iOS Development - Implementing a QR Code Scanning Interface

Implementation of a Payment Interface Similar to the One Below#

Interface Analysis#

  1. Black semi-transparent background
  2. The green headerView below the navigationBar
  3. Implementation of the scanning box and the green dynamic scanning line
  4. Prompt text below the scanning box

The implementation of the black background may be different from what you imagine, as shown in the image below (1/2/3 in the image are just identifiers, not in order). First, you need to place a backView, then place the scanning box 3 in the middle, followed by the four 1s on the top, bottom, left, and right, and finally place the headerView and prompt text 2.
