I need to load a bunch of things in the beginning of my application, so I would like to implement a splash screen. I know about the Default.png screen, and I dont think that works.
Does iOS have something built-in for this? If not what is the easiest way to do so?
Does your app take too long to load and you want to do your own splash screen manually to avoid being quit by the OS on launch?
Once your app gets control, you throw up whatever you want on screen. And if that first things happens to be a full screen image view showing your splash screen while lots of things load up, well you can call that a splash screen if you like.
When loading is done, hide or destroy that image view and you are good to go.
I'm not going to provide specific code because, frankly, if you dont know how to show an image view fullscreen, you have some UIKit homework to first.
In application did load have a splash screen viewcontroller display till your app is fully loaded then dismiss the controller. The built in splash screen functionality is Default.png, and a snapshot of the application.

I have a splash screen that fades out and then the main view fades in.
The splash remains for a period of five seconds.
How can i skip this with a skip button with the same dynamic of fading out and then fading in to the main view.
If you can skip it, don't put it in in the first place.
Launch images are not designed for splash screens. They are there to give the illusion of faster loading applications. Apple's Human Interface Guidelines specifically tell you not to do this:
Avoid displaying an About window or a splash screen. In general, try to avoid providing any type of startup experience that prevents people from using your application immediately.
Avoid using your launch image as an opportunity to provide:
An “application entry experience,” such as a splash screen
An About window
Branding elements, unless they are a static part of your application’s first screen
Because users are likely to switch among applications frequently, you should make every effort to cut launch time to a minimum, and you should design a launch image that downplays the experience rather than drawing attention to it.
You are specifically required to follow the HIG by the App Store review guidelines and your application may be rejected for breaking any of the rules within it.
#Jim is correct although if you still want a skip button on your splash screen, you could create a new view controller and view and call it rootViewController and in the App Delegate specify that the app should open to rootViewController. In rootViewController, you can have a UIImageView with the splash screen image and a "skip" UIButton that transitions to the main view immediately. Hope this helps.
I have a problem that in my app i don't want to show any type of screen and when application install on device but after 2 minutes i want to show a screen. I am using following code for this
-(void)applicationDidFinishLaunching:(UIApplication *)application{
// after 30 seconds it will show a view
[self performSelector:#selector(show_view) withObject:nil afterDelay:30];
[self.window makeKeyAndVisible];
}
But when i run app on device then it show a black screen for a moment and then show a white screen. And after 30 second of white screen it add new view on current window.
But i want that when it install on device then it will start a thread in background immediately and direct show last view. Don't show any other view or screen.
How to apply that in application?
Thanks in advance...
If you looking when the application is loading that time we can't handle that moment for that you need to use the one image put that place called the splash screen.
You need to just one image which size is into iPhone is 320*460 image and give the name of the images is "Default.png". and put into resource folder.
That's better solution for that.
There is no way to achieve this. When you start an application, it is shown immediately to the user. The white screen that you see is the window, which is the first view. Even if you leave "[self.window makeKeyAndVisible]" out you will still see a black screen.
You might now think about closing down your app programmatically right after the start and automatically relaunch it 30 seconds later, but both is also not possible.
I´m doing an app for iPhone in objective-c, and before my app launches I want a splash screen to appear.
Thanks!
I think you are looking for Application Launch Images.
You just need to rename any image you want to "Default.png" and just add it in your project. That's all. Application will display that image while your app is loading.
As veredesmaralad answered, you can use an application launch image, but it's not really intended for use as a splash screen. It's intended to give the user immediate feedback that the app is launching, yet give the app some time to initialize. This image is displayed by the OS until your app puts its window on screen. The display time will vary from device to device.
If I were trying to do something more involved such as displaying the splash screen for a longer time, or animating the splash screen, I would display a view for the splash screen, then move on to the main app. I might just have my main UIViewController show the view, and then have an NSTimer tell the controller when to replace the view with the next view (e.g. the main user interface). For a more involved animated splash screen I might use a dedicated UIViewController to run that animation. Then when the animation completes I'd have the splash screen's controller load the next controller.
First off, this is called a "splash screen" and you may want to read up about it from somewhere like Wikipedia.
The answer to this question will depend heavily on what programming language you're using. If you could provide better explanation, a better answer can be given.
I have a view in my app where I use a very large photo that is Hi-Res and takes a bit of time to load. How do I put a loading screen while this is happening? The kind of loading screen with the spinning loading wheel so that the app does not look like it has frozen? Thanks in advance for any help!
Edit: Note that I am simply loading the image from the main bundle and not a URL
Check out these Open-Source activity indicators.
TDHUDProgressBar
Looks like Tweetie's/Twitter's Progress bar.
MBProgressHUD
A view that appears and contains a Activity Indicator, much like the Private Class UIProgressHUD.
Put an activity indicator (the spinning wheel) into your view and hide it when your hi-res image has finished loading.
I noticed some iPhone apps give you the title screen instantly.
Then there are some apps that gives you a black/blank screen for a brief moment.
I have the latter issue, but its lasting about 2 seconds.
I would like to display a PNG image (over 200 KB size) and a loading indicator view.
My app is based on UIView. The specified a custom UIView that basically loads and renders the said image as the wallpaper.
I tried not loading this image, yet im still getting a 2 second delay time to load.
The app delegate basically sets the view controller's view as a subview.
This delay is only seen on the device, not on the simulator.
What am i over-seeing?
If you place a Default.png file in your mainbundle, it gets displayed at launch time between the time that the app is tapped on till the time that you replace it with another view.
The reason you don't see it in the simulator is because it is faster at loading your app.
If you want to display a progress indicator, you will only be able to do it once the appDidFinishLaunching is called, but the delay that you are seeing is still there.
One trick I use is to have the same Default.png displayed again in appDidFinishLaunching and then draw a progress bar on top of that. Sure there is still the static display during the initial delay, but from there until all my initial views are loaded, I display a progress bar.
There have been some recent discussions about this on StackOverflow that you should see. And see this: How To Make Your iPhone App Launch Faster
