UIProgressView in UIAlertView?

Question

UIProgressView in UIAlertView?

While I'm exporting data to a server I'd like to show some sort of progress bar. So far I haven't thought of a decent way to handle that, other than to pop up an alert view with a progress bar. Except I don't see anything in UIAlertView for adding anything other buttons.

I googled and found an o'reilly article, but it appears to be rather out of date. At least, it doesn't work for me. I'm pretty sure I've seen another app do this, but I can't remember which one off the top of my head.

Any suggestions? Is there a better way to do this?

I face the same problem , I think the API does not provides such feature , I think it has to use a subView to show the progress on the view . as well as alert message and button . I think it can be a component class .

You just need to add a UIProgressView to your UIAlertView:
This snippet also creates an UIActivityIndicatorView if needed.


- (void) createProgressionAlertWithMessage:(NSString *)message withActivity:(BOOL)activity
{
 progressAlert = [[UIAlertView alloc] initWithTitle: message
 message: @"Please wait..."
 delegate: self
 cancelButtonTitle: nil
 otherButtonTitles: nil];
 
 
 // Create the progress bar and add it to the alert
 if (activity) {
 activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
 activityView.frame = CGRectMake(139.0f-18.0f, 80.0f, 37.0f, 37.0f);
 [progressAlert addSubview:activityView];
 [activityView startAnimating];
 } else {
 progressView = [[UIProgressView alloc] initWithFrame:CGRectMake(30.0f, 80.0f, 225.0f, 90.0f)];
 [progressAlert addSubview:progressView];
 [progressView setProgressViewStyle: UIProgressViewStyleBar];
 }
 [progressAlert show];
 [progressAlert release];
}

Hi

I was using the code mentioned in this post with some modifications. If I add a Cancel button or any other button to the alert view along with the progress view, the button clicks stop working! Is there a way around this? I want the user to be able to cancel an upload! Please help!

Did you set the button's action properly? I'm guessing that if you manually added the button to the view then you won't get the button click through the regular delegate method.

You just have to change the subview rect that you're drawing the UIProgressView in, otherwise the subview covers the button on the UIAlertView and won't allow the user to click it.

Try something like this:

progressView = [[UIProgressView alloc] initWithFrame:CGRectMake(30.0f, 68.0f, 225.0f, 13.0f)];
