iPhone | How do I create a unique key from an NSTimeInterval?

Question

I need to convert an NSTimeInterval into a unique key. What is the best practice for doing this?

Thanks, Doug

Answer 1

NSTimeInterval is declared as typedef double NSTimeInterval;, it's not an object, so you can get the same value by calling different methods.

Answer 2

NSTimeInterval is just a double. This means you can use any standard hash function to generate a key.
