当用户打开应用程序时，我从服务器获得印度时间。 但如果用户从其他国家/地区打开我的应用，我必须根据该国家/地区显示时间。 怎么解决这个问题？
答案 0 :(得分：4)
嗨请检查代码：
NSDate *myDate = [NSDate date];
NSDateFormatter *f = [[NSDateFormatter alloc] init];
[f setDateStyle:NSDateFormatterLongStyle];
[f setTimeStyle:NSDateFormatterLongStyle];
[f setDateFormat:@"dd MMM YYY HH:mm"];
NSArray *timeZoneNames = [NSTimeZone knownTimeZoneNames];
for (NSString *name1 in timeZoneNames)
{
NSTimeZone *tz = [NSTimeZone timeZoneWithName:name1];
[f setTimeZone:tz];
NSLog(@"%@ = \"%@\" = %@", [tz abbreviation], name1, [f stringFromDate:myDate]);
}
输出将显示：

答案 1 :(得分：1)
我尝试将INDIAN时间转换为当地时间的其他国家。我得到了解决方案
NSString *strDate = @"19-07-2016";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"dd-MM-yyyy"];
[dateFormat setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"UTC"]];
NSDate *dateStr = [dateFormat dateFromString:strDate];
NSLog(@"The UTC format date is - %@",dateStr);
[dateFormat setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
[dateFormat setTimeZone:[NSTimeZone systemTimeZone]];
NSString *strLocalDate = [dateFormat stringFromDate:dateStr];
NSLog(@"The Local date is - %@",strLocalDate);
打印结果
The UTC format date is - 2016-07-19 00:00:00 +0000
The Local date is - 2016-07-19 05:30:00

试试这个......
-(NSString *)getUTCFormateDate:(NSDate *)serverDate
{
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"UTC"];
[dateFormatter setTimeZone:timeZone];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
NSString *dateString = [dateFormatter stringFromDate:serverDate];
return dateString;
}
-(NSString *)getLocalDateTimeFromUTC:(NSString *)strDate
{
NSDateFormatter *dtFormat = [[NSDateFormatter alloc] init];
[dtFormat setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
[dtFormat setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"UTC"]];
NSDate *aDate = [dtFormat dateFromString:strDate];
[dtFormat setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
[dtFormat setTimeZone:[NSTimeZone systemTimeZone]];
return [dtFormat stringFromDate:aDate];
}

// Gives Date in UTC
NSDate *currentDate = [[NSDate alloc] init];
// Timezone For India
NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"Asia/Kolkata"];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeZone:timeZone];
[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"];
NSString *localDateString = [dateFormatter stringFromDate:currentDate];
