尽管这里有很多答案，但是似乎没有任何一种链接到开发者应用的建议还能够正常工作。我最近访问时，曾使用以下格式使之运作起来：

itms-apps://itunes.apple.com/developer/developer-name/id123456789

这个方法已经不再适用，但是删除开发者名称可以解决问题：

itms-apps://itunes.apple.com/developer/id123456789

至少需要iOS 9及以上版本

• 可以直接在App Store中打开

一款应用程序

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

开发人员应用程序列表

itms-apps://itunes.apple.com/developer/[developerName]/[developerID]

这里的大部分解决方案都已经过时和废弃了。
对于那些寻找最新可行解决方案的人。

// let appStoreLink = "https://apps.apple.com/app/{app-name}/{app-id}"

guard let url = URL(string: Constants.App.appStoreLink) else { return }
UIApplication.shared.open(url)

如果您有应用商店ID，最好使用它，尤其是将来可能更改应用程序名称的情况下。

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

如果您没有应用程序商店ID，可以根据此文档创建一个基于URL的链接：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
{
    /*
     https://developer.apple.com/library/ios/qa/qa1633/_index.html
     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;
}

通过了这个测试

- (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);
}

它将直接打开App Store。

NSString *iTunesLink = @"itms-apps://itunes.apple.com/app/ebl- 
skybanking/id1171655193?mt=8";

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink]];

在SwiftUI - IOS 15.0中

//
//  Test.swift
//  PharmaCodex
//

import SwiftUI

struct Test: View {
    
    var body: some View {
        
        VStack {
            
            Button(action: {
                guard let writeReviewURL = URL(string: "https://apps.apple.com/app/id1629135515?action=write-review") else {
                    fatalError("Expected a valid URL")
                }
                UIApplication.shared.open(writeReviewURL, options: [:], completionHandler: nil)
                
            }) {
                Text("Rate/Review")
            }
            
            
        }
    }
}

struct Test_Previews: PreviewProvider {
    static var previews: some View {
        Test()
    }
}

尝试这种方式

http://itunes.apple.com/lookup?id="在此处输入您的应用程序ID"返回json。从中找到键“trackViewUrl”，其值是所需的URL。使用此URL（只需将https://替换为itms-apps://）。这很有效。

例如，如果您的应用程序ID是xyz，则转到此链接http://itunes.apple.com/lookup?id=xyz

然后找到键“trackViewUrl”的URL。这是您的应用程序在应用商店中的URL，要在Xcode中使用此URL，请尝试以下操作

NSString *iTunesLink = @"itms-apps://itunes.apple.com/us/app/Your app name/id Your app ID?mt=8&uo=4";
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink]];

谢谢
