//本地推送---无需网络,由本地发起
UILocalNotification *localNotification = [[UILocalNotification alloc]init];
//设置推送时间间隔并开启推送fireDate
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:10];
//设置提醒内容
localNotification.alertBody = @"注意要吃饭了";
//设置提醒标题
localNotification.alertTitle = @"提示";
//未读数图标显示badgeNumber
localNotification.applicationIconBadgeNumber = 2;
//定时推送
[[UIApplication shareApplication] scheduleLocalNotification:localNotification];
iOS8 以后需要添加如下步骤
//获取当前设备的系统版本UIDevice
if ([UIDevice currentDevice].systemVersion.floatValue > 8.0) {
UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert categories:nil];
//注册推送 以及 推送相关设置
[[UIApplication sharedApplication]registerUserNotificationSettings:setting];
}
//上文中设置
applicationIconBadgeNumber
在阅读完推送信息后应当清零
此时应该在AppDelegate文件中
设置
//已经收到推送信息后调用的方法
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{
application.applicationIconBadgeNumber = 0;
}
