本地通知簡介:

本地通知簡單來說app本身給應(yīng)用程序推送消息，不需要服務(wù)器支持。使用場景：鬧鐘，定時操作。

1.創(chuàng)建本地通知

//? 創(chuàng)建本地通知對象

UILocalNotification *localNoti = [[UILocalNotification alloc] init];

2.設(shè)置本地通知屬性

NSDateFormatter *date_formatter = [[NSDateFormatter alloc] init];

[date_formatter setDateFormat:@"yyyy-MM-dd"];

NSString *TimeStr = [date_formatter stringFromDate:[NSDate date]];

/** 目前是定時每天九點(diǎn)，后續(xù)版本迭代在封裝 */

TimeStr = [NSString stringWithFormat:@"%@ 09:00:00",TimeStr];

[date_formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];

NSDate *dateTime = [date_formatter dateFromString:TimeStr];

//1.設(shè)置推送類型

---

UIUserNotificationType type = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;

//2.設(shè)置setting

UIUserNotificationSettings *setting? = [UIUserNotificationSettings settingsForTypes:type categories:nil];

//3.主動授權(quán)

[[UIApplication sharedApplication] registerUserNotificationSettings:setting];

//時區(qū)

localNoti.timeZone = [NSTimeZone defaultTimeZone];

//時間

localNoti.fireDate = dateTime;

//重復(fù)間隔

localNoti.repeatInterval = kCFCalendarUnitDay;

//通知內(nèi)容

localNoti.alertBody = @"今日活動任務(wù)有到期";

//通知聲音

localNoti.soundName = UILocalNotificationDefaultSoundName;

//? ? //通知參數(shù)

//? ? localNoti.userInfo = [NSDictionary dictionaryWithObject:@"NotificationStr" forKey:@"Notification"];

//發(fā)送通知:

[[UIApplication sharedApplication] scheduleLocalNotification:localNoti];

3.取消通知

#pragma mark -- 取消通知

- (void)cancelLocalNotification

{

// 獲取所有本地通知數(shù)組

NSArray *localNotifications = [UIApplication sharedApplication].scheduledLocalNotifications;

for (UILocalNotification *notification in localNotifications) {

NSDictionary *userInfo = notification.userInfo;

if (userInfo) {

// 根據(jù)設(shè)置通知參數(shù)時指定的key來獲取通知參數(shù)

NSString *info = userInfo[@"Notification"];

// 如果找到需要取消的通知，則取消

if (info != nil) {

[[UIApplication sharedApplication] cancelLocalNotification:notification];

//圖標(biāo)的數(shù)字清零

([UIApplication sharedApplication].applicationIconBadgeNumber >= 1) ?([UIApplication sharedApplication].applicationIconBadgeNumber -= 1):0 ;

break;

}

}

}
