iOS 通過UIImagePickerController選擇照片後，系統偷偷地執行了拷貝操作

偶然發現

在多次使用​

​UIImagePickerController​

​​進行照片選擇後

發現應用所占記憶體有50多M!!!

覺得不可思議

通過​

​Devices and Simulators ->選擇對應應用->齒輪圖示->Download Container​

​​下載下傳沙盒檔案

發現​​

​Tmp​

​​檔案夾内儲存了所有選擇過的照片

這就尴尬😓了

我就選個圖檔

你給我偷偷搞這麼多操作 😉

一個幹脆

我把​​

​Tmp​

​​删掉了

結果控制台給我抛出了一些​​

​警告​

​
