Question

I’m creating a application with an sqlite database. I update the database with information retrieved from a web service. I call the web service from AppDelegate like this:

-(void)applicationDidBecomeActive:(UIApplication *)application{

    // get new information from web service
    // update sqlite database

}

The web service can take quite a long time so I want to add a UIActivityIndicatorView to whatever viewController that is active. And of course, remove it when then update is done.
Ideas?

Answer 1

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    testView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 420, 480)];
    testView.backgroundColor = [UIColor redColor];
    [self.window.rootViewController.view addSubview:testView];
}

Then whenever you are done do:

[testView removeFromSuperview];
