iOS 消息推送(UserNotifications)
iOS 消息推送
之前没怎么关注 这块 今天要做消息推送 就做个记录 也算是知识的总结啦
理一理头绪 我们要做这件事 要哪些东西
1.请求证书
2.Xcode 打开 接受通知机制 (下面会配图的)
3.NWPusher (测试用的)
其他的兴趣 你们自己了解 我只介绍如何实现消息推送
一 开始下载配置证书
https://developer.apple.com/account/ios/certificate/ (直接进入 证书界面)
上面写的明白 检查一下自己要开发的App ID 在不在里面
如果没有 自己添加一个
这里也是填写你要用到的id
必须勾选上
创建完成之后 回到刚才的页面 点击刚才创建的 ID
没有配置证书都是 黄色的 点击edit 进入
勾选上
我们开始请求证书 首先要打开钥匙串🔑
钥匙串访问 -> 证书助理 -> 从证书颁发机构请求证书..
邮箱我瞎写的 忽略
知道放到哪里去了 直接保存就好了
好了 我们继续生成开发环境下的证书
一直点击下一步 你会看到
选择你刚才创建的文件
生成后 直接下载 双击安装就好了 可以在钥匙串里面找到
相同的方法 请求发布版的证书 这里我就不多重复了
在Keychain Access.app里选定这个新证书(Apple Development Push Services*),导出到桌面,保存为Certificates.p12.
终端上执行 打包证书
openssl pkcs12 -clcerts -nokeys -out cert.pem -in Certificates.p12
openssl pkcs12 -nocerts -out key.pem -in Certificates.p12
openssl rsa -in key.pem -out key.unencrypted.pem
cat cert.pem key.unencrypted.pem > ck.pem
下载 NWPusher
使用界面就是这样的 很简单,但是对应的正式不要搞错了 下面的token 是苹果返回的
看代码
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(nonnull NSData *)deviceToken
{
NSLog(@"deviceToken:%@",deviceToken);
NSString *deviceTokenStr = [[[[deviceToken description]
stringByReplacingOccurrencesOfString:@"<" withString:@""]
stringByReplacingOccurrencesOfString:@">" withString:@""]
stringByReplacingOccurrencesOfString:@" " withString:@""];
NSLog(@"deviceTokenStr:%@",deviceTokenStr);
}
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{
NSLog(@"didFailToRegisterForRemoteNotificationsWithError:%@",error);
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{
NSLog(@"willPresentNotification:%@",notification.request.content.title);
// 这里真实需要处理交互的地方
// 获取通知所带的数据
NSString *apsContent = [notification.request.content.userInfo objectForKey:@"aps"];
NSLog(@"%@",apsContent);
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
//在没有启动本App时，收到服务器推送消息，下拉消息会有快捷回复的按钮，点击按钮后调用的方法，根据identifier来判断点击的哪个按钮
NSString *apsContent = [response.notification.request.content.userInfo objectForKey:@"aps"];
NSLog(@"didReceiveNotificationResponse:%@",response.notification.request.content.title);
NSLog(@"%@",apsContent);
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}
//远程推送APP在前台
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{
NSLog(@"didReceiveRemoteNotification:%@",userInfo);
}
- (void)setUpCategory
{
UNNotificationAction *action1 = [UNNotificationAction actionWithIdentifier:@"enterApp" title:@"进入应用" options:UNNotificationActionOptionForeground];
UNNotificationAction *action2 = [UNNotificationAction actionWithIdentifier:@"destructive" title:@"忽略" options:UNNotificationActionOptionDestructive];
//UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"helloIdentifier" actions:@[action1,action2] minimalActions:@[action1,action2] intentIdentifiers:@[] options:UNNotificationCategoryOptionNone];
UNNotificationCategory *caregory = [UNNotificationCategory categoryWithIdentifier:@"helloIdentifier" actions:@[action1,action2] intentIdentifiers:@[action1,action2] options:UNNotificationCategoryOptionNone];
[[UNUserNotificationCenter currentNotificationCenter] setNotificationCategories:[NSSet setWithObjects:caregory, nil]];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// iOS10 下需要使用新的 API
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 10.0) {
#ifdef NSFoundationVersionNumber_iOS_9_x_Max
UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound + UNAuthorizationOptionBadge)
completionHandler:^(BOOL granted, NSError * _Nullable error) {
// Enable or disable features based on authorization.
if (granted) {
[application registerForRemoteNotifications];
}
}];
center.delegate = self;
#endif
}
else if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {
UIUserNotificationType myTypes = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:myTypes categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}
NSDictionary *userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (userInfo) {
NSLog(@"从消息启动:%@",userInfo);
// [BPush handleNotification:userInfo];
}
//角标清0
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
return YES;
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSLog(@"didReceiveRemoteNotification : %@",userInfo);
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{
NSLog(@"notification : %@",notification);
}
- (void)applicationDidBecomeActive:(UIApplication *)application //后台切换到前台的 或者应用激活的时候调用
{
// 清除图标数字
application.applicationIconBadgeNumber = 0;
}
下面开始 Xcode 里面的设置
后台设置
关于消息推送和服务器的交互 还有角标的清除 我会在下篇文章里面介绍 谢谢
