Iphone long cannot recognize by QR code. iphone long cannot recognize

Long-pressed QR codes on Android can be recognized (provided that your version supports this function), but it cannot be recognized by the Apple version. It was detected by a personal test that the scaling problem was:

1. Set the initial scaling to 1. The maximum scaling value must be greater than or equal to 1. scaling is not supported. ---> Identifiable.

For example, <meta content = "width = device-width, initial-scale = 1, maximum-scale = 1.2, user-scalable = 0" name = "viewport"/>

2. Set the initial scaling to be smaller than 1 or greater than 1. The maximum scaling value is greater than or equal to the initial scaling. scaling is not supported. ---> Cannot be recognized.

For example, <meta content = "width = device-width, initial-scale = 1.1, maximum-scale = 1.2, user-scalable = 0" name = "viewport"/>

 

3. Set the initial scaling to 1. The maximum scaling value must be greater than or equal to 1. scaling is supported. ---> The page can be identified before it is scaled. Once the page is scaled, it cannot be identified.

For example, <meta content = "width = device-width, initial-scale = 1, maximum-scale = 1.2, user-scalable = 1" name = "viewport"/>

4. Do not set ----> it cannot be identified.

5. The page has a css style fixed ---> which cannot be identified.

 

I don't know if this is an apple issue or a problem. To be compatible, you can only set the initial scaling to 1 and the maximum scaling value to be greater than or equal to 1. scaling is not supported.
