In my app I update a textView programmatically. I actually loop through a dataset from a SQLITE3 DB and show a specific text for a given time. Then I would like to show the text from the next dataset record and so forth. I have been browsing through all kind of forums and the apple doc as well, but could not find anything like a repaint, refresh, updateTextView or so command.
I am dealing with long strings, why I thought the UITextView would be the best way to display. However, if another UI Class, like the UITextField or UILabel would be better and easier to achieve what I am looking for, I would also use that. No problem.

    What exactly is your question?

    Are you asking how to set text in a UITextView? Just use its text property:

    someTextView.text = @"Some Text";

    Are you asking if it’s “better” to use a UILabel or UITextField? That’s a subjective question. It depends on how your app is designed and what makes the most sense for presenting textual information. (Presenting formatted HTML in a UIWebView is another option.)

    Once you set the text of any of these built-in classes, it will know to update/redraw itself. You don’t need to set text and then trigger the redrawing or “repainting” manually.
