这对我来说非常有效，只使用APP ID:

 NSString *urlString = [NSString stringWithFormat:@"http://itunes.apple.com/app/id%@",YOUR_APP_ID];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];

重定向的数量为0。

这是重定向/链接应用商店中其他现有应用程序的简单而简短的方法。

 NSString *customURL = @"http://itunes.apple.com/app/id951386316";

 if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:customURL]])
 {
       [[UIApplication sharedApplication] openURL:[NSURL URLWithString:customURL]];
 } 

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);
}

许多答案建议使用“itms”或“itms-apps”，但苹果并没有特别推荐这种做法。他们只提供以下方式打开App Store:

清单1从iOS应用程序启动App Store

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

参见https://developer.apple.com/library/ios/qa/qa1629/_index.html, 2014年3月更新。

对于支持iOS 6及以上版本的应用程序，苹果提供了一种应用内机制来呈现应用程序商店:SKStoreProductViewController

- (void)loadProductWithParameters:(NSDictionary *)parameters completionBlock:(void (^)(BOOL result, NSError *error))block;

// Example:
SKStoreProductViewController* spvc = [[SKStoreProductViewController alloc] init];
spvc.delegate = self;
[spvc loadProductWithParameters:@{ SKStoreProductParameterITunesItemIdentifier : @(364709193) } completionBlock:^(BOOL result, NSError *error){ 
    if (error)
        // Show sorry
    else
        // Present spvc
}];

注意，在iOS6上，如果有错误，completion块可能不会被调用。这似乎是一个在iOS 7中解决的错误。

苹果刚刚公布了appstore.com的网址。

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

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

对于Xcode 9.1和Swift 4:

进口StoreKit:

进口StoreKit

2.遵守协议

SKStoreProductViewControllerDelegate

3.实现协议

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)
        }
    }   
}

3.1

func productViewControllerDidFinish(_ viewController: SKStoreProductViewController) {
    viewController.dismiss(animated: true, completion: nil)
}

使用方法:

openStoreProductWithiTunesItemIdentifier(标识符:“here_put_your_App_id”)

注意:

输入你的APP的确切ID是非常重要的。因为这会导致错误(不显示错误日志，但没有任何工作正常，因为这个)
