Your old iPad might be still going strong, but ifall yourapps need newer versions of iOS to run, it feels like you can’t do anything with it. Don’t worry, we’re here with a clever trick that will help you load up your old device with older versions of of your favorite apps.

您的舊iPad可能仍會很強大，但是如果您所有的應用都需要執行較新版本的iOS，則感覺您無能為力。 不用擔心，我們在這裡提供了一個巧妙的技巧，可以幫助您使用舊版本的您喜歡的應用程式載入舊裝置。

iOS的舊版本和新應用程式有什麼關係？ (What’s the Deal With Old Versions of iOS and New Apps?)

As of the publication of this article, we’re currently on iOS 9 and, in a short few months, iOS 10 will roll out to the public. Although Apple does a pretty admirable job dragging old hardware along for each iOS update, every train has a final stop. The iPhone 4 is stuck at iOS 7.1.2, for example, and the first-gen iPad is stuck all the way back at iOS 5.1.1. With every new wave of iOS hardware, a little bit of the legacy hardware is left behind.

截至本文釋出時，我們目前正在使用iOS 9，並且在短短的幾個月內，iOS 10將向公眾推出。 儘管Apple在每次iOS更新中都將舊硬體拖到一起做得非常出色，但每列火車都有最後的一站。 例如，iPhone 4卡在iOS 7.1.2上，第一代iPad卡在iOS 5.1.1上。 隨著每一波新的iOS硬體浪潮，一小部分舊硬體都被拋在後面。

While getting stuck on older software is par for the course, it can be frustrating. Many people abandon these old-but-still-functioning devices not because they’re upset about missing out on the new iOS features, but because it’s such a pain to download apps to them.

雖然固守舊軟體固然可以解決問題，但令人沮喪。 許多人放棄了這些舊的但仍能正常執行的裝置，並不是因為他們對錯過iOS的新功能而感到沮喪，而是因為將應用程式下載到其中很痛苦。

The way Apple has the App Store configured, you are always directed towards the newest version of anapplication. On the surface, this is a perfectly sensible thing for Apple to do: why would they ever want you to download older, buggier, and potentially less securesoftware when there’s an updated version available? When you’re on an older device, however, this means an app may not be compatible with your old version of iOS. Search for an application in the App Store on your iPad 1, for example, and the App Store app will tell you that the app can’t be downloaded because it requires a device running iOS 7 (or 8, or 9), and therefore can’t be installed on your iPad…even if there was an iOS 5 version of the app at some point in the past.

蘋果公司配置App Store的方式始終將您引導到應用程式的最新版本。 從表面上看，這對Apple來說是一件非常明智的事情：為什麼他們會希望您在更新版本可用的情況下下載較舊的，錯誤的，安全性可能較低的軟體？ 但是，當您使用較舊的裝置時，這意味著某個應用程式可能與您的舊版iOS不相容。 例如，在iPad 1上的App Store中搜索一個應用程式，該App Store應用程式會告訴您該應用程式需要執行iOS 7(或8或9)的裝置，因此無法下載。無法安裝在iPad上……即使過去某個時候有該應用程式的iOS 5版本。

What theydon’t tell you, though, is that you can easily (no jailbreak required) and legally (no piracy required) download old versions of applications to your older iOS devices with a pretty simple trick.

不過，他們沒有告訴您的是，您可以輕鬆地(無需越獄)並且合法(無需盜版)將舊版本的應用程式下載到較舊的iOS裝置上，並且非常簡單。

Before we walk you through that trick there is one minor and obvious caveat: the trick only works on apps that once had versions compatible with your OS. You can’t download an iOS 5 version of a six month old app that never had a version compatible with iOS 5.

在向您介紹該技巧之前，有一個小而明顯的警告：該技巧僅適用於曾經與您的作業系統相容的應用程式。 您無法下載六個月之久的應用程式的iOS 5版本，該版本從未與iOS 5相容。

With that in mind, let’s take a look at how to stock up your aging iPad 1 with apps, frustration free.

考慮到這一點，讓我們看一下如何使用無憂無慮的應用程式來儲存老化的iPad 1。

如何將舊應用程式版本下載到舊裝置 (How to Download Old App Versions to Your Older Device)

As we noted above, if you fire up an old iPad using iOS 5 and try to download darn nearanything from the App Store, iOS 5 is so ancient that installation will almost certainly fail for 99% of apps (even if that app is old enough to have an ancient iOS 5-era version).

