UIAlertView在应用加载时显示，打开

Question

如何在应用打开时显示提醒视图，加载...

就像每次用户打开应用程序一样，他会看到警报......

Answer 1

在以下appDelegate方法中编写alert语句，

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
      UIAlertView *alert_View = [[[UIAlertView alloc] initWithTitle:@"Your Title" message:@"Your Message" delegate:self cancelButtonTitle:nil otherButtonTitles:@"YES",@"NO",nil] autorelease];
    [alert_View show];
}

Answer 2

在applicationDidFinishLaunching：和applicationWillEnterForeground中的应用程序委托类中显示alertview：

Answer 3

@Rafeel将此UIAlertView放入AppDelegate的didFinishLaunchingWithOptions方法中，当您的应用启动时，您将始终获得UIAlertView

UIAlertView *confirmAlertView=[[UIAlertView alloc]initWithTitle:@"Saved" message:@"Want to save!!" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Cancel",nil];
    [confirmAlertView show];
    [confirmAlertView release];
