If you want to screen record on TikTok, there are a few different methods you can use. One is to use the native screen recording function in your device's operating system. For example, on an iPhone, you can go to Settings > Control Center > Customize Controls, then add Screen Recording to your Control Center. Once you've done that, you can simply swipe up from the bottom of your screen to access the Control Center and tap the Screen Recording button.
Another method is to use a third-party screen recording app such as QuickTime Player or Reflector 2. These apps will let you record your screen activity as well as any audio that accompanies it. To use either of these apps, simply launch them and then start recording by hitting the respective Record button. Once you're done recording, just hit Stop and then save your recordings as desired.
And that's all there is to it! Whether you use the built-in screen recording function on your device or opt for a third-party app,screen recording on TikTok is easy peasy.
