Question

我使用以下代码从日期

获取NSString

NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = kCFDateFormatterLongStyle;
df.timeStyle = kCFDateFormatterNoStyle;
df.doesRelativeDateFormatting = YES;
[df setLocale:[NSLocale currentLocale]];
[df  setTimeZone:[NSTimeZone systemTimeZone]];
NSString *dateString=[df stringFromDate:myDate];

但它显示的类似于＆＃39;今天＆＃39;昨天＆＃39;甚至在更改Locale之后。我想显示其本地化语言吗？

我使用了你的代码并创建了这个：

NSDate *yesterday;
NSTimeInterval interval;

NSCalendar *cal = [NSCalendar currentCalendar];

[cal rangeOfUnit:NSDayCalendarUnit
       startDate:&yesterday
        interval:&interval
         forDate:[NSDate date]];

yesterday = [yesterday dateByAddingTimeInterval:-interval];



NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = kCFDateFormatterLongStyle;
df.timeStyle = kCFDateFormatterNoStyle;
df.doesRelativeDateFormatting = YES;

[@[[NSLocale localeWithLocaleIdentifier:@"de_DE"], [NSLocale localeWithLocaleIdentifier:@"es_ES"],[NSLocale localeWithLocaleIdentifier:@"en_US"]] enumerateObjectsUsingBlock:^(NSLocale *locale, NSUInteger idx, BOOL *stop) {
    [df setLocale:locale];
    [df  setTimeZone:[NSTimeZone systemTimeZone]];
    NSString *dateString=[df stringFromDate:yesterday];
    NSLog(@"%@", dateString);
}];

输出正确

Gestern
ayer
Yesterday

你的问题必须放在别的地方。

_{在命令行程序中测试}

确保在您更改设备/模拟器上的语言后，在再次打开它之前完全杀死该应用程序。

您好我为LocalTime编写此函数它将日期输入为String并转换为本地时间字符串。愿它帮助你

+(NSString*)LocalTimeWitheDateString:(NSString*)dateString{
    NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
    NSTimeZone *timeZone = [NSTimeZone timeZoneForSecondsFromGMT:0];
    [formatter setTimeZone:timeZone];
    [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
    NSDate *date =[formatter dateFromString:dateString];
    NSTimeZone *localTimeZone = [NSTimeZone localTimeZone];
    [formatter setTimeZone:localTimeZone];
    NSString *LnewTimeZoneDateString = [formatter stringFromDate:date];
    return LnewTimeZoneDateString;
}

NSDateFormatter语言环境不起作用
