iPhone:如何获得当前毫秒?
问题描述:
获取当前系统时间毫秒的最佳方法是什么?
What is the best way to get the current system time milliseconds?
答
[[NSDate date] timeIntervalSince1970];
它将自纪元以来的秒数作为双精度返回。我几乎可以肯定你可以从小数部分访问毫秒。
It returns the number of seconds since epoch as a double. I'm almost sure you can access the milliseconds from the fractional part.
