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。

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]];
 } 

这段代码生成iOS上的App Store链接

NSString *appName = [NSString stringWithString:[[[NSBundle mainBundle] infoDictionary]   objectForKey:@"CFBundleName"]];
NSURL *appStoreURL = [NSURL URLWithString:[NSString stringWithFormat:@"itms-apps://itunes.com/app/%@",[appName stringByReplacingOccurrencesOfString:@" " withString:@""]]];

在Mac上用http替换itms-apps:

NSURL *appStoreURL = [NSURL URLWithString:[NSString stringWithFormat:@"http:/itunes.com/app/%@",[appName stringByReplacingOccurrencesOfString:@" " withString:@""]]]; 

在iOS上打开URL:

[[UIApplication sharedApplication] openURL:appStoreURL];

Mac:

[[NSWorkspace sharedWorkspace] openURL:appStoreURL];

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]];

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。

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

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。
