how to hide the PLAY_SESSION value?

You cannot hide them, they are stored in cookies as strings.
Instead you can store session-data in the database and then trough the session pass only unique ID of the DB record, that's definitely safer approach and more comfortable as you're not limited by the cookie size.

I wrote this code below to get the length of a textfield and pop up an alert after it, it keeps ask me to declare the length in the #interface, how could I do that?
if ([myTextField length]<=0)
Maybe you should use [myTextField.text length]?
If this wasn't the problem then maybe you could post some codes and the error message to get more clarification ;D

How can an application set a ringtone on iPhone?
This feature is not supported in the API currently since it could be used to set the ringtone to something that the user did not intend to set it to. If you'd like to see it added, best thing to do is submit a feature request to Apple.
