如何在swift中以编程方式检查iphone 4和iphone 5的屏幕尺寸

Question

我需要将此Objective-C替换为Swift.有没有人对如何转让有任何建议？

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
{
    CGSize result = [[UIScreen mainScreen] bounds].size;
    if(result.height == 480)
    {
        // iPhone Classic
    }
    if(result.height == 568)
    {
        // iPhone 5
    }
}

Xcode 9•Swift 4

extension UIDevice {
    var iPhoneX: Bool {
        return UIScreen.main.nativeBounds.height == 2436
    }
    var iPhone: Bool {
        return UIDevice.current.userInterfaceIdiom == .phone
    }
    enum ScreenType: String {
        case iPhones_4_4S = "iPhone 4 or iPhone 4S"
        case iPhones_5_5s_5c_SE = "iPhone 5, iPhone 5s, iPhone 5c or iPhone SE"
        case iPhones_6_6s_7_8 = "iPhone 6, iPhone 6S, iPhone 7 or iPhone 8"
        case iPhones_6Plus_6sPlus_7Plus_8Plus = "iPhone 6 Plus, iPhone 6S Plus, iPhone 7 Plus or iPhone 8 Plus"
        case iPhones_X_XS = "iPhone X or iPhone XS"
        case iPhone_XR = "iPhone XR"
        case iPhone_XSMax = "iPhone XS Max"
        case unknown
    }
    var screenType: ScreenType {
        switch UIScreen.main.nativeBounds.height {
        case 960:
            return .iPhones_4_4S
        case 1136:
            return .iPhones_5_5s_5c_SE
        case 1334:
            return .iPhones_6_6s_7_8
        case 1792:
            return .iPhone_XR
        case 1920, 2208:
            return .iPhones_6Plus_6sPlus_7Plus_8Plus
        case 2436:
            return .iPhones_X_XS
        case 2688:
            return .iPhone_XSMax
        default:
            return .unknown
        }
    }
}

print("screenType:", UIDevice.current.screenType)

使用UIScreen扩展的替代解决方案(iOS 8及更高版本):

extension UIScreen {

    enum SizeType: CGFloat {
        case Unknown = 0.0
        case iPhone4 = 960.0
        case iPhone5 = 1136.0
        case iPhone6 = 1334.0
        case iPhone6Plus = 1920.0
    }

    var sizeType: SizeType {
        let height = nativeBounds.height
        guard let sizeType = SizeType(rawValue: height) else { return .Unknown }
        return sizeType
    }
}

用法:

if UIScreen.mainScreen().sizeType == .iPhone4 {
    // Make specific layout for small devices.
}

Answer 3

if UIDevice().userInterfaceIdiom == .Phone {
    switch UIScreen.mainScreen().bounds.size.height{
    case 480:
        print("iPhone 4S")
    case 568:
        print("iPhone 5")
    default:
        print("other models")
    }
}

UIScreen.mainScreen().bounds.size.height将提供设备的高度.通过使用此值,我们可以检查特定的iPhone设备.

iPhone XS，iPhone XS Max和iPhone XR的新更新

extension UIDevice {
    var iPhoneX: Bool {
        return UIScreen.main.nativeBounds.height == 2436
    }
    var iPhone: Bool {
        return UIDevice.current.userInterfaceIdiom == .phone
    }
    enum ScreenType: String {
        case iPhone4_4S = "iPhone 4 or iPhone 4S"
        case iPhones_5_5s_5c_SE = "iPhone 5, iPhone 5s, iPhone 5c or iPhone SE"
        case iPhones_6_6s_7_8 = "iPhone 6, iPhone 6S, iPhone 7 or iPhone 8"
        case iPhones_6Plus_6sPlus_7Plus_8Plus = "iPhone 6 Plus, iPhone 6S Plus, iPhone 7 Plus or iPhone 8 Plus"
        case iPhoneXR = "iPhone XR"
        case iPhoneX_iPhoneXS = "iPhone X,iPhoneXS"
        case iPhoneXSMax = "iPhoneXS Max"
        case unknown
    }
    var screenType: ScreenType {
        switch UIScreen.main.nativeBounds.height {
        case 960:
            return .iPhone4_4S
        case 1136:
            return .iPhones_5_5s_5c_SE
        case 1334:
            return .iPhones_6_6s_7_8
        case 1792:
            return .iPhoneXR
        case 1920, 2208:
            return .iPhones_6Plus_6sPlus_7Plus_8Plus
        case 2436:
            return .iPhoneX_iPhoneXS
        case 2688:
            return .iPhoneXSMax
        default:
            return .unknown
        }
    }
}

print（“ screenType：”，UIDevice.current.screenType.rawValue）

这是我使用Xcode 10 + Swift 4 + iPhone XS / XS Max / XR的方法

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
    static let IS_IPHONE_X          = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH == 812
    static let IS_IPAD              = UIDevice.current.userInterfaceIdiom == .pad && ScreenSize.SCREEN_MAX_LENGTH   == 1024.0
    static let IS_IPAD_PRO          = UIDevice.current.userInterfaceIdiom == .pad && ScreenSize.SCREEN_MAX_LENGTH   == 1366.0
    static let IS_IPHONE_XSMAX      = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH == 2688
    static let IS_IPHONE_XR         = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.SCREEN_MAX_LENGTH == 1792
}
