How can I display a splash screen for longer on an iPhone?

Question

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

Answer 1

Swift 2.0

Use following line in didFinishLaunchingWithOptions: delegate method:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    NSThread.sleepForTimeInterval(5.0)
    return true
}

But I recommend this:

Put your image in a UIImageView full screen as a subview on the top of your main view thus covering your other UI. Set a timer to remove it after some seconds (possibly with effects) now showing your application.

import UIKit
    class ViewController: UIViewController
    {
        var splashScreen:UIImageView!
        override func viewDidLoad()
        {
            super.viewDidLoad()
            self.splashScreen = UIImageView(frame: self.view.frame)
            self.splashScreen.image = UIImage(named: "Logo.png")
            self.view.addSubview(self.splashScreen)
    
            var removeSplashScreen = NSTimer.scheduledTimerWithTimeInterval(3.0, target: self, selector: "removeSplashImage", userInfo: nil, repeats: false)
        }
        func removeSplashImage()
        { 
            self.splashScreen.removeFromSuperview()
        }
    }
