In a device detection, what would be the user agent for the new iPhone 8, iPhone 8 Plus and iPhone X?
回答1:
Here is the user agent string for them:
Mozilla/5.0 (iPhone; CPU OS 11_0 like Mac OS X) AppleWebKit/604.1.25 (KHTML, like Gecko) Version/11.0 Mobile/15A372 Safari/604.1

The iOS 11 GM firmware model number is 15A372, which will very likely be the same as the model number of the final iOS 11.
Here is a user agent from a beta version of iOS 11, which has the AppleWebKit and Safari version number.

As far as I know, user agent for iPhone 8, iPhone 8 plus and iPhone X are same. To detect device we need to check screen size of the device.
iPhone 8 - (750px x 1334px)
Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Mobile/15A372 Safari/604.1
iPhone 8 Plus - (1242px x 2208px)
Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Mobile/15A372 Safari/604.1
iPhone X - (1125px x 2436px)
Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Mobile/15A372 Safari/604.1
