Unfortunately, directly setting a YouTube song as a ringtone on an iPhone is not possible due to copyright restrictions and limitations of the iOS operating system. However, you can still achieve this by following these steps:
- First, you need to download the YouTube song to your computer. There are various online YouTube-to-MP3 converters available that can help you with this.
- Once you have the MP3 file of the song, you can transfer it to your iPhone using iTunes or the Apple Music app on your computer.
- Connect your iPhone to your computer using a USB cable.
- Open iTunes or the Apple Music app and select your device.
- Go to the "File Sharing" or "Music" section and drag the MP3 file into the app.
- Sync your iPhone with iTunes or the Apple Music app to transfer the song to your device.
- On your iPhone, go to "Settings" > "Sounds & Haptics" > "Ringtone" and select the song you transferred as your custom ringtone.
