iOS中的用戶時區的本地通知設置默認時間爲上午9:00

Question

我想爲每個用戶時區時間設置通知默認9:00。

如何創建啓用日期默認時間爲上午9:00。

Answer 1

你好，我懂了這個答案： -

NSDate *pickerDate = [NSDate date]; 
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc]init]; 
    [dateFormatter setDateFormat:DT_FORMATE_BIRTHDATE]; 
    NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:DT_TIME_ZONE_GMT]; 
    [dateFormatter setTimeZone:gmt]; 

    NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar]; 
    NSDateComponents *timeComponents = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit) 
                fromDate:pickerDate]; 
    [timeComponents setHour:9]; 
    [timeComponents setMinute:00]; 
    [timeComponents setSecond:0]; 

    NSDate *dtFinal = [calendar dateFromComponents:timeComponents]; 
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; 
    [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss Z"]; 

    NSString *fierDate = [formatter stringFromDate:dtFinal];

[NSTimeZone defaultTimeZone] 

[NSTimeZone systemTimeZone] 

[NSTimeZone localTimeZone] 

NSTimeZone: what is the difference between localTimeZone and systemTimeZone?

Answer 3

試試這個代碼。

NSDate *pickerDate = [date_picker date]; 
// Schedule the notification 
UILocalNotification* localNotification = [[UILocalNotification alloc] init]; 
localNotification.fireDate = pickerDate; 
localNotification.alertBody = @"Alert Body Message"; 
localNotification.alertAction = @"Alert Action Message"; 
localNotification.timeZone = [NSTimeZone defaultTimeZone]; 
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
