1. Import with iTunes. First, connect the iPhone to your computer and open iTunes. In iTunes, locate and click your device icon. Then, select the Book option in the left panel and click Book in File * * *. Next, you can drag the TXT novel file directly into the "Books" area of iTunes, or click "Add File" to select the file you want to import. After making your selection, click the Synchronize button to start the synchronization process.

2. Import with iBooks. If the iBooks application is already installed on your iPhone, you can directly drag and drop the TXT novel file into the iBooks application. You can also buy and download books through the iBooksStore.

3. Use a third-party application (such as Calibre) to import. Calibre is a popular e-book conversion and management tool, which can help you convert TXT files into formats supported by AppleBooks, such as ePub or PDF. After using Calibre, you can drag and drop the converted file directly into the Book application on the iPhone.

4. Use every drop to send the import. If both your Mac and iPhone support Wi-Fi and Bluetooth, and airdrop is set to "Everyone", you can use airdrop to transfer TXT novel files directly from your Mac to your iPhone.
