我想检测 iOS 设备屏幕尺寸并基于此加载不同的 Storyboard。知道如何在 Swift 中实现这一点。

有没有像

if #available(iOS 9.0, *) {
 // load zoomed storyboard 
}else{
 // load standard storyboard 
}

最佳答案

尝试以下操作。您可以轻松检查正在使用的是哪个 iDevice。您甚至可以判断该应用是否正在模拟器上运行。

private let DeviceList = [
/* iPod 5 */          "iPod5,1": "iPod Touch 5",
/* iPhone 4 */        "iPhone3,1":  "iPhone 4", "iPhone3,2": "iPhone 4", "iPhone3,3": "iPhone 4",
/* iPhone 4S */       "iPhone4,1": "iPhone 4S",
/* iPhone 5 */        "iPhone5,1": "iPhone 5", "iPhone5,2": "iPhone 5",
/* iPhone 5C */       "iPhone5,3": "iPhone 5C", "iPhone5,4": "iPhone 5C",
/* iPhone 5S */       "iPhone6,1": "iPhone 5S", "iPhone6,2": "iPhone 5S",
/* iPhone 6 */        "iPhone7,2": "iPhone 6",
/* iPhone 6 Plus */   "iPhone7,1": "iPhone 6 Plus",
/* iPhone 6S */       "iPhone8,1": "iPhone 6S",
/* iPhone 6S Plus */  "iPhone8,2": "iPhone 6S Plus",
/* iPad 2 */          "iPad2,1": "iPad 2", "iPad2,2": "iPad 2", "iPad2,3": "iPad 2", "iPad2,4": "iPad 2",
/* iPad 3 */          "iPad3,1": "iPad 3", "iPad3,2": "iPad 3", "iPad3,3": "iPad 3",
/* iPad 4 */          "iPad3,4": "iPad 4", "iPad3,5": "iPad 4", "iPad3,6": "iPad 4",
/* iPad Air */        "iPad4,1": "iPad Air", "iPad4,2": "iPad Air", "iPad4,3": "iPad Air",
/* iPad Air 2 */      "iPad5,1": "iPad Air 2", "iPad5,3": "iPad Air 2", "iPad5,4": "iPad Air 2",
/* iPad Mini */       "iPad2,5": "iPad Mini", "iPad2,6": "iPad Mini", "iPad2,7": "iPad Mini",
/* iPad Mini 2 */     "iPad4,4": "iPad Mini", "iPad4,5": "iPad Mini", "iPad4,6": "iPad Mini",
/* iPad Mini 3 */     "iPad4,7": "iPad Mini", "iPad4,8": "iPad Mini", "iPad4,9": "iPad Mini",
