1.delegate 注册本地通知

#import <UserNotifications/UserNotifications.h>


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    

    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    //请求获取通知权限（角标，声音，弹框）
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if (granted) {
            //获取用户是否同意开启通知
            NSLog(@"request authorization successed!");
        }
    }];
    

    return YES;
}

2.创建通知

#import <UserNotifications/UserNotifications.h>

 //第二步：新建通知内容对象
        UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
        content.title = @"iOS10通知";
        content.subtitle = @"新通知学习笔记";
        content.body = @"新通知变化很大，之前本地通知和远程推送是两个类，现在合成一个了。这是一条测试通知，";
        content.badge = @1;
        UNNotificationSound *sound = [UNNotificationSound soundNamed:@"in.caf"];
        content.sound = sound;
        
        //第三步：通知触发机制。（重复提醒，时间间隔要大于60s）
        UNTimeIntervalNotificationTrigger *trigger1 = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:5 repeats:NO];
        
        //第四步：创建UNNotificationRequest通知请求对象
        NSString *requertIdentifier = @"RequestIdentifier";
        UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:requertIdentifier content:content trigger:trigger1];
        
        //第五步：将通知加到通知中心
        [[UNUserNotificationCenter currentNotificationCenter] addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
            NSLog(@"Error:%@",error);
            
        }];
