代码：

NSDateFormatter *fmt = [[NSDateFormatter alloc] init]; 
    fmt.dateFormat = @"yyyy-MM-dd HH:mm:ss"; 
    NSDate *utc = [fmt dateFromString:strTime]; 

    NSTimeZone *tz = [NSTimeZone defaultTimeZone]; 
    NSInteger seconds = [tz secondsFromGMTForDate: utc]; 

    NSDate *localdate = [NSDate dateWithTimeInterval:seconds sinceDate:utc]; 
    NSString *local = [fmt stringFromDate:localdate]; 
    NSLog(@"local time%@", local); 

    NSDate *localDate = [fmt dateFromString:local];

尝试了这一点：

NSDateFormatter *fmt = [[NSDateFormatter alloc] init]; 
fmt.dateFormat = @"yyyy-MM-dd HH:mm:ss"; 
NSDate *utc = [fmt dateFromString:<Your_UTC_String>]; 
fmt.timeZone = [NSTimeZone systemTimeZone]; 
NSString *local = [fmt stringFromDate:utc]; 
NSLog(@"%@", local);
