iOS如何通过macros来检测iPhone X，iPhone 6 plus，iPhone 6，iPhone 5，iPhone 4？
如何通过macros来检测设备模型？ 我曾经使用过类似的东西，但模拟器上的结果总是IS_IPHONE_5
#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) #define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) #define IS_IPHONE_5 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 568.0) #define IS_IPHONE_6 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 667.0) #define IS_IPHONE_6PLUS (IS_IPHONE && [[UIScreen mainScreen] nativeScale] == 3.0f) #define IS_IPHONE_6_PLUS (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 736.0) #define IS_RETINA ([[UIScreen mainScreen] scale] == 2.0) 迅速
import UIKit public enum DisplayType { case unknown case iphone4 case iphone5 case iphone6 case iphone6plus static let iphone7 = iphone6 static let iphone7plus = iphone6plus case iphoneX } public final class Display { class var width:CGFloat { return UIScreen.main.bounds.size.width } class var height:CGFloat { return UIScreen.main.bounds.size.height } class var maxLength:CGFloat { return max(width, height) } class var minLength:CGFloat { return min(width, height) } class var zoomed:Bool { return UIScreen.main.nativeScale >= UIScreen.main.scale } class var retina:Bool { return UIScreen.main.scale >= 2.0 } class var phone:Bool { return UIDevice.current.userInterfaceIdiom == .phone } class var pad:Bool { return UIDevice.current.userInterfaceIdiom == .pad } class var carplay:Bool { return UIDevice.current.userInterfaceIdiom == .carPlay } class var tv:Bool { return UIDevice.current.userInterfaceIdiom == .tv } class var typeIsLike:DisplayType { if phone && maxLength < 568 { return .iphone4 } else if phone && maxLength == 568 { return .iphone5 } else if phone && maxLength == 667 { return .iphone6 } else if phone && maxLength == 736 { return .iphone6plus } else if phone && maxLength == 812 { return .iphoneX } return .unknown } }

注意：如果例如iPhone 6处于放大模式，则UI是iPhone 5的放大版本。这些function不是确定设备types，但是iPhone 5的显示模式是本示例中期望的结果。

对于Swift：

我使用一个类来拉实际的系统信息。 只需要确保所有的设备types是最新的。

当您设置启动屏幕时，我可以确认bug消失。
我保留了我的启动图像，并将MainStoryboard添加到启动屏幕，模拟器正确识别设备。
最好不要将您的代码与设备types绑定。 这将导致僵化的错综复杂的一个。 苹果要你考虑尺寸而不是设备。 如果您需要为iPhone 5以上的设备（如图像或字体大小）设置特殊尺寸，我build议您创build一个标准化类，其乘法器根据iPhone 5屏幕之间的关系将基本尺寸增大一定的百分比宽度和当前设备大小。
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 } }
所以在你的代码中你会做这样的事情：
value = Normalizer.normalize(30)
UIDeivce扩展与Swift 3语法。
public extension UIDevice { var iPhone: Bool { return UIDevice().userInterfaceIdiom == .phone } enum ScreenType: String { case iPhone4 case iPhone5 case iPhone6 case iPhone6Plus 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: return .iPhone6Plus default: return .Unknown } } }
示例用法：
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 default: break }

我在从iOS 7项目迁移到iOS 8项目时遇到了这个问题，因为我没有将启animation面场景添加到我的项目中。
在这种情况下，iPhone 6和6+的屏幕尺寸与iPhone 5一样。
从苹果文档中查看; 您使用启动XIB或故事板文件来指示您的应用程序在iPhone 6 Plus或iPhone 6上运行。
