特定日期的本地通知

Question

我想每周三下午6点重复一次本地通知消息。

我该怎么做？

目前我使用以下代码。但即使我尝试，此时也没有任何事情发生。我记录了UIDate，它显示我0001-01-01 17:25:52。我想通了，这是一个错误的时区。我在CEST时区。我该如何改变呢？

- (void)applicationDidEnterBackground:(UIApplication *)application {

//Calendar
NSCalendar *gregCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
NSDateComponents *dateCompnent = [gregCalendar components:NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitWeekday fromDate:[NSDate date]];

[dateCompnent setWeekday:4];
[dateCompnent setHour:18];
[dateCompnent setMinute:00];

UIDatePicker *dd = [[UIDatePicker alloc] init];
[dd setDate:[gregCalendar dateFromComponents:dateCompnent]];

//Notification
UILocalNotification *notification = [[UILocalNotification alloc] init];
[notification setAlertBody:@"Test Notification"];
[notification setFireDate:dd.date];
[notification setSoundName:@"sound.mp3"];
[notification setTimeZone:[NSTimeZone defaultTimeZone]];
[application setScheduledLocalNotifications:[NSArray arrayWithObject:notification]];
}

您可以在日期组件中添加年，月和日。
