Splash Screen Series

[juna1418]

Hi, I'm quite new to the IPhone Development, so I'd be extremely grateful for any kind of advice My game app uses a tabbar and so far has a single splash screen. Now I'd like to add at least two other images/text as intro, but so far couldn't come up with any idea that makes sense...
Is it possible to make use of an array and if how could the code look like? Or is there another way?

What I usually do is overlay 2 images in my application in interface builder. I then run 2 timers. One is to fade out the first image, the other is to fade out the second image. Additionally, you can make the 2 images act as buttons so users cannot run your interface through the image and upon tapping the image, the corresponding image is faded juts like if the timer had faded it.

I'd like to do the same, but do so in the launch time...

For example, say I know that my app takes about 5 seconds to load. I'd like to display a splash for 3 seconds, then a launch image for the remainder...how would I do that (if at all)? Obviously, I don't want to prolong the loading time simply for a splash screen—it detracts from the user experience.

-(void)viewDidLoad {
	
	UIImage *mySplashImage = [UIImage imageNamed:@"myImage.png"];
	myImageView = [[UIImageView alloc] initWithImage:mySplashImage];
	myImageView.frame = CGRectMake(0, 0, 320, 480);
	[self.view addSubview:myImageView];
	
	NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(hideSplashScreen) userInfo:nil repeats:NO];
	timer = nil;
	
}

-(void)hideSplashScreen {
	
	myImageView.alpha = 0.0;
	
	NSLog(@"hidden");
	
}

This creates an image right after the launch screen, waits 2 seconds, then goes and hides it again.

To hide 2 images, try this:

-(void)viewDidLoad {
	
	UIImage *mySplashImage = [UIImage imageNamed:@"image.png"];
	myImageView = [[UIImageView alloc] initWithImage:mySplashImage];
	myImageView.frame = CGRectMake(0, 0, 320, 480);
	
	UIImage *mySplashImage1 = [UIImage imageNamed:@"anotherImage.png"];
	myImageView1 = [[UIImageView alloc] initWithImage:mySplashImage1];
	myImageView1.frame = CGRectMake(0, 0, 320, 480);
	[self.view addSubview:myImageView1];
[self.view addSubview:myImageView];
	
	NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(hideSplashScreen) userInfo:nil repeats:NO];
	timer = nil;
	
	NSTimer *timer1 = [NSTimer scheduledTimerWithTimeInterval:5 target:self selector:@selector(hideSecondSplash) userInfo:nil repeats:NO];
	timer1 = nil;
	
}

-(void)hideSplashScreen {
	
	myImageView.alpha = 0.0;
	
	NSLog(@"hidden");
	
}

-(void)hideSecondSplash {
	
	myImageView1.alpha = 0.0;
	
}

Thanks a lot I tried it, but there still seems to be a small problem, since beside the first image nothing will show up . There seems to be some conflict with my main TabBarView: the screen turns black and my Main-TabBarView won't show. I wonder what kind of mistake I made..

Oops, I was making the second image disappear later even though it was the image on top. Try the new code. It makes the images both appear on the load, then the one disappears after 2 seconds and the other goes after 3 additional seconds. I have tested it and it is working fine.

I am trying to follow you on this info, but I am not able to get this to work. Using just a single image, does this code go in the AppDelegate.m file? And "myImageView" would be what? a xib with a UIImage in it?

Please help me to understand how you are doing this....I am trying hard to learn as best I can.

Thanks

You will put this in your viewController (RootViewController) or the one that you first see when you open your application.

Now, add 2 imageView declarations in your .h file. This allows us to make the imageViews disappear. (UIImageView *imageView

Now, you can input the code, and import your images into the Resources folder in your application. You can then select the image that you want to display by adjusting the code that says YourImageHere.png.

It will work after that.

Hmm, unfortunately it didn't work that way for me. I tried several alterations, but if at all, there was just the usual appearance of my good old TabBar...
other than that the console gave just some remarks about not fitting Objective-C and others
in a somewhat different form, wouldn't it fit in here?:

- (BOOL)applicationUIApplication *)application didFinishLaunchingWithOptionsNSDictionary *)launchOptions {

[window addSubview:rootTabBarController.view];
[window makeKeyAndVisible];

....

I do not usually put stuff into the AppDelegate. You want to put it into the ViewController.
