iOS格式字符串分为秒和秒 [英] iOS Format String into minutes and seconds

问题描述

我收到了来自YouTube JSONC api的字符串，但持续时间是一个完整的数字，即2321而不是23:21或2而不是0:02。我该如何解决此问题？

I am receiving a string from the YouTube JSONC api, but the duration is coming as a full number i.e 2321 instead of 23:21 or 2 instead of 0:02. How would I go about fixing this?

JSON C

编辑：

int duration = [videos valueForKey:@"duration"];
int minutes = duration / 60;
int seconds = duration % 60;

NSString *time = [NSString stringWithFormat:@"%d:%02d", minutes, seconds];

推荐答案

假设持续时间值实际上是以秒为单位的持续时间，然后你可以计算分钟数和秒数，然后将它们格式化为一个字符串。

Assuming the duration value is really the duration in seconds, then you can calculate the number of minutes and seconds and then format those into a string.

int duration = ... // some duration from the JSON
int minutes = duration / 60;
int seconds = duration % 60;

NSString *time = [NSString stringWithFormat:@"%d:%02d", minutes, seconds];
