当支持多个操作系统和平台时，创建链接可能会成为一个复杂的问题。例如，在iOS 7上不支持WebObjects(其中一些)，你创建的一些链接会打开另一个国家的商店，然后用户的等等。

有一个叫做iLink的开源库可以帮助你。

There advantages of this library is that the links would be found and created at run time (the library would check the app ID and the OS it is running on and would figure out what link should be created). The best point in this is that you don't need to configure almost anything before using it so that is error free and would work always. That's great also if you have few targets on same project so you don't have to remember which app ID or link to use. This library also would prompt the user to upgrade the app if there is a new version on the store (this is built in and you turn this off by a simple flag) directly pointing to the upgrade page for the app if user agrees.

复制两个库文件到你的项目(iLink.h & iLink.m)。

在你的appDelegate.m上:

#import "iLink.h"

+ (void)initialize
{
    //configure iLink
    [iLink sharedInstance].globalPromptForUpdate = YES; // If you want iLink to prompt user to update when the app is old.
}

例如，在你想打开评级页面的地方，只需使用:

[[iLink sharedInstance] iLinkOpenAppPageInAppStoreWithAppleID: YOUR_PAID_APP_APPLE_ID]; // You should find YOUR_PAID_APP_APPLE_ID from iTunes Connect 

不要忘记在同一个文件中导入iLink.h。

这里有一个很好的整个库的文档还有一个iPhone和Mac的示例项目。

苹果刚刚公布了appstore.com的网址。

There are three types of App Store Short Links, in two forms, one for iOS apps, another for Mac Apps: Company Name iOS: http://appstore.com/ for example, http://appstore.com/apple Mac: http://appstore.com/mac/ for example, http://appstore.com/mac/apple App Name iOS: http://appstore.com/ for example, http://appstore.com/keynote Mac: http://appstore.com/mac/ for example, http://appstore.com/mac/keynote App by Company iOS: http://appstore.com// for example, http://appstore.com/apple/keynote Mac: http://appstore.com/mac// for example, http://appstore.com/mac/apple/keynote Most companies and apps have a canonical App Store Short Link. This canonical URL is created by changing or removing certain characters (many of which are illegal or have special meaning in a URL (for example, "&")). To create an App Store Short Link, apply the following rules to your company or app name: Remove all whitespace Convert all characters to lower-case Remove all copyright (©), trademark (™) and registered mark (®) symbols Replace ampersands ("&") with "and" Remove most punctuation (See Listing 2 for the set) Replace accented and other "decorated" characters (ü, å, etc.) with their elemental character (u, a, etc.) Leave all other characters as-is. Listing 2 Punctuation characters that must be removed. !¡"#$%'()*+,-./:;<=>¿?@[]^_`{|}~ Below are some examples to demonstrate the conversion that takes place. App Store Company Name examples Gameloft => http://appstore.com/gameloft Activision Publishing, Inc. => http://appstore.com/activisionpublishinginc Chen's Photography & Software => http://appstore.com/chensphotographyandsoftware App Name examples Ocarina => http://appstore.com/ocarina Where’s My Perry? => http://appstore.com/wheresmyperry Brain Challenge™ => http://appstore.com/brainchallenge

从ios6开始，SKStoreProductViewController类被引入。你可以在不离开你的应用程序的情况下链接一个应用程序。x和Objective-C在这里。

SKStoreProductViewController对象表示一个存储，该存储允许 用户可以从应用商店购买其他媒体。例如，你的应用程序 可能会显示商店以允许用户购买另一款应用。

来自苹果开发者的新闻和公告。

Drive Customers Directly to Your App on the App Store with iTunes Links With iTunes links you can provide your customers with an easy way to access your apps on the App Store directly from your website or marketing campaigns. Creating an iTunes link is simple and can be made to direct customers to either a single app, all your apps, or to a specific app with your company name specified. To send customers to a specific application: http://itunes.com/apps/appname To send customers to a list of apps you have on the App Store: http://itunes.com/apps/developername To send customers to a specific app with your company name included in the URL: http://itunes.com/apps/developername/appname

其他说明:

为了避免重定向，可以将http://替换为itms://或itms-apps://。

请注意，itms://会将用户发送到iTunes商店，itms-apps://会将用户发送到App store !

