有類似的問題很多答案，只是張貼這個答案櫃面你還沒有找到它

NSString *inputString = @"2013-05-11 05:54:07.589698"; 

NSDateFormatter *dateFormatter = [NSDateFormatter new]; 
[dateFormatter setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"UTC"]]; 
[dateFormatter setLocale:[[NSLocale alloc]initWithLocaleIdentifier:@"en_US_POSIX"]]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss.SSSSSS"]; 

NSDate *date = [dateFormatter dateFromString:inputString]; 
[dateFormatter setDateFormat:@"HH:mm:ss"]; 
NSString *timeString = [dateFormatter stringFromDate:date]; 

NSLog(@"%@",timeString);
