我们有时候有需要本地通知的功能
本地推送通知也需要申请推送通知权限，具体步骤可看我的上一篇博客（关于推送权限申请）
1、添加本地推送的方法，需要判断iOS10.0和iOS8.0不同的方法
#import <UserNotifications/UserNotifications.h>
/** 添加本地推送通知*/+ (void)addLocalNotificationWithTitle:(NSString *)title subTitle:(NSString *)subTitle body:(NSString *)body timeInterval:(long)timeInterval identifier:(NSString *)identifier userInfo:(NSDictionary *)userInfo repeats:(int)repeats{ if (title.length == 0 || body.length == 0 || identifier.length == 0) { return; } if (@available(iOS 10.0, *)) { UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init]; // 标题 if (title.length) { content.title = title; } if (subTitle.length) { content.subtitle = subTitle; } // 内容 if (body.length) { content.body = body; } if (userInfo != nil) { content.userInfo = userInfo; } // 声音 // 默认声音 content.sound = [UNNotificationSound defaultSound]; // 添加自定义声音 //content.sound = [UNNotificationSound soundNamed:@"Alert_ActivityGoalAttained_Salient_Haptic.caf"]; // 角标 （我这里测试的角标无效，暂时没找到原因） content.badge = @1; // 多少秒后发送,可以将固定的日期转化为时间 NSTimeInterval time = [[NSDate dateWithTimeIntervalSinceNow:timeInterval] timeIntervalSinceNow]; UNNotificationTrigger *trigger = nil; // repeats，是否重复，如果重复的话时间必须大于60s，要不会报错 if (repeats > 0 && repeats < 7) { NSDate *date = [NSDate dateWithTimeIntervalSinceNow:timeInterval]; // 定义一个时间字段的旗标，指定将会获取指定年、月、日、时、分、秒的信息 unsigned unitFlags = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitWeekday | NSCalendarUnitMinute | NSCalendarUnitSecond; NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian]; // 获取不同时间字段的信息 NSDateComponents* comp = [gregorian components:unitFlags fromDate:date]; NSDateComponents *components = [[NSDateComponents alloc] init]; components.second = comp.second; if (repeats == 6) { //每分钟循环 } else if (repeats == 5) { //每小时循环 components.minute = comp.minute; } else if (repeats == 4) { //每天循环 components.minute = comp.minute; components.hour = comp.hour; } else if (repeats == 3) { //每周循环 components.minute = comp.minute; components.hour = comp.hour; components.weekday = comp.weekday; } else if (repeats == 2) { //每月循环 components.minute = comp.minute; components.hour = comp.hour; components.day = comp.day; components.month = comp.month; } else if (repeats == 1) { //每年循环 components.minute = comp.minute; components.hour = comp.hour; components.day = comp.day; components.month = comp.month; components.year = comp.year; } trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:YES]; } else { //不循环 trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:time repeats:NO]; } // 添加通知的标识符，可以用于移除，更新等操作 identifier UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:identifier content:content trigger:trigger]; [center addNotificationRequest:request withCompletionHandler:^(NSError *_Nullable error) { NSLog(@"ECKPushSDK log:添加本地推送成功"); }]; } else { UILocalNotification *notif = [[UILocalNotification alloc] init]; // 发出推送的日期 notif.fireDate = [NSDate dateWithTimeIntervalSinceNow:timeInterval]; if (title.length > 0) { notif.alertTitle = title; } // 推送的内容 if (body.length > 0) { notif.alertBody = body; } if (userInfo != nil) { NSMutableDictionary *mdict = [NSMutableDictionary dictionaryWithDictionary:userInfo]; [mdict setObject:identifier forKey:@"identifier"]; notif.userInfo = mdict; } else { // 可以添加特定信息 notif.userInfo = @{ @"identifier":identifier}; } // 角标 notif.applicationIconBadgeNumber = 1; // 提示音 notif.soundName = UILocalNotificationDefaultSoundName; // 循环提醒 if (repeats == 6) { //每分钟循环 notif.repeatInterval = NSCalendarUnitMinute; } else if (repeats == 5) { //每小时循环 notif.repeatInterval = NSCalendarUnitHour; } else if (repeats == 4) { //每天循环 notif.repeatInterval = NSCalendarUnitDay; } else if (repeats == 3) { //每周循环 notif.repeatInterval = NSCalendarUnitWeekday; } else if (repeats == 2) { //每月循环 notif.repeatInterval = NSCalendarUnitMonth; } else if (repeats == 1) { //每年循环 notif.repeatInterval = NSCalendarUnitYear; } else { //不循环 } [[UIApplication sharedApplication] scheduleLocalNotification:notif]; }} 2、移除本地推送通知的方法
/** 移除某一个指定的通知*/+ (void)removeNotificationWithIdentifierID:(NSString *)noticeId{ if (@available(iOS 10.0, *)) { UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; [center getPendingNotificationRequestsWithCompletionHandler:^(NSArray * _Nonnull requests) { for (UNNotificationRequest *req in requests){ NSLog(@"ECKPushSDK log: 当前存在的本地通知identifier: %@\n", req.identifier); } }]; [center removePendingNotificationRequestsWithIdentifiers:@[noticeId]]; } else { NSArray *array = [[UIApplication sharedApplication] scheduledLocalNotifications]; for (UILocalNotification *localNotification in array){ NSDictionary *userInfo = localNotification.userInfo; NSString *obj = [userInfo objectForKey:@"identifier"]; if ([obj isEqualToString:noticeId]) { [[UIApplication sharedApplication] cancelLocalNotification:localNotification]; } } }}/** 移除所有通知*/+ (void)removeAllNotification{ if (@available(iOS 10.0, *)) { UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; [center removeAllPendingNotificationRequests]; }else { [[UIApplication sharedApplication] cancelAllLocalNotifications]; }} 3、接收到通知处理
iOS10.0之前的接收方法，在Appdelegate中重写下面方法
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{ //接收到本地通知方法}- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{ //接收到远程通知方法} iOS10.0以后的接收推送方法
#import//首先需要设置代理UNUserNotificationCenterDelegateif ([[UIDevice currentDevice].systemVersion floatValue] >= 10.0){ UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; center.delegate = self; [center removeAllPendingNotificationRequests]; }//再实现UNUserNotificationCenterDelegate代理的方法- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{ //应用在前台时候接收到本地推送通知、远程推送通知调用此方法}- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)(void))completionHandler{ //应用程序在后台，用户通过点击本地推送、远程推送进入app时调用此方法}
