Step 1: Select the icon to change.
First, you need to select the icon you want to change. On the desktop of Apple's mobile phone, press and hold the application icon that needs to be changed until all the icons start to shake.
Step 2: Select a new icon.
When the icon starts to shake, you can click the icon that needs to be replaced, and then select the "Replace application icon" option. In the pop-up interface, you can choose the icon provided by Apple, or you can choose your own picture from the album as the application icon.
Step 3: Adjust the icon position
When you have changed all the icons that need to be changed, you can adjust the position of the icon by long-pressing and dragging the icon. You can also change the position of the icon on the bottom "docking bar".
Through the above three steps, you can easily set the desktop icon of Apple mobile phone. If you want to restore the default icon, just press and hold the icon you want to change, and then select "Restore Default Icon".
