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。

在SwiftUI - IOS 15.0

//
//  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()
    }
}

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)

这里的大多数解决方案都过时了

为那些寻找更新的工作解决方案

// 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)
