iOS How to detect iPhone X, iPhone 6 plus, iPhone 6, iPhone 5, iPhone 4 by macro?

Question

How to detect device model by macro? i had using something like this but the result on the simulator alway IS_IPHONE_5

#define IS_IPAD (UI_USER_INTERFACE_IDI         


        

Answer 1

It's better not to bind your code with device types. This will lead to inflexible convoluted one. Apple wants you to think about sizes not devices. In case you need to have special sizes for devices larger than iPhone 5 such as image or font sizes, I would recommend to create a normalize class with a multiplier that grows your base size by a certain percent based on the relation between the iPhone 5 screen width and the current device size.

let BaseWidth : CGFloat = 320

class Normalizer: NSObject {
    //scale value proportional to the screen width
    class func normalize(value:CGFloat,multiplier : CGFloat = 1,maxDelta:CGFloat = 1024) -> CGFloat{
        let screenWidth = UIScreen.mainScreen().bounds.size.width
        let percent = (screenWidth - BaseWidth)/screenWidth
        let normalizedValue = value * (1 + percent) * multiplier
        return min(normalizedValue, value + maxDelta)//capped by a max value if needed
    } 
}

So in your code you will do something like that:

value = Normalizer.normalize(30)

For Swift:

struct ScreenSize
{
    static let SCREEN_WIDTH = UIScreen.main.bounds.size.width
    static let SCREEN_HEIGHT = UIScreen.main.bounds.size.height
    static let SCREEN_MAX_LENGTH = max(ScreenSize.SCREEN_WIDTH, ScreenSize.SCREEN_HEIGHT)
    static let SCREEN_MIN_LENGTH = min(ScreenSize.SCREEN_WIDTH, ScreenSize.SCREEN_HEIGHT)
}

struct DeviceType
{
    static let IS_IPHONE_4_OR_LESS =  UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH < 568.0
    static let IS_IPHONE_5 = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH == 568.0
    static let IS_IPHONE_6 = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH == 667.0
    static let IS_IPHONE_6P = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH == 736.0
}

#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) // iPhone and       iPod touch style UI

#define IS_IPHONE_5_IOS7 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 568.0f)
#define IS_IPHONE_6_IOS7 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 667.0f)
#define IS_IPHONE_6P_IOS7 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 736.0f)
#define IS_IPHONE_4_AND_OLDER_IOS7 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height < 568.0f)

#define IS_IPHONE_5_IOS8 (IS_IPHONE && ([[UIScreen mainScreen] nativeBounds].size.height/[[UIScreen mainScreen] nativeScale]) == 568.0f)
#define IS_IPHONE_6_IOS8 (IS_IPHONE && ([[UIScreen mainScreen] nativeBounds].size.height/[[UIScreen mainScreen] nativeScale]) == 667.0f)
#define IS_IPHONE_6P_IOS8 (IS_IPHONE && ([[UIScreen mainScreen] nativeBounds].size.height/[[UIScreen mainScreen] nativeScale]) == 736.0f)
#define IS_IPHONE_4_AND_OLDER_IOS8 (IS_IPHONE && ([[UIScreen mainScreen] nativeBounds].size.height/[[UIScreen mainScreen] nativeScale]) < 568.0f)

#define IS_IPHONE_5 ( ( [ [ UIScreen mainScreen ] respondsToSelector: @selector( nativeBounds ) ] ) ? IS_IPHONE_5_IOS8 : IS_IPHONE_5_IOS7 )
#define IS_IPHONE_6 ( ( [ [ UIScreen mainScreen ] respondsToSelector: @selector( nativeBounds ) ] ) ? IS_IPHONE_6_IOS8 : IS_IPHONE_6_IOS7 )
#define IS_IPHONE_6P ( ( [ [ UIScreen mainScreen ] respondsToSelector: @selector( nativeBounds ) ] ) ? IS_IPHONE_6P_IOS8 : IS_IPHONE_6P_IOS7 )
#define IS_IPHONE_4_AND_OLDER ( ( [ [ UIScreen mainScreen ] respondsToSelector: @selector( nativeBounds ) ] ) ? IS_IPHONE_4_AND_OLDER_IOS8 : IS_IPHONE_4_AND_OLDER_IOS7 )

Answer 4

I can confirm the bug goes away when you set a Launch Screen.

I kept my launch images, and added MainStoryboard to Launch Screen and the simulator recognized the devices correctly.

Answer 6

UIDeivce extension with Swift 3+ syntax.

public extension UIDevice {

    var iPhone: Bool {
        return UIDevice().userInterfaceIdiom == .phone
    }

    enum ScreenType: String {
        case iPhone4
        case iPhone5
        case iPhone6
        case iPhone6Plus
        case iPhoneX
        case Unknown
    }
    var screenType: ScreenType {
        guard iPhone else { return .Unknown}
        switch UIScreen.main.nativeBounds.height {
        case 960:
            return .iPhone4
        case 1136:
            return .iPhone5
        case 1334:
            return .iPhone6
        case 2208, 1920:
            return .iPhone6Plus
        case 2436:
            return .iPhoneX
        default:
            return .Unknown
        }
    }

}

Sample usage:

switch UIDevice().screenType {
        case .iPhone4, .iPhone5:
            // Code for iPhone 4 & iPhone 5
            break
        case .iPhone6:
            // Code for iPhone 6 & iPhone 7
            break
        case .iPhone6Plus:
            // Code for iPhone 6 Plus & iPhone 7 Plus
            break
        case .iPhoneX:
            // Code for iPhone X
            break
        default:
            break
        }
