I am having a terrible time trying to do something that should be easy. I have a NSNumber value of 32025.89 seconds. I need to represent that in Hours, Minutes, Seconds. Is there a method that spits that out? I can't seem to find a proper formatter.

推荐答案

您是否尝试过从中创建 NSDate 并使用 NSDateFormatter 打印它?

Have you tried creating an NSDate from that and printing that using an NSDateFormatter?

NSDate *date = [NSDate dateWithTimeIntervalSince1970:[theNumber doubleValue]];
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"HH:mm:ss"];
NSLog(@"%@", [formatter stringFromDate:date]); 
[formatter release];

如果您需要小时、分钟和秒的单独值，请按照 nall 的建议使用 NSDateComponents.

If you need the individual values for hours, minutes, and seconds, use NSDateComponents as suggested by nall.

如果 NSNumber 表示超过一天，上面的将不会打印正确的数量.它可以是 1 天 1 小时，它只会打印 01:00:00.在这种情况下，您应该手动计算小时、分钟和秒.

The above won't print the correct amounts if the NSNumber represents more than one day. It could be 1 day and 1 hour, and it would only print 01:00:00. In such a case you should calculate hours, minutes and seconds manually.
