我当地的通知太早了大约2个小时。我在剧集中设置它的日期 2013-12-13 17:00:00 +0000
然而,我的手机在15:00:00向我开了通知。我想让它在用户当地时间点火。如何调整日期以便在用户的当地时区点火...即。无论你在美国的哪个地方,都会在17:00:00开火?
这是我的NSDate之旅。我解析一个XML文件。来自pubDate标签:
NSDate *articleDate = [NSDate dateFromInternetDateTimeString:articleDateString formatHint:DateFormatHintRFC822];
NSString *articleImage = [item valueForChild:@"description"];
NSDateFormatter * dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setTimeStyle:NSDateFormatterShortStyle];
[dateFormatter setDateStyle:NSDateFormatterShortStyle];
NSString *dateofarticle = [dateFormatter stringFromDate:articleDate];
NSDate *date = [dateFormatter dateFromString:dateofarticle];
NSDate * date从我设置的自定义类添加到属性,以存储来自XML的每个项目的所有内容。因此,用于通知的NSDate就是这样。当我设置通知时,我不对NSDate进行任何调整。
来自提醒UIActivity:
- (void)prepareWithActivityItems:(NSArray *)activityItems
{NSLog(@"works");
Class cls = NSClassFromString(@"UILocalNotification");
if (cls != nil) {
NSString *message = [@"5 minutes until " stringByAppendingString:self.thetitle];
UILocalNotification *notif = [[cls alloc] init];
// NSLog(@"%@", self.thedate);
NSDate *newDate = [self.thedate dateByAddingTimeInterval:-60*5];
NSDateFormatter *formatter3 = [[NSDateFormatter alloc] init];
[formatter3 setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
[formatter3 setTimeStyle:NSDateFormatterShortStyle];
[formatter3 setDateStyle:NSDateFormatterShortStyle];
NSString *detailstext = [formatter3 stringFromDate:newDate];
NSDate *othernewdate = [formatter3 dateFromString:detailstext];
NSLog(@"other%@", othernewdate);
notif.timeZone = [NSTimeZone systemTimeZone];
notif.fireDate = othernewdate;
//NSLog(@"newdate%@", newDate);
notif.alertBody = message;
notif.alertAction = @"Ok";
notif.soundName = UILocalNotificationDefaultSoundName;
notif.applicationIconBadgeNumber = 1;
notif.repeatInterval = 0;
NSDictionary *userDict = [NSDictionary dictionaryWithObject:message
forKey:kRemindMeNotificationDataKey];
notif.userInfo = userDict;
[[UIApplication sharedApplication] scheduleLocalNotification:notif];
[self.notifications addObject:notif];
[notif release];
}
NSLog(@"Test");
[self activityDidFinish:YES];
}
- (void)showReminder:(NSString *)text {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Reminder"
message:text delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alertView show];
[alertView release];
}
NSLog(@“other%@”,othernewdate);在控制台中显示为2013/12/13 16:55:00 +0000。我在中央时区。
更新#2 在安排通知的区域,我正在运行一些测试。之后我将XML pubDate更改为显示-0600,因此它将保持中央时间。我运行此代码并记录日志。
NSDateFormatter *formatter3 = [[NSDateFormatter alloc] init];
[formatter3 setTimeStyle:NSDateFormatterShortStyle];
[formatter3 setDateStyle:NSDateFormatterShortStyle];
NSString *detailstext = [formatter3 stringFromDate:self.thedate];
NSDate *othernewdate = [formatter3 dateFromString:detailstext];
NSLog(@"details%@", detailstext);
NSLog(@"other%@", othernewdate);
字符串显示以下特定条目的正确日期和时间:
details12 / 27/13,3:00 PM
NSDate显示了这一点。所以,我的问题是这个。由于以下时间在技术上是相同的时间......通知应该正确启动吗?:
other2013-12-27 21:00:00 +0000
答案 0 :(得分:3)
确保将有效的时区对象分配给本地通知,即:
localNotification.timeZone = [NSTimeZone systemTimeZone];
如果您需要在 时区17:00触发通知,请使用timeZoneWithName:
创建时区的时区对象,并将其设置为本地通知&# 39; s时区。
