iOS Device Token example for Push Notifications

问题:

I need to pass through server auth method, which needs deviceToken for registration. But I have only simulators, and can't take tokens from them, and I want to send to server false token (like 000 000 000) But I don't know how many digits are there in device token. Can anyone help me out with a sample device token?

Apple Local and Remote Notification Programming Guide clearly states:

"Important: APNs device tokens are of variable length. Do not hardcode their size."

The may currently have 32 bytes but hardcoding that will make your app break in the future!

回答3:

It is 32 bytes. Written in hexadecimal they will take 64 digits.
