ipad iphone開發_如何釋放iPhone或iPad的消息應用程序佔用的空間
ipad iphone開發
If you send and receive a lot of text messages, the Messages app can take up a significant of space on your iPhone or iPad. Not only does it store your text message history, but it also keeps photo and video attachments you’ve received. Here’s how to free up that space if you’re running low.
如果您發送和接收大量文本消息，則「消息」應用程序可能會佔用iPhone或iPad上的大量空間。 它不僅存儲您的短信歷史記錄，而且還保留您收到的照片和視頻附件。 如果電量不足，請按以下方法釋放空間。
查看消息應用程序正在使用多少空間 (See How Much Space the Messages App is Using)
You can check how much space the Messages app is using on your device from the Storage screen. Open the Settings app on your iPhone or iPad and navigate to General > iPhone Storage (or iPad Storage) and wait for everything to load (it may take around 20 seconds or so).
您可以從「存儲」屏幕檢查Messages應用程序在設備上使用了多少空間。 在iPhone或iPad上打開「設置」應用，然後導航至「常規」>「 iPhone存儲(或iPad存儲)」，然後等待所有內容加載(可能需要20秒鐘左右)。
Next, scroll down the list and look for the Messages app. You’ll see how much storage space it’s using up. In my case, it’s taking up 1.14 GB. If yours is taking up a significant amount of space, read on to learn how you can free it up.
接下來，向下滾動列表並查找「消息」應用程序。 您會看到它正在消耗多少存儲空間。 就我而言，它佔用了1.14 GB。 如果您要佔用大量空間，請繼續閱讀以瞭解如何釋放空間。
自動刪除舊郵件 (Automatically Delete Old Messages)
To prevent messages from building up forever and taking up a larger and larger amount of storage space, you can set all messages to delete themselves after a certain period of time.
爲了防止消息永久堆積並佔用越來越大的存儲空間，可以將所有消息設置爲在一定時間後刪除自己。
Bear in mind, though, that any messages that do get deleted will be gone forever. So if you want to keep a record of your messages or keep certain messages forever, you probably won’t want to have them deleted automatically. To change this setting, open up the Settings app and tap on 「Messages.」
但是請記住，任何確實刪除的消息將永遠消失。 因此，如果您想保留一條消息記錄或永久保留某些消息，則可能不想自動刪除它們。 要更改此設置，請打開「設置」應用程序，然後點擊「消息」。
Scroll down and tap on 「Keep Messages」.
向下滾動並點擊「保留消息」。
Choose an expiration period. By default, your iPhone or iPad will keep messages 「Forever」, but you can choose to keep them for 「30 Days」 or 「1 Year」 if you prefer.
選擇一個有效期。 默認情況下，您的iPhone或iPad會將消息「永久保存」，但您可以根據需要選擇將其保留「 30天」或「 1年」。
As for audio messages, your device will automatically delete them two minutes after you listen to them. This prevents them from taking up space forever even after you’re completely done with them. To change this, though, you can go back to the main Messages screen in the settings and tap on 「Expire」 under 「Audio Messages」.
對於音頻消息，您的設備會在聽完語音後兩分鐘自動將其刪除。 即使您完全用完它們，這也可以防止它們永遠佔用空間。 但是，要更改此設置，您可以返回設置中的主消息屏幕，然後點擊「音頻消息」下的「過期」。
From there, you can choose to have them automatically deleted after two minutes or never have them deleted (unless you delete them manually).
從那裏，您可以選擇讓它們在兩分鐘後自動刪除，或者從不刪除(除非您手動刪除它們)。
批量刪除照片，視頻和附件 (Bulk Delete Photos, Videos, and Attachments)
You might be familiar with one way to delete messages and attachments in the Messages app, which is by long-pressing on a message or photo, tapping 「More」, selecting what you want to delete, and tapping the trash can. But this is the slowest way to do it, and you’ll have to hunt through your conversations to find all those images that you want to delete.
您可能熟悉一種在「消息」應用程序中刪除消息和附件的方法，該方法是長按消息或照片，點擊「更多」，選擇要刪除的內容，然後點擊垃圾桶。 但這是最慢的方法，您必須在對話中搜尋以找到所有要刪除的圖像。
You can also tap on the round 「i」 button in the top-right corner of a conversation to view all of that conversations attachments, and then delete any media you no longer need. However, this still isn’t the best way to go.