如上所述，如果您使用iOS 5啟動舊版iPad，並嘗試從App Store下載任何內容，那麼iOS 5的版本是如此之舊，幾乎可以肯定99％的應用程式安裝都會失敗(即使該應用程式是舊的)足以擁有一個古老的iOS 5時代版本)。

However, if you purchase/download the current version of the application–on either a newer iOS device (like your iPhone 6) or using the iTunes desktop software on your Windows or Mac–then the older version of the application will be accessible to your older device. Why? Because Apple’s policy is that if you purchased an app (this applies even to free “purchases”), that the app should be available to any device in your personal collection that requests to download it. Whenan old iOS 5 device requests a new app from your library (rather than from the iTunes Store), it’ll search for an old, compatible version and–if one exists–grab it.

但是，如果您購買/下載該應用程式的當前版本(在較新的iOS裝置(例如iPhone 6)上或在Windows或Mac上使用iTunes桌面軟體)，則您可以訪問較舊版本的應用程式較舊的裝置。 為什麼？ 因為Apple的政策是，如果您購買了某個應用程式(甚至適用於免費的“購買”)，則該應用程式應可用於您個人收藏中要求下載該應用程式的任何裝置。 當舊的iOS 5裝置從您的媒體庫(而不是從iTunes Store)中請求一個新應用時，它將搜尋一箇舊的相容版本，如果有，請抓住它。

We’ll demonstrate the trick with the popular comic book reading app Comic Zeal. If you attempt to download Comic Zeal an an old device (which is presently listed in the App Store as requiring iOS 8.2 or above), you’ll get an installation error like the one we highlighted above.

我們將通過流行的漫畫閱讀應用程式Comic Zeal演示這一技巧。 如果您嘗試將舊版的Comic Zeal下載到舊裝置(目前在App Store中列為需要iOS 8.2或更高版本)，則會收到類似於我們上面突出顯示的安裝錯誤。

To get Comic Zeal on our iPad, we need to make a quick stop at either our computer or another, newer, iOS device. Does it matter which you use? Only if you’re downloading an application that is iPad only–if you search for an iPad only app on your iPhone you won’t see it in the search results.

要在iPad上使用Comic Zeal，我們需要在我們的計算機或另一臺更新的iOS裝置上快速停止。 使用哪個有關係嗎？ 僅當您下載僅iPad的應用程式時-如果您在iPhone上搜索僅iPad的應用程式，則不會在搜尋結果中看到它。

For our example, we’ll use iTunes. Fire up the app and search in the search box for the name of your application. Select the app in the search results. Click the “Buy” or “Get” button, depending on whether the app is paid or free.

對於我們的示例，我們將使用iTunes。 啟動應用程式，然後在搜尋框中搜索應用程式的名稱。 在搜尋結果中選擇應用。 單擊“購買”或“獲取”按鈕，具體取決於該應用程式是付費還是免費。

Once you click the Get or Buy button, you don’t have to wait for the app to actually download to your computer (and we recommend you don’t, actually, as it will be a new version you can’t use anyway).

單擊“獲取”或“購買”按鈕後，您不必等待應用程式實際下載到計算機上(我們建議您實際上不要這樣做，因為它將是您永遠無法使用的新版本) 。

Having purchased the app, head over to your older iOS device and search for the exact app in the App Store or click on the “Purchased” icon in the lower navigation bar. When you locate the app, click the “Install” button.

購買了應用程式後，轉到舊的iOS裝置並在App Store中搜索確切的應用程式，或單擊下部導航欄中的“已購買”圖示。 找到應用程式後，單擊“安裝”按鈕。

After you click “Install”, you’ll see a popup like the one below indicating that there is an older version of the app available for download. Click “Download” the last compatible version.

單擊“安裝”後，您將看到類似以下的彈出視窗，表明有較舊版本的應用程式可供下載。 單擊“下載”最新的相容版本。

At this point, the app will install as expected and you can use it, albeit without the features present in the newer updates.

此時，該應用程式將按預期安裝，您可以使用它，儘管沒有更新中提供的功能。

It might not be the most convenient way to go about doing things, but this little workaround is a great way to breath life into old hardware.

這可能不是最方便的處理方法，但是這種小變通方法是讓舊硬體充滿生機的好方法。
