如何通过宏检测设备型号？
我使用过类似的东西，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)
Swift
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 处于缩放模式，UI 是 iPhone 5 的放大版本。这些功能不是确定设备类型，而是确定显示模式，因此 iPhone 5 是本示例中所需的结果。
