iphone - Retaining state of a user variable in Cocoa -

-

What is the correct way to define a user input variable, so it retains its value after the user returns. I have a textView where the user enters a description, and I want to clear the contents of textview, but to keep the user who is logged in first. Define an NSString in the header of your UIViewController, make your UIViewController a UITextViewDelegate (@interface MyViewController: UIViewController {), and create your own UIViewController.

Set up the representative property of the UITextView. Then, your - Viewed changes in text (zero) text: (UITextView *) textView method, set the NSString variable for your UITextView text when the user deletes the focus from your UITextView, Clears the contents, and the NSString variable has been omitted from the text which was written before the clearing.

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP.
