Question

In my app when I download something from service, I show progress indicator:

 - (void)setupProgressIndicator {
    MBProgressHUD *progressHUD = [[MBProgressHUD alloc] initWithView:self.view];
    [self.view addSubview:progressHUD];
    self.progressIndicator = progressHUD;
    [progressHUD release];
 }

[self.progressIndicator show:YES];

My view has Navigation Bar which I setup in my AppDelegate, and when indicator is shown, I still can tup on Navigation Bar Buttons…Can MBProgressHUB cover whole screen ??? Because I don’t want to disable buttons on sync start and than make them enable on sync finish…I think indicator should cover whole screen. Any ideas ? Thanks…

Here is my implementation use it if you want
Put it in appDelegate and use from anywhere in the application.

#pragma mark -
#pragma mark Waiting View
- (void)showWaitingView {

    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

    CGRect frame = CGRectMake(90, 190, 32, 32);
    UIActivityIndicatorView* progressInd = [[UIActivityIndicatorView alloc] initWithFrame:frame];
    [progressInd startAnimating];
    progressInd.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;

    frame = CGRectMake(130, 193, 140, 30);
    UILabel *waitingLable = [[UILabel alloc] initWithFrame:frame];
    waitingLable.text = @"Processing...";
    waitingLable.textColor = [UIColor whiteColor];
    waitingLable.font = [UIFont systemFontOfSize:20];;
    waitingLable.backgroundColor = [UIColor clearColor];
    frame = [[UIScreen mainScreen] applicationFrame];
    UIView *theView = [[UIView alloc] initWithFrame:frame];
    theView.backgroundColor = [UIColor blackColor];
    theView.alpha = 0.7;
    theView.tag = 999;
    [theView addSubview:progressInd];
    [theView addSubview:waitingLable];

    [progressInd release];
    [waitingLable release];

    [window addSubview:[theView autorelease]];
    [window bringSubviewToFront:theView];
    [pool drain];
}

- (void)removeWaitingView {
    UIView *v = [window viewWithTag:999];
    if(v) [v removeFromSuperview];

}
