iphone-UIAlertview-UIIndicatorview

i Am New In Iphone development. i have one form in which for display data I am calling a webservice. When that service is called it parses from other file, And Page Navigates To 'Send Page' In Which These Data Is Displayed In a UITableview.

i am also using uiAtertview And UIIndicatorview Both For Displaying that the process is going. But Problem Is When I Click On Button I Call UIAtertView + UIIndicator But It Is Not getting Displayed And Data is Also Not getting Displayed,,,

My Code Is

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Configuring Preferences\nPlease Wait.." message:nil delegate:nil cancelButtonTitle:nil otherButtonTitles:nil,nil];
[alert show];


UIActivityIndicatorView *indicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

// Adjust the indicator so it is up a few pixels from the bottom of the alert
indicator.center = CGPointMake(alert.bounds.size.width / 2, alert.bounds.size.height - 50);
[indicator startAnimating];
[alert addSubview:indicator];
[indicator release];

self.ResultPage = [[ResultPage alloc] init];
self.title=@"    Search    ";

// Here My Webservice Is Call From Another ViewController Class And That Class Display Data //InTo UITableVIew

[self.ResultPage GetSearchResult:StrBookId : txtFPrice.text :txtTprice.text];
[alert dismissWithClickedButtonIndex:0 animated:YES];
[self.navigationController pushViewController: _ResultPage animated:YES];

Please Suggest Me....

Thanx

You can add activity indicator in alert view and show that alert view when you call web service.I also do the same when I call webservice. it locks the view so that the user cannot click anything and look wise also seems to be fine and indicating user that something is going in process.

in .h file

UIAlertView *progressAlert;

in .m file

-(void)showAlertMethod

{
    NSAutoreleasePool *pool1=[[NSAutoreleasePool alloc]init];           
progressAlert = [[UIAlertView alloc] initWithTitle:@"Uploading please wait...\n" message:@"" delegate:nil cancelButtonTitle:nil otherButtonTitles:nil];
    CGRect alertFrame = progressAlert.frame;
    UIActivityIndicatorView* activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
    activityIndicator.frame = CGRectMake(135,alertFrame.size.height+55, alertFrame.size.width,30);
    activityIndicator.hidden = NO;
    activityIndicator.contentMode = UIViewContentModeCenter;
    [activityIndicator startAnimating]; 
    [progressAlert addSubview:activityIndicator];
    [activityIndicator release];
    [progressAlert show];
    [pool1 release];

}
-(void)dismissAlertMethod
{
    NSAutoreleasePool *pool2=[[NSAutoreleasePool alloc]init];
    [progressAlert dismissWithClickedButtonIndex:0 animated:YES];
    [pool2 release];
}

call the method according to your requirements. I call the methods in this way:-

[NSThread detachNewThreadSelector:@selector(showAlertMethod) toTarget:self withObject:nil];

[NSThread detachNewThreadSelector:@selector(dismissAlertMethod) toTarget:self withObject:nil];
