本地推送
1、申请权限，开启通知
2、app 主动向设备的通知中心发送本地消息
3、在设定的触发时间，产生消息推送

- 1 注册，iOS8以上，注册方法不一样，因为新增了 categorys
// app 启动时
if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {
//3.创建UIUserNotificationSettings，并设置消息的显示类类型
UIUserNotificationSettings *notiSettings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIRemoteNotificationTypeSound) categories:nil];
[application registerUserNotificationSettings:notiSettings];
}else{
[application registerForRemoteNotificationTypes: UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound];
}
// 1.如果是正常启动应用程序,那么launchOptions参数是null; 2.如果是通过其它方式启动应用程序,那么launchOptions就值;
if (launchOptions[UIApplicationLaunchOptionsLocalNotificationKey]) {
// 当被杀死状态收到本地通知时执行的跳转代码
NSLog(@"有消息，但是app是，重新启动时");
}
- 2 收到推送消息，处理
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
// 如果是应用程序在前台,依然会收到通知,但是收到通知之后不应该跳转
if (application.applicationState == UIApplicationStateActive) {
NSLog(@"应用在前台");
};
if (application.applicationState == UIApplicationStateInactive) {
// 当应用在后台收到本地通知时执行的跳转代码
NSLog(@"应用后台点击消息时进入app");
}
// UIApplicationStateBackground 这个 多次测试，还不知道什么用，请告知。
}
- 3 脚标处理
- (void)applicationDidBecomeActive:(UIApplication *)application {
// app 重新激活，脚标清零
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}
- 4 实现发送本地消息
UILocalNotification *localNote = [[UILocalNotification alloc] init];
localNote.fireDate = [NSDate dateWithTimeIntervalSinceNow:3.];
localNote.alertBody = @"吃饭了吗?";
localNote.alertAction = @"查看具体的消息";
localNote.hasAction = YES;
localNote.alertLaunchImage = @"icon";
localNote.alertTitle = @"标题";
localNote.soundName = UILocalNotificationDefaultSoundName;
localNote.applicationIconBadgeNumber = 1;
localNote.userInfo = @{@"name" : @"张三", @"toName" : @"李四"};
localNote.repeatInterval = NSDayCalendarUnit;
localNote.category = @"alert";
// 3.调度通知
[[UIApplication sharedApplication] scheduleLocalNotification:localNote];
- 5 iOS8 - categorys
//1.创建消息上面要添加的动作(按钮的形式显示出来)
UIMutableUserNotificationAction *action = [[UIMutableUserNotificationAction alloc] init];
action.identifier = @"action";//按钮的标示
action.title=@"进入app";//按钮的标题
action.activationMode = UIUserNotificationActivationModeForeground;//当点击的时候启动程序
// action.authenticationRequired = YES;
// action.destructive = YES;
UIMutableUserNotificationAction *action2 = [[UIMutableUserNotificationAction alloc] init];
action2.identifier = @"action2";
action2.title=@"知道了";
action2.activationMode = UIUserNotificationActivationModeBackground;//当点击的时候不启动程序，在后台处理
action.authenticationRequired = YES;//需要解锁才能处理，如果action.activationMode = UIUserNotificationActivationModeForeground;则这个属性被忽略；
action.destructive = YES;
//2.创建动作(按钮)的类别集合
UIMutableUserNotificationCategory *categorys = [[UIMutableUserNotificationCategory alloc] init];
categorys.identifier = @"alert";//这组动作的唯一标示,推送通知的时候也是根据这个来区分,在使用推送时选择indentifier
[categorys setActions:@[action,action2] forContext:(UIUserNotificationActionContextDefault)];
然后在注册时候，添加 categories
UIUserNotificationSettings *notiSettings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIRemoteNotificationTypeSound) categories:[NSSet setWithObjects:categorys, nil]];
- 6 iOS8 - categories 点击回调
// 本地通知 iOS 8 外部点击回调
- (void)application:(UIApplication *)application handleActionWithIdentifier:(nullable NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void(^)())completionHandler {
if ([identifier isEqualToString:@"action2"]) {
NSLog(@"action2");
} else {
NSLog(@"action");
}
if (completionHandler) {
completionHandler();
}
}
远程推送
简单流程
1 app设备申请消息推送权限，上报苹果远程通知中心注册
2 苹果远程通知中心注册，返回唯一标识码 deviceToken
3 将返回的唯一标识码deviceToken，上报服务端，保存绑定用户
4 服务器指定推送时，使用deviceToken 上报
5 app设备 在联网状态下，保持与苹果远程通知中心注册长连接。根据deviceToken发送推送消息到指定的app设备
6 远程推送，看极光吧。集成方便。
具体的delegate 与本地的类似，categorys设置一样。