有关命名的信息，请参见Apple QA1633:

https://developer.apple.com/library/content/qa/qa1633/_index.html。

编辑(截至2015年1月):

Itunes.com/apps链接应更新为appstore.com/apps。见上文QA1633，已更新。新的QA1629建议从应用程序启动商店的步骤和代码:

在你的电脑上启动iTunes。 搜索要链接的项目。 在iTunes中右键单击或控制单击项目名称，然后从弹出菜单中选择“复制iTunes Store URL”。 在你的应用中，用复制的iTunes URL创建一个NSURL对象，然后将这个对象传递给UIApplication的openURL:方法来在App Store中打开你的项目。

示例代码:

NSString *iTunesLink = @"itms://itunes.apple.com/app/apple-store/id375380948?mt=8";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink]];

iOS10 +:

 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink] options:@{} completionHandler:nil];

斯威夫特4.2

   let urlStr = "itms-apps://itunes.apple.com/app/apple-store/id375380948?mt=8"
    if #available(iOS 10.0, *) {
        UIApplication.shared.open(URL(string: urlStr)!, options: [:], completionHandler: nil)
        
    } else {
        UIApplication.shared.openURL(URL(string: urlStr)!)
    }

所有的答案都过时了，不管用;使用下面的方法。

开发人员的所有应用: itms-apps: / / apps.apple.com/developer/developer-name/developerId

单一应用程序: itms-apps: / / itunes.apple.com/app/appId

如果你想直接在app Store中打开应用，你应该使用:

itms-apps: / /……

这样，它将直接打开设备中的App Store应用程序，而不是先去iTunes，然后只打开App Store(当只使用itms://)

编辑时间:2017年4月。 itms-apps://实际上在iOS10中再次工作。我测试过了。

编辑:2013年4月。 这在iOS5及以上版本中不再适用。只使用

https://itunes.apple.com/app/id378458261

也没有更多的重定向。

从ios6开始正确的方法是使用SKStoreProductViewController类。

斯威夫特5. x:

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

    let parameters = [ SKStoreProductParameterITunesItemIdentifier : identifier]
    storeViewController.loadProduct(withParameters: parameters) { [weak self] (loaded, error) -> Void in
        if loaded {
            // Parent class of self is UIViewContorller
            self?.present(storeViewController, animated: true, completion: nil)
        }
    }
}
private func productViewControllerDidFinish(viewController: SKStoreProductViewController) {
    viewController.dismiss(animated: true, completion: nil)
}
// Usage:
openStoreProductWithiTunesItemIdentifier("1234567")

斯威夫特3. x:

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

    let parameters = [ SKStoreProductParameterITunesItemIdentifier : identifier]
    storeViewController.loadProduct(withParameters: parameters) { [weak self] (loaded, error) -> Void in
        if loaded {
            // Parent class of self is UIViewContorller
            self?.present(storeViewController, animated: true, completion: nil)
        }
    }
}

func productViewControllerDidFinish(_ viewController: SKStoreProductViewController) {
    viewController.dismiss(animated: true, completion: nil)
}
// Usage:
openStoreProductWithiTunesItemIdentifier(identifier: "13432")

你可以像这样获得应用的itunes项目标识符(而不是一个静态标识符):

斯威夫特3.2

var appID: String = infoDictionary["CFBundleIdentifier"]
var url = URL(string: "http://itunes.apple.com/lookup?bundleId=\(appID)")
var data = Data(contentsOf: url!)
var lookup = try? JSONSerialization.jsonObject(with: data!, options: []) as? [AnyHashable: Any]
var appITunesItemIdentifier = lookup["results"][0]["trackId"] as? String
openStoreProductViewController(withITunesItemIdentifier: Int(appITunesItemIdentifier!) ?? 0)

斯威夫特2. x:

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)
}
// Usage
openStoreProductWithiTunesItemIdentifier("2321354")

objective - c:

static NSInteger const kAppITunesItemIdentifier = 324684580;
[self openStoreProductViewControllerWithITunesItemIdentifier:kAppITunesItemIdentifier];

- (void)openStoreProductViewControllerWithITunesItemIdentifier:(NSInteger)iTunesItemIdentifier {
    SKStoreProductViewController *storeViewController = [[SKStoreProductViewController alloc] init];

    storeViewController.delegate = self;

    NSNumber *identifier = [NSNumber numberWithInteger:iTunesItemIdentifier];

    NSDictionary *parameters = @{ SKStoreProductParameterITunesItemIdentifier:identifier };
    UIViewController *viewController = self.window.rootViewController;
    [storeViewController loadProductWithParameters:parameters
                                   completionBlock:^(BOOL result, NSError *error) {
                                       if (result)
                                           [viewController presentViewController:storeViewController
                                                              animated:YES
                                                            completion:nil];
                                       else NSLog(@"SKStoreProductViewController: %@", error);
                                   }];

    [storeViewController release];
}

#pragma mark - SKStoreProductViewControllerDelegate

- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController {
    [viewController dismissViewControllerAnimated:YES completion:nil];
}

你可以像这样获得kAppITunesItemIdentifier(应用的itunes项目标识符):(而不是一个静态的)

NSDictionary* infoDictionary = [[NSBundle mainBundle] infoDictionary];
    NSString* appID = infoDictionary[@"CFBundleIdentifier"];
    NSURL* url = [NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/lookup?bundleId=%@", appID]];
    NSData* data = [NSData dataWithContentsOfURL:url];
    NSDictionary* lookup = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
    NSString * appITunesItemIdentifier =  lookup[@"results"][0][@"trackId"]; 
    [self openStoreProductViewControllerWithITunesItemIdentifier:[appITunesItemIdentifier intValue]];
