如何在工作日的选择列表中设置重复UILocal通知 [英] How to set the repeat UILocal Notifications on the select list of Weekdays

问题描述

我已使用以下链接实施 UILocal通知

I have implemented UILocal Notification using the following link

http://useyourloaf.com/blog/2010/07/31/adding-local-notifications-with-ios -4.html

我已修改它以使用

//To set the repeat notification
            notif.repeatInterval = NSDayCalendarUnit;

例如ex 每天上午10点

但我的要求是用户需要在选定的周日（周一至周日）设置通知

But my requirement is user needsto set the notification on selected Week Days (Monday to saturDay)

为什么因为用户可能每周假期（周六和周日）/周五 - 周日）/其他几天 ..

why because user may have weekly holidays like (SaturDay and Sunday) / Friday - Sunday) / Some other days..

周假他不应该发出通知。

所以我们祝贺用户设置选中工作日和通知将仅在那些日期设置..一旦用户设置通知。

So we felicitate user to set the selected Working days and the notifications will set on those days only.. once user set the notifications.

例如：

我们有工作日Sun，MOn，星期二，星期三，星期四，星期五，星期六的清单

这些用户选择星期一，星期二，星期四，星期四。并设置为10Am

然后通知将在当天上午1​​0点开启。

如何操作

推荐答案

UILocalNotification的API在这方面非常有限 - 您必须在用户选择的日期手动安排每周重复的4个事件。

The API for UILocalNotification is very limited in this regard - you'll have to manually schedule 4 events repeating weekly on the days that the user selects.

为星期一安排重复计时器的示例如下所示

An example of scheduling a repeat timer for monday would look like this

NSDateComponents *dateComponents = [[NSDateComponents alloc] init];
dateComponents.weekday = 2; // sunday = 1 ... saturday = 7
dateComponents.hour    = 10;

UILocalNotification *notification = //...
notification.repeatInterval = NSWeekCalendarUnit;
notification.fireDate       = [calendar dateFromComponents:dateComponents];

日期编号可在 NSDateComponents类参考
