你可以检查rangeOfString来查看单词iPad是否像这样存在。

NSString *deviceModel = (NSString*)[UIDevice currentDevice].model;

if ([deviceModel rangeOfString:@"iPad"].location != NSNotFound)  {
NSLog(@"I am an iPad");
} else {
NSLog(@"I am not an iPad");
}

很多答案都很好，但我在swift 4中使用这样的答案

创建常量 struct App { 静态let isRunningOnIpad = UIDevice.current.userInterfaceIdiom == .pad ?True: false ｝ 像这样使用 if App.isRunningOnIpad { 返回加载(from: .main, identifier: identifier) }其他{ 返回加载(from: .ipad, identifier: identifier) ｝

编辑:建议ceure简单地在UIDevice上创建一个扩展

extension UIDevice {
    static let isRunningOnIpad = UIDevice.current.userInterfaceIdiom == .pad ? true : false
}

你可以检查rangeOfString来查看单词iPad是否像这样存在。

NSString *deviceModel = (NSString*)[UIDevice currentDevice].model;

if ([deviceModel rangeOfString:@"iPad"].location != NSNotFound)  {
NSLog(@"I am an iPad");
} else {
NSLog(@"I am not an iPad");
}

在Swift 4.2和Xcode 10中

if UIDevice().userInterfaceIdiom == .phone {
    //This is iPhone
} else if UIDevice().userInterfaceIdiom == .pad { 
    //This is iPad
} else if UIDevice().userInterfaceIdiom == .tv {
    //This is Apple TV
}

如果你想检测特定的设备

let screenHeight = UIScreen.main.bounds.size.height
if UIDevice().userInterfaceIdiom == .phone {
    if (screenHeight >= 667) {
        print("iPhone 6 and later")
    } else if (screenHeight == 568) {
        print("SE, 5C, 5S")
    } else if(screenHeight<=480){
        print("4S")
    }
} else if UIDevice().userInterfaceIdiom == .pad { 
    //This is iPad
}

if(UI_USER_INTERFACE_IDIOM () == UIUserInterfaceIdiom.pad)
 {
            print("This is iPad")
 }else if (UI_USER_INTERFACE_IDIOM () == UIUserInterfaceIdiom.phone)
 {
            print("This is iPhone");
  }

在Swift中，您可以使用以下等式来确定通用应用程序上的设备类型:

UIDevice.current.userInterfaceIdiom == .phone
// or
UIDevice.current.userInterfaceIdiom == .pad

用法就像这样:

if UIDevice.current.userInterfaceIdiom == .pad {
    // Available Idioms - .pad, .phone, .tv, .carPlay, .unspecified
    // Implement your logic here
}
