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]];

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。

根据苹果公司的最新文件 你需要使用

appStoreLink = "https://itunes.apple.com/us/app/apple-store/id375380948?mt=8"  

或

SKStoreProductViewController 

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]];

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];

至少iOS 9及以上版本

直接在App Store打开

一个应用程序

itms-apps://itunes.apple.com/app/[appName]/[appID]
