Print CMTime in objective C

I have some experience of swift, but zero knowledge on objective C
I need to print a timestamp in the console,
here it is:

  CMTime timeStamp = CMTimeMake(frame.timeStampNs / rtc::kNumNanosecsPerMillisec, 1000);

I added something like that:

NSLog(@timeStamp);

But it’s failed, I need to print something like that in swift:

print("Timestamp: \(timeStamp)"

Could you please tell me how to do it on objective c?

Thanks

>Solution :

Use the format specifier %f for 64-bit floating-point numbers (double)

NSLog("Timestamp: %f", CMTimeGetSeconds(timeStamp));
