PhoneGap iOS LocalNotifications夏令时 [英] PhoneGap iOS LocalNotifications Daylight Savings

问题描述

我在使用（臭名昭着的） iOS中的Drew Dahlman的Phonegap本地通知 。 < em>工作。

我从来没有写过一行 objective-c （这可能是为什么我现在有麻烦了）但我认为插件不工作正常，并希望尽可能解决它。

当我设置一个通知今天在13:00它火灾正确。但是，当夏令时播放时，通知会在14:00（一小时后）发出。

这是因为时区不在考虑范围内吗？ Drew提到时区设置为+0000不是一个问题，但这是错误的信息？我应该更新插件来处理时区和夏令时吗？或者在我自己的代码中处理夏令时，只是在DST活动时设置日期-1小时？

我想我必须更新第二行> LocalNotification.m ，但正如我所说，我不确定要更新的内容。

  UILocalNotification * notif = [[UILocalNotification alloc] init]; 
 notif.timeZone = [NSTimeZone defaultTimeZone]; 
  

解决方案

Ah似乎有一个奇怪的问题

示例1：
当我这样做时， duedate 是2013-04-08T21：30的值

  var d = new Date（duedate）。 getTime（）; 
 d = new Date（d）; 
 
 plugins.localNotification.add（{
 date：d，
 ... 
  

通知记录为设置为21:30，如下所示：

通知设置： 04-08 21:30:00 +0000





示例2： c> duedate 这样：（现在的时间是21:30）

  var d = new Date（）。getTime（）; 
  

通知记录为设置为20:30，像这样：

通知集：2013-04-08 20:30:00 +0000

但在第二个示例中，由于节省了日光，通知在21:30发出。

解决方案（排序）

我要添加或减去现在和我想要的时间之间的时间差通知火，而不是专门设置日期。

I'm using (the infamous) Drew Dahlman's Phonegap Local Notifications in iOS. And it seems to work.

I have never written a line of objective-c and would prefer not to (which is probably why I'm having trouble now!) but I think the plugin is not working quite right and would like to fix it if possible.

When I set a notification for today at 13:00 it fires correctly. However when daylight savings is in play the notification fires at 14:00, an hour late.

Is this because timezones are not being taken into account? Drew mentions that the timezone being set to +0000 is not a problem, but is this mis-information? Should I update the plugin to handle timezones and daylight savings? Or handle daylight saving in my own code and simply set the date -1 hour when DST is active?

I think I have to update the second of these lines in LocalNotification.m but as I said I am unsure of what to update it to.

UILocalNotification *notif = [[UILocalNotification alloc] init];
notif.timeZone = [NSTimeZone defaultTimeZone];

解决方案

Ah there seems to be a bit of a strange issue when notifications are set.

Example 1: When I do something like this, where duedate is a value of 2013-04-08T21:30

var d = new Date(duedate).getTime();
d = new Date(d);

plugins.localNotification.add({
date: d,
...

The notification is logged as being set for 21:30, like so:

Notification Set: 2013-04-08 21:30:00 +0000

Example 2: if I set the duedate like this: (where the time now is 21:30)

var d = new Date().getTime();

The notification is logged as being set for 20:30, like so:

Notification Set: 2013-04-08 20:30:00 +0000

However in the second example the notification fires at 21:30, due to day light savings.

Solution (of sorts)

I'm going to have to add or subtract the difference in time between now and when I want the notification to fire, rather than set the date specifically.
