UIView Animation, activity indicator

For all those who needed this, and i know there were many…
(Made on Xcode version 4.2.1)


In the AppDelegate.h add this:

@property (nonatomic, strong) UIImageView *splashView;

In the AppDelegate.m add this:

On the top of the page of cours @synthesize splashView;
And then:

- (void) splashFade
    splashView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0, 320, 480)];
    splashView.image = [UIImage imageNamed:@"Default.png"];
    [_window addSubview:splashView];
    [_window bringSubviewToFront:splashView];
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:2.0];
    [UIView setAnimationDelay:2.5];
    [UIView setAnimationTransition:UIViewAnimationTransitionNone forView:_window cache:YES];
    [UIView setAnimationDelegate:self]; 
    [UIView setAnimationDidStopSelector:@selector(startupAnimationDone:finished:context:)];
    splashView.alpha = 0.0;
    [UIView commitAnimations];

    //Create and add the Activity Indicator to splashView
    UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
    activityIndicator.alpha = 1.0;
    activityIndicator.center = CGPointMake(160, 360);
    activityIndicator.hidesWhenStopped = NO;
    [splashView addSubview:activityIndicator];
    [activityIndicator startAnimating];

- (void)startupAnimationDone:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
    [splashView removeFromSuperview];

The [UIView setAnimationDelay:2.5] is responsible for how long the splashView will be in front by the delay time you choose.

You can change the position of the indicator by changing the nubmers of x/y in:
activityIndicator.center = CGPointMake(160, 360);

At last, under the methode:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

Just add this:

[self performSelector:@selector(splashFade) withObject:nil];

And there you go 🙂
Hope it helped.

Have a nice programming….
