How to detect iPhone 5 (widescreen devices)?

How to Detect iPhone 5 (widescreen devices) 📱

So, you've just upgraded to Xcode 4.5 GM and discovered that you can now apply the '4" Retina' size to your view controller in the storyboard. That's pretty exciting! 🎉

But now you're faced with a challenge - you want to create an application that runs on both iPhone 4 and iPhone 5. This means you need to build every window twice and also detect whether the user has an iPhone with a 3.5" or 4" screen, and then apply the appropriate view.

The Dilemma 🤔

How do you go about detecting whether the user has an iPhone with a widescreen (like the iPhone 5) or a regular screen (like the iPhone 4)?

Solution 1: Screen Size Detection 📏

One way to solve this problem is by detecting the screen size of the device. You can use the following method to get the screen size programmatically:

let screenSize = UIScreen.main.bounds.size

Now, you have the screen size in your hands (figuratively speaking, of course! 😄). You can compare it with the standard sizes of the iPhone 4 (3.5") and iPhone 5 (4") screens.

Here's an example of how you could implement this:

if screenSize.height == 480 {
    // iPhone 4 or earlier
    // Apply the view for the regular 3.5" screen
} else if screenSize.height == 568 {
    // iPhone 5 or later
    // Apply the view for the widescreen 4" screen
} else {
    // It's a different device
    // Handle the view accordingly
}

Solution 2: Trait Collection Size Classes 📐

Another way to approach this problem is by utilizing Trait Collection Size Classes, introduced in iOS 8. Size classes provide a way to adapt your interface based on the available space on the device's screen.

You can use size classes to differentiate between regular and compact height screens, which can help detect iPhone 5 or any other device with a widescreen.

Here's an example of how to use size classes for this purpose:

if self.traitCollection.verticalSizeClass == .compact {
    // Regular height screen
    // Apply the view for regular screens (e.g., iPhone 4)
} else {
    // Compact height screen
    // Apply the view for widescreen screens (e.g., iPhone 5)
}
