通过按钮打开 AppStore

最佳答案

Here. But I highly suggest you learn the basics of Swift!

UIApplication.sharedApplication().openURL(NSURL(string: "itms://itunes.apple.com/de/app/x-gift/id839686104?mt=8&uo=4")!)

If you wanna open the AppStore in Swift 5:

if let url = URL(string: "itms-apps://itunes.apple.com/app/id1629135515") {
UIApplication.shared.open(url)
}

Since other answers didn't work for me (Swift, Xcode 6.1.1) here I post my solution:

var url  = NSURL(string: "itms://itunes.apple.com/de/app/x-gift/id839686104?mt=8&uo=4")


if UIApplication.sharedApplication().canOpenURL(url!) {
UIApplication.sharedApplication().openURL(url!)
}

小开

    var url  = NSURL(string: "itms-apps://itunes.apple.com/app/id1024941703")
if UIApplication.sharedApplication().canOpenURL(url!) == true  {
UIApplication.sharedApplication().openURL(url!)
}

I use this combination, its better for rate/shopping.

(partially from here)

    @IBAction func rateMe(sender: AnyObject) {
if #available(iOS 8.0, *) {
openStoreProductWithiTunesItemIdentifier("107698237252");
} else {
var url  = NSURL(string: "itms://itunes.apple.com/us/app/xxxxxxxxxxx/id107698237252?ls=1&mt=8")
if UIApplication.sharedApplication().canOpenURL(url!) == true  {
UIApplication.sharedApplication().openURL(url!)
}


}
}
func openStoreProductWithiTunesItemIdentifier(identifier: String) {
let storeViewController = SKStoreProductViewController()
storeViewController.delegate = self


let parameters = [ SKStoreProductParameterITunesItemIdentifier : identifier]
storeViewController.loadProductWithParameters(parameters) { [weak self] (loaded, error) -> Void in
if loaded {
// Parent class of self is UIViewContorller
self?.presentViewController(storeViewController, animated: true, completion: nil)
}
}
}
func productViewControllerDidFinish(viewController: SKStoreProductViewController) {
viewController.dismissViewControllerAnimated(true, completion: nil)
}

don't forget to import and delegate:

import StoreKit


class RateMeViewController: UIViewController, SKStoreProductViewControllerDelegate {

Swift 3 Syntax and improved with an 'if let'

if let url = URL(string: "itms-apps://itunes.apple.com/app/id1024941703"),
UIApplication.shared.canOpenURL(url){
UIApplication.shared.openURL(url)
}

UPDATE 7/5/17 (Thank you Oscar for pointing this out):

if let url = URL(string: "itms-apps://itunes.apple.com/app/id1024941703"),
UIApplication.shared.canOpenURL(url)
{
if #available(iOS 10.0, *) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
UIApplication.shared.openURL(url)
}

Check newer app update available on iTunes in Swift 3

let currentAppVersion = Bundle.main.infoDictionary
Alamofire.request("http://itunes.apple.com/jp/lookup/?id=548615", method: .get, parameters: nil, headers: nil).responseJSON { response in
if let value = response.result.value as? [String: AnyObject] {
let versionNum = value["results"]?.value(forKey: "version") as? NSArray
if versionNum?[0] as! String != currentAppVersion?["CFBundleShortVersionString"] as! String {
self.alertForUpdateApp()
}
}
}


func alertForUpdateApp() {


let alertController = UIAlertController(title: "Update Available", message: "There is a newer version of this app available", preferredStyle: .alert)
let alertActionCancel = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
let alertActionUpdate = UIAlertAction(title: "Update", style: .default, handler: { _ in
if let url = URL(string: Constants.API_REDIRECT_TO_ITUNES),
UIApplication.shared.canOpenURL(url){
UIApplication.shared.open(url, options: [:], completionHandler: nil)


}
})


alertController.addAction(alertActionCancel)
alertController.addAction(alertActionUpdate)


let pushedViewControllers = (self.window?.rootViewController as! UINavigationController).viewControllers
let presentedViewController = pushedViewControllers[pushedViewControllers.count - 1]


presentedViewController.present(alertController, animated: true, completion: nil)


}

Swift 4 with completion handler:

Make sure to update your id in the appStoreUrlPath

func openAppStore() {
if let url = URL(string: "itms-apps://itunes.apple.com/app/id..."),
UIApplication.shared.canOpenURL(url){
UIApplication.shared.open(url, options: [:]) { (opened) in
if(opened){
print("App Store Opened")
}
}
} else {
print("Can't Open URL on Simulator")
}
}

For me didn't worked one of this answers. (Swift 4) The app always opened the iTunes Store not the AppStore.

I had to change the url to "http://appstore.com/%Appname%" as described at this apple Q&A: https://developer.apple.com/library/archive/qa/qa1633/_index.html

for example like this

private let APPSTORE_URL = "https://appstore.com/keynote"
UIApplication.shared.openURL(URL(string: self.APPSTORE_URL)!)

(remove spaces from the app-name)

For the new AppStore, simply open your app's link on AppStore and replace the https scheme to itms-apps scheme. Example on Swift 4:

if let url = URL(string: "itms-apps://itunes.apple.com/us/app/my-app/id12345678?ls=1&mt=8") {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}

You can find your app's link on the App Information page.

If you want to open in app store use

 let appstoreUrl =  "https://itunes.apple.com/in/app/myapp-test/id11111111?mt=8"
UIApplication.shared.openURL(URL(string: appstoreUrl)!)

if you want in itune store use

  let ituneUrl =  "itms-apps://itunes.apple.com/in/app/myapp-test/id11111111?mt=8"
UIApplication.shared.openURL(URL(string: ituneUrl)!)

In Swift 4.2 and Xcode 10.2

You have two ways to open App Store or iTunes Store

If you want to open App Store use https or if you want to open iTunes Store use itms

Ex: https://itunes.apple.com/in/app/yourAppName/id14****4?mt=8 //For App Store

itms://itunes.apple.com/in/app/yourAppName/id14****4?mt=8 //For iTunes Store

Method 1: This is simple direct and old approach

let url  = NSURL(string: "https://itunes.apple.com/in/app/smsdaddy/id1450172544?mt=8")//itms   https
if UIApplication.shared.canOpenURL(url! as URL) {
UIApplication.shared.openURL(url! as URL)
}

Method 2: New approach

if let url = URL(string: "https://itunes.apple.com/in/app/smsdaddy/id1450172544?ls=1&mt=8") {
if #available(iOS 10.0, *) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
// Earlier versions
if UIApplication.shared.canOpenURL(url as URL) {
UIApplication.shared.openURL(url as URL)
}
}
}

Swift 5

let url = "your app url"
if #available(iOS 10.0, *) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
else {
// Earlier versions
if UIApplication.shared.canOpenURL(url as URL) {
UIApplication.shared.openURL(url as URL)
}

For Swift 5 (tested code) to open App Store link

if let url = URL(string: "https://itunes.apple.com/in/app/your-appName/id123456?mt=8")
{
if #available(iOS 10.0, *) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
else {
if UIApplication.shared.canOpenURL(url as URL) {
UIApplication.shared.openURL(url as URL)
}

For those looking for the updated working solution

Most of the given solutions here are outdated & deprecated, like "canOpenURL", "openURL" etc.

let appStoreLink = "https://apps.apple.com/app/{app-name}/{app-id}"


guard let url = URL(string: appStoreLink) else { return }
UIApplication.shared.open(url)
