我需要将我在NSString中的某些日期转换为NSString格式：yyyy-MM-dd HH：mm：ss zzz
我写这段代码：
我写这段代码：
日期输入：日期—> 27/03/2012
-(NSString *)setDateStringFormat:(NSString *)date
{
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"dd/MM/yyyy"];
[formatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
//[formatter setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
NSDate *dateFormatted = [formatter dateFromString:date];
[formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss zzz"];
[formatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
return [formatter stringFromDate:dateFormatted];
}
输出：2012-03-27 00:00:00 GMT
你们都可以看到我在格林尼治标准时间而不是在UTC中获得了日期
有人有想法吗？
解决方法
试试这个方法..
-(NSString *)getUTCFormateDate:(NSString *)localDate
{
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd/MM/yyyy"];
NSDate *dateFormatted = [dateFormatter dateFromString:localDate];
NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"UTC"];
[dateFormatter setTimeZone:timeZone];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
NSString *dateString = [dateFormatter stringFromDate:dateFormatted];
[dateFormatter release];
return dateString;
}
