Ios – iPhone: How to get current milliseconds

current-timeiosiphonetimetimestamp

What is the best way to get the current system time milliseconds?

Best Solution

If you're looking at using this for relative timing (for example for games or animation) I'd rather use CACurrentMediaTime()

double CurrentTime = CACurrentMediaTime();

Which is the recommended way; NSDate draws from the networked synch-clock and will occasionally hiccup when re-synching it against the network.

It returns the current absolute time, in seconds.


If you want only the decimal part (often used when syncing animations),

let ct = CACurrentMediaTime().truncatingRemainder(dividingBy: 1)