您也可以點擊對話右上角的圓形「 i」按鈕以查看所有對話附件，然後刪除不再需要的任何媒體。 但是，這仍然不是最好的方法。
Instead, go back into the Settings app and navigate to General > iPhone Storage (or iPad Storage) like you did before. Scroll down the list and select the Messages app. From there, tap on 「Review Large Attachments」.
相反，像以前一樣，回到「設置」應用並導航至「常規」>「 iPhone存儲」(或iPad存儲)。 向下滾動列表，然後選擇「消息」應用。 從那裏，點擊「查看大型附件」。
This will provide you a list of every single photo, video, and other attachment that the Messages app has saved from all of your conversation threads, and it’s in order by largest size first.
這將爲您提供Messages應用程序已從所有對話線程中保存的每張照片，視頻和其他附件的列表，並且按照最大大小的順序排列。
To delete one, simply just swipe to the left and hit 「Delete」.
要刪除一個，只需向左滑動並點擊「刪除」即可。
Unfortunately, there’s no 「Select All」 option or even a way to select multiple attachments and delete them in one swoop. However, this is still the best way to get rid of the largest attachments with minimal effort.
不幸的是，沒有「全選」選項，甚至沒有一種選擇多個附件並一舉刪除它們的方法。 但是，這仍然是用最少的努力擺脫最大的附件的最佳方法。
If you want to organize this list into specific media types, go back a screen and below 「Review Large Attachments」 you’ll see 「Documents & Data」 followed by a list of the different kinds of media.
如果要將此列表組織爲特定的媒體類型，請返回屏幕，然後在「查看大型附件」下方看到「文檔和數據」，然後是各種媒體的列表。
Tapping on one will only show attachments of that kind. So if you tap on 「Photos」, it will only show photos.
輕按一個只會顯示此類附件。 因此，如果您點擊「照片」，它將僅顯示照片。
If you want to save a photo or video before you delete it for good, you can tap on it and then select the Share button in the top-left corner.
如果要保存照片或視頻，然後再將其永久刪除，則可以點擊它，然後選擇左上角的「共享」按鈕。
From there, you can AirDrop it to another device, send it in an email, save it to a cloud storage service, and more.
從那裏，您可以將其空投到另一臺設備，通過電子郵件發送，將其保存到雲存儲服務等。
刪除整個對話主題 (Delete Entire Conversation Threads)
If Messages is using a lot of space, image attachments are likely to blame, so simply deleting text conversations may not help enough. However, if you have long conversations full of text messages, they might take up quite a bit more space than you think. You can delete them and free up that space, assuming you don’t want to keep those conversations.
如果郵件佔用大量空間，則可能是圖片附件受到了指責，因此僅刪除文本對話可能並不能提供足夠的幫助。 但是，如果您在長時間的對話中充斥着短信，則它們可能會佔用比您想象的要大得多的空間。 如果您不想保留這些對話，則可以刪除它們並釋放該空間。
You can delete an entire conversation thread in the Messages app by swiping left on it and tapping 「Delete」. This will delete all messages in the thread, as well as all media attachments.
您可以通過在消息應用中向左滑動並點擊「刪除」來刪除整個對話線程。 這將刪除線程中的所有消息以及所有媒體附件。
To bulk-delete multiple conversation threads at once, tap the 「Edit」 button on the main Messages screen and select multiple conversations. Tap 「Delete」 in the bottom-right corner of the screen to delete them.
要一次批量刪除多個對話線程，請在「消息」主屏幕上點擊「編輯」按鈕，然後選擇多個對話。 點擊屏幕右下角的「刪除」將其刪除。
Text messages alone don’t really use up that much space. However, if you’ve racked up several years of photos and videos that you’ve sent and received, it’s likely that you’re in need of a messaging audit anyway.
僅文本消息並不會真正佔用那麼多空間。 但是，如果您已經累積了幾年來發送和接收的照片和視頻，則很可能仍然需要進行郵件審覈。
