comment vérifier la taille de l'écran de l'iphone 4 et l'iphone 5 par programmation dans swift

Question

comment vérifier la taille de l'écran de l'iphone 4 et l'iphone 5 par programmation dans swift

je dois remplacer cet objectif-C à Swift. Quelqu'un aurait-il des suggestions sur la façon de le transférer?

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

solution Alternative avec UIScreen extension ( iOS 8 et les versions ultérieures):

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
    }
}

Utilisation:

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

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.écran principal().lier.taille.la hauteur fournira la hauteur de l'appareil. En utilisant cette valeur, nous pouvons vérifier l'appareil iphone particulier.

En plus de la manière proposée, Une façon de le faire est d'utiliser la structure de la manière suivante.

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_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
}

dites-moi si ça aide.

essayez d'utiliser ceci:

créer un UIViewController+Extension.swift fichier: et mis dans le code ci-dessous:

enum DeviceTypeModel{
    case iphoneX
    case iphone8Plus
    case iphone8
    case iphoneSE //SE is the like iphone 5 and iphone 5s
    case iphone4s
}

extension UIViewController{
    func runOnTheDeviceType(_ completion: (DeviceTypeModel) -> Void) {
        if UIDevice().userInterfaceIdiom == .phone{
            switch UIScreen.main.nativeBounds.height{
            case 2436:
                completion(.iphoneX)
            case 1920:
                completion(.iphone8Plus)
            case 1334:
                completion(.iphone8)
            case 1136:
                completion(.iphoneSE)
            default:
                completion(.iphone4s)
            }
        }
    }
}

et utilisez-le dans votre viewController .swift comme ceci:

class ChatViewController: UIViewController{
      override func viewDidLoad() {
        super.viewDidLoad()
          runOnTheDeviceType { devices in
            switch devices{
            case .iphoneSE:
                //do something
            case .iphone4s:
                //do something
            default:
                //do something
            }
        }
      }
}

, vous pouvez ajouter plus de cas si vous voulez le faire. En profiter.

vous pouvez également essayer ce code ci-dessous:

        imgHeight.constant = 150;
    }
    else if (IS_IPAD) {
        imgHeight.constant = 300;
    }
    else if (IS_IPHONE5) {
        imgHeight.constant = 170;
    }
    else {
        imgHeight.constant = 200;
    }
