1.我通過appstore下載了舊的ipa文件。先安裝壹個PP助手。把妳的手機和電腦連接起來！
在itunes界面中點擊數據庫；
/iknow-pic . cdn . BCE Bos . com/242 DD 42 a 2834349 bcea 22188 C4 ea 15 ce 36 D3 be 13 " target = " _ blank " title = " " class = " ikqb _ img _ alink " >中。/iknow-pic . cdn .

2.在數據庫中找到之前下載的ipa文件，如下圖所示，點擊鼠標右鍵，在資源管理器中顯示；

3.找到下載的ipa文件，鼠標右鍵選擇用PP助手安裝；

4.PP助手啟動，檢測手機連接！開始連接手機；
/iknow-pic . cdn . BCE Bos . com/d 62 a 6059252 DD 42 AE 3 ad 4 ea 60 E3 b5 bb 5c 9 eab 813 " target = " _ blank " title = " " class = " ikqb _ img _ alink " & gt；/iknow-pic . cdn .

擴展數據:
Ipa文件本質上是壹個zip壓縮包(不是rar或7z包)，它包含三個組件。有效載荷目錄下的app目錄，是軟件的主程序；ITunesArtwork本質上是壹個不帶後綴的png圖片，用於在iTunes中顯示圖標。ITunesMetadata.plist記錄買家信息、售價等數據。
