When app start up, use splashView with ActivityIndicatorView

Add SplashScreenVC class in the project.

Use the below code to replace the original code in yourAppDelegate.m:

- (void)applicationDidFinishLaunching:(UIApplication *)application

{

    SplashScreenVC *splashScreenVC = [[SplashScreenVC alloc] initWithNibName:@"SplashScreenVC" bundle:nil];

    self.window.rootViewController = splashScreenVC;

    [self.window makeKeyAndVisible];

}

In SplashScreenVC, import yourAppDelegate.h and add the below code:

-(void)viewDidAppear:(BOOL)animated{

    [super viewDidAppear:animated];

    [self performSelector:@selector(gotoRootVC) withObject:nil afterDelay:1.0];

}

-(void)gotoRootVC

{

    

    SQLiteTutorialAppDelegate *delegate = (SQLiteTutorialAppDelegate *)[UIApplication sharedApplication].delegate;

    delegate.window.rootViewController = delegate.tabBarController;

    [delegate.window makeKeyAndVisible];

}

-(void)viewDidLoad

{

    CGRect r = [UIScreen mainScreen].applicationFrame;

    UIView *activityView = [[[UIView alloc] initWithFrame:r] autorelease];

    self.view = activityView;

    

    activityView.backgroundColor = [UIColor blackColor];

    activityView.alpha = 0.5;

    

    UIImageView *imgView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yourImage.png"]] autorelease];

    [activityView addSubview:imgView];

    

    CGRect wheelR = CGRectMake(r.size.width / 2 - 12, r.size.height / 2 - 12, 24, 24);

    UIActivityIndicatorView *activityWheel = [[UIActivityIndicatorView alloc] initWithFrame:wheelR];

    activityWheel.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite;

    activityWheel.autoresizingMask = (UIViewAutoresizingFlexibleLeftMargin |

                                      UIViewAutoresizingFlexibleRightMargin |

                                      UIViewAutoresizingFlexibleTopMargin |

                                      UIViewAutoresizingFlexibleBottomMargin);

    [activityWheel startAnimating];

    [activityView addSubview:activityWheel];

}
