Comments on: UIAlertView without Buttons – Please Wait Dialog

Is there a way to dismiss the dialog on a delay? Or, put differently, I’d like to use

[alert performSelector:withObject:afterDelay:]

But withObject: only accepts one object, and dismissWithClickedButtonIndex:animated: demands two. I’ve run into this problem before with perform:withObject: when there is more than one argument being passed to the selector.

Any hints?

Hmm. Just had a thought–can I pass an array of objects? Will performSelector grok it and pull the appropriate data? Or maybe a dictionary with the individual selectors as keys? I’ll experiment.

using the alert the user has the impression that the app froze. Since the alert is loaded with a second or two delay and the screen became whiter on the center.
The alert is loaded before reading from the web

To dismiss the alert, you call the method dismissWithClickedButtonIndex of the Alert object and you must provide an index value as a value for the dismissWithClickedButtonIndex parameter.

great tip! But I didn’t understand how the “dismissWithClickedButtonIndex” accepts a button Index when there are no buttons in the alertView?

I can’t dismiss the alert from XMLParser delegate method :

- (void)parserDidEndDocument:(NSXMLParser *)parser {
[alert dismissWithClickedButtonIndex:0 animated:YES];
[tableView reloadData];
}
the UIAlertView *alert is defined in the header file .

Just great. Also wondering if there is a way to set the dialog to be on the screen for a minimum amount of time in case the activity we are undertaking is so short that the user can’t read the message …

You don’t need to autorelease a UIAlertView. Just release it after you do “show”.

This looks like exactly what I am looking for.

One question though… in a few other places they suggest that modifying the standard alert view can get your app rejected. Has anyone had any problems with this or perhaps could offer further insight into the UI programming guidelines?

Many thanks.
