一、将字符串时间转化为NSDate,并打印
1 NSString *string = @"2013-08-12 20:13:43"; 2 3 NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; 4 //格式一定要一致,否则无法转换 5 formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss"; 6 7 NSDate *date = [formatter dateFromString: string]; 8 NSLog(@"\n%@", date);
二、格式化NSDate,转换成字符串并打印
1 NSDate *date = [NSDate date]; 2 NSString *time; 3 NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 4 dateFormatter.dateFormat = @"yyyy-MM-dd HH:mm:ss"; 5 time = [dateFormatter stringFromDate:date]; 6 NSLog(@"\n%@", date);
