tr -- '+/' '-_' | tr -d =
}

sign() {
   printf "$1"| $openssl dgst -binary -sha256 -sign "$authKey" | base64
}

time=$(date +%s)
header=$(printf '{ "alg": "ES256", "kid": "%s" }' "$authKeyId" | base64)
claims=$(printf '{ "iss": "%s", "iat": %d }' "$teamId" "$time" | base64)
jwt="$header.$claims.$(sign $header.$claims)"

$curl --verbose 
   --header "content-type: application/json" 
   --header "authorization: bearer $jwt" 
   --header "apns-topic: $bundleId" 
   --header "apns-push-type: alert" 
   --data "$payload" 
   $endpoint/3/device/$deviceToken

//—————-后续—————–

在真机测试是遇到

You've implemented -[<UIApplicationDelegate> application:didReceiveRemoteNotification:fetchCompletionHandler:], but you still need to add "remote-notification" to the list of your supported UIBackgroundModes in your Info.plist.
