Check if iOS version is 3.0 or higher with PHP or Javascript

Question

I need to check if an iOS device visiting my Website has iOS 3.0 or higher installed. Can I do that?

Answer 1

Bit of an older question, but I believe none of the answers currently given answer the question appropriately.

If you want to do something like

if(iOS_version > 3){
    // Open something
}

Then I believe you are looking for

if(/(iPhone|iPad|iPod)\sOS\s3/.test(navigator.userAgent)) {
    // use apple maps
}

Where s3 is looking for iOS3. Change s3 to s9 to check for iOS9
