如果你有应用商店id，你最好使用它。特别是当您将来可能更改应用程序的名称时。

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

如果你没有应用商店id，你可以根据这个文档创建一个url https://developer.apple.com/library/ios/qa/qa1633/_index.html

+ (NSURL *)appStoreURL
{
    static NSURL *appStoreURL;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        appStoreURL = [self appStoreURLFromBundleName:[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleName"]];
    });
    return appStoreURL;
}

+ (NSURL *)appStoreURLFromBundleName:(NSString *)bundleName
{
    NSURL *appStoreURL = [NSURL URLWithString:[NSString stringWithFormat:@"itms-apps://itunes.com/app/%@", [self sanitizeAppStoreResourceSpecifier:bundleName]]];
    return appStoreURL;
}

+ (NSString *)sanitizeAppStoreResourceSpecifier:(NSString *)resourceSpecifier
{
    /*

     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.
     */
    resourceSpecifier = [resourceSpecifier stringByReplacingOccurrencesOfString:@"&" withString:@"and"];
    resourceSpecifier = [[NSString alloc] initWithData:[resourceSpecifier dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES] encoding:NSASCIIStringEncoding];
    resourceSpecifier = [resourceSpecifier stringByReplacingOccurrencesOfString:@"[!¡\"#$%'()*+,-./:;<=>¿?@\\[\\]\\^_`{|}~\\s\\t\\n]" withString:@"" options:NSRegularExpressionSearch range:NSMakeRange(0, resourceSpecifier.length)];
    resourceSpecifier = [resourceSpecifier lowercaseString];
    return resourceSpecifier;
}

通过测试

- (void)testAppStoreURLFromBundleName
{
    STAssertEqualObjects([AGApplicationHelper appStoreURLFromBundleName:@"Nuclear™"].absoluteString, @"itms-apps://itunes.com/app/nuclear", nil);
    STAssertEqualObjects([AGApplicationHelper appStoreURLFromBundleName:@"Magazine+"].absoluteString, @"itms-apps://itunes.com/app/magazine", nil);
    STAssertEqualObjects([AGApplicationHelper appStoreURLFromBundleName:@"Karl & CO"].absoluteString, @"itms-apps://itunes.com/app/karlandco", nil);
    STAssertEqualObjects([AGApplicationHelper appStoreURLFromBundleName:@"[Fluppy fuck]"].absoluteString, @"itms-apps://itunes.com/app/fluppyfuck", nil);
    STAssertEqualObjects([AGApplicationHelper appStoreURLFromBundleName:@"Pollos Hérmanos"].absoluteString, @"itms-apps://itunes.com/app/polloshermanos", nil);
    STAssertEqualObjects([AGApplicationHelper appStoreURLFromBundleName:@"Niños and niñas"].absoluteString, @"itms-apps://itunes.com/app/ninosandninas", nil);
    STAssertEqualObjects([AGApplicationHelper appStoreURLFromBundleName:@"Trond, MobizMag"].absoluteString, @"itms-apps://itunes.com/app/trondmobizmag", nil);
    STAssertEqualObjects([AGApplicationHelper appStoreURLFromBundleName:@"!__SPECIAL-PLIZES__!"].absoluteString, @"itms-apps://itunes.com/app/specialplizes", nil);
}

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，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)!)
    }

直接链接:没有重定向而有直接链接:

使用苹果服务营销工具:https://tools.applemediaservices.com/获得真正的直接链接 将https://替换为itms-apps:// 用UIApplication.shared打开链接。打开(url，选项:[:])

注意，这些链接只在实际设备上工作，而不是在模拟器中。

来源:

评论:新的链接归功于@rwcorbett 苹果文档:https://developer.apple.com/library/ios/#qa/qa2008/qa1629.html

我认为苹果已经为应用程序链接提供了一个新的链接: https://apps.apple.com/app/id1445530088或https://apps.apple.com/app/ {your_app_id}

这是工作和直接链接在ios5

NSString *iTunesLink = @"http://itunes.apple.com/app/baseball-stats-tracker-touch/id490256272?mt=8";  
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink]];
