Open the Tik Tok app on your mobile phone, click "Clean up the occupied space" under the settings, and choose to clear temporary files and source files. Below I will demonstrate the detailed operation steps:

(iPhone 12 mobile phone, iOS 14.6 system, Tik Tok 19.5.0)

1. First, on the page of Tik Tok's personal heart, click three horizontal icons.

2. Then in the sidebar that opens, click Settings.

3. Then in the open settings page, click Clean up the occupied space.

4. Finally, in the opened page, click Clear behind the temporary file and the resource file respectively.

These are all the steps that iphone Tik Tok takes up too much memory. Come and try what you have learned ~
