Read the Apple iPhone Human Interface Guidelines (HIG). The "splash screen" isn't supposed to be for branding or displaying a logo, it's supposed to look like the default condition of the app so it appears to start up quickly.

Making it stay there for longer would be a violation of the HIG.

blocks|key|1625095|text|要做到这一点，最简单的方法是创建一个镜像为您的Default.png的UIImageView。在applicationDidFinishLaunching:方法中，将图像视图添加到窗口中，并在希望闪屏消失时将其隐藏。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1625096|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The simplest way to do this is to create a UIImageView who's image is your Default.png. In your applicationDidFinishLaunching: method, add that image view to your window, and hide it when you'd like your splash screen to go away.

blocks|key|1410673|text|我需要这样做，以阻止显示表视图，直到通过网络加载数据为止。我使用了我在这里找到的一个变体：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1410674|http://michael.burford.net/2008/11/fading-defaultpng-when-iphone-app.html|offset|length|1410675|在App+Delegate的界面中：|1410676|@interface+AppDelegate+:+NSObject+

I needed to do this to block showing a table view until the data was loaded over the network. I used a variation of one I found here:

In the interface of your App Delegate:

<pre><code>
@interface AppDelegate : NSObject 
{
 UIImageView *splashView;
}
</code></pre>

In the implementation:

<pre><code>
@implementation AppDelegate
- (void)applicationDidFinishLaunching:(UIApplication *)application {


 // After this line: [window addSubview:tabBarController.view];

 splashView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
 splashView.image = [UIImage imageNamed:@"Default.png"];
 [window addSubview:splashView];
 [window bringSubviewToFront:splashView];

 // Do your time consuming setup

 [splashView removeFromSuperview];
 [splashView release];
}

</code></pre>

Make sure you have a Default.png in the resources

Make your app take longer to load.

In all seriousness, Paul Tomblin is correct that this usually isn't a good idea. Default.png is a mechanism intended to make your app appear to load faster by holding an "empty" screenshot. Using it for a splash screen is a minor abuse, but intentionally making that splash screen appear for longer than it needs to is almost sick. (It will also degrade your user experience. Remember, every second the splash screen is visible is a second that the user is impatiently staring at your logo, swearing they'll switch to the first decent competitor they can find.)

If you're trying to cover for some sort of secondary loading--for example, if the interface has loaded and you're just waiting to get some data from the network--then it's probably okay, and Ben Gottlieb's approach is fine. I'd suggest adding a progress bar or spinner to make it clear to the user that something really is going on.

There are many options already posted here, but I ran into cocoapod today that allows you to display the contents of your <code>LaunchScreen.xib</code> as the initial view controller:

<a href="https://github.com/granoff/LaunchScreen" rel="nofollow">https://github.com/granoff/LaunchScreen</a> (Also see this <a href="http://blog.hawkimedia.com/2014/10/dynamic-interactive-launch-screens/" rel="nofollow">blog post from the author with more implementation details</a>.)

This seems like a fairly straight-forward way to do this, and better than the vast majority of answers posted here. (Of course it wasn't possible until the introduction of <code>LaunchScreen</code> files in the first place.) It is possible to display an activity indicator (or anything else you want) on top of the view.

As for why you would want to do this, I'm surprised that no one has mentioned that there are often publisher and/or partner requirements around this sort of thing. It's VERY common in games, but advertising-funded applications as well.

Also note that this does act counter to the HIG, but then so does waiting to load any content after your application launches. Remember that the HIG are guidelines, and not requirements.

One final note: It's my personal opinion, that any time an initial screen like this is implemented, you should be able to tap to dismiss it.

There is default image (default.png) is shown when you start your app.

So you can add a new viewcontroller which will display the that default image in the application didFinishLoading.

So by this logic you display the default image for a bit longer.

How can I display a splash screen for a longer period of time than the default time on an iPhone?
