如何通过云存储实现iOS端App的扫码安装
需求背景
之前有人咨询，如何通过AppGallery Connect的SDK，实现一个完整的App安装的功能。之前的帖子有描述过主要步骤，但对于不了解AGC的用户，操作起来有点左支右绌。这篇帖子将结合AGC平台的操作，补充介绍实现方法。
由于AppLinking云侧增加了“允许网址清单”设置，清单里不支持URI Scheme格式，因此就不能通过AppLinking进行分享安装链接了。但我们通过原生方法将安装链接转成二维码，还是可以方便的进行扫码安装的。
集成步骤
1、在AppGallery Connect页面创建项目和应用，开通认证服务和云存储服务。开通后，将agconnect-services.plist加入到工程中。
2、在认证服务云侧页面，启用匿名帐号。
3、云存储的云侧，新增installer文件夹，打开文件夹，上传打好的ipa包。
4、在工程中，如下编辑Podfile文件。
target 'AGC-Installer' do
use_frameworks!
pod 'AGConnectAuth'
pod 'AGConnectStorage'
end
5、在AppDelegate里初始化AGCInstance实例。
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
AGCInstance.startUp()
return true
}6、如下示例代码编辑InstallerManager.swift文件。
import UIKit
import AGConnectStorage
let installerDir = "installer/"
let storage: AGCStorage = AGCStorage.getInstanceForBucketName("mystorage-awfpi")
let documentPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first! as NSString
let infoDictionary = Bundle.main.infoDictionary!
let bundleName = infoDictionary["CFBundleName"] as! String
let bundleVersion = infoDictionary["CFBundleShortVersionString"] as! String
class InstallerManager: NSObject {
func ipaDownloadUrl(ipaUrlBlock: @escaping (String) -> Void) {
let storageReference = storage.reference(withPath: installerDir + bundleName + ".ipa")
storageReference.getDownloadUrl().onSuccess(callback: { (url) in
ipaUrlBlock(url!.absoluteString!)
}).onFailure(callback: { (error) in
})
}
func writeToPlist(writeBlock: @escaping (Bool) -> Void) {
self.ipaDownloadUrl { (str) in
print(str)
let urlItem = NSMutableDictionary()
urlItem.setValue("software-package", forKey: "kind")
urlItem.setValue(str, forKey: "url")
let assets = NSArray(object: urlItem)
let metadata = NSMutableDictionary()
metadata.setValue(Bundle.main.bundleIdentifier, forKey: "bundle-identifier")
metadata.setValue(bundleVersion, forKey: "bundle-version")
metadata.setValue("software", forKey: "kind")
metadata.setValue(bundleName, forKey: "subtitle")
metadata.setValue(bundleName, forKey: "title")
let item0 = NSMutableDictionary()
item0.setValue(assets, forKey: "assets")
item0.setValue(metadata, forKey: "metadata")
let items = NSArray(object: item0)
let plist = NSMutableDictionary()
plist.setValue(items, forKey: "items")
let path = documentPath.appendingPathComponent("App.plist")
let result = plist.write(toFile: path, atomically: true)
writeBlock(result)
}
}
func uploadPlist(uploadPlistBlock: @escaping (AGCStorageReference) -> Void) {
let storageReference = storage.reference(withPath: installerDir + "App.plist")
let task = storageReference.uploadFile(URL(fileURLWithPath: documentPath.appendingPathComponent("App.plist")))
task?.onSuccess(callback: { (result) in
print("upload success")
uploadPlistBlock(storageReference)
}).onFailure(callback: { (error) in
print("upload faile")
})
}
func installerUrl(installerUrlBlock: @escaping (String) -> Void) {
self.writeToPlist { (writed) in
if writed {
self.uploadPlist { (storageReference) in
storageReference.getDownloadUrl().onSuccess(callback: { (url) in
let urlStr = url!.absoluteString! as NSString
let customAllowedSet = NSCharacterSet(charactersIn: "!*'();:@&=+$,/?%#[]").inverted
let encodeurl = urlStr.addingPercentEncoding(withAllowedCharacters: customAllowedSet)
let downloadUrl = "itms-services:///?action=download-manifest&url=" + encodeurl!
installerUrlBlock(downloadUrl)
}).onFailure(callback: { (error) in
assert(false, "can not get ipa installer url")
})
}
}
}
}
}7、如下编辑ViewController.swift文件。
8、如上述步骤，先生成安装链接，再将链接生成二维码，即可实现App的扫码安装功能。
总结
通过InstallerManager产生的链接即安装链接，如果您不想通过扫码安装的方式来安装应用，可自行选择其他方式来安装。
