我有一款应用可以在iPhone和iPod Touch上运行,也可以在Retina iPad和其他设备上运行,但需要做一些调整。我需要检测当前设备是否是iPad。我可以用什么代码来检测用户是否在我的UIViewController中使用iPad,然后相应地改变一些东西?

斯威夫特的另一种方式:

//MARK: -  Device Check
let iPad = UIUserInterfaceIdiom.Pad
let iPhone = UIUserInterfaceIdiom.Phone
@available(iOS 9.0, *) /* AppleTV check is iOS9+ */
let TV = UIUserInterfaceIdiom.TV

extension UIDevice {
    static var type: UIUserInterfaceIdiom 
        { return UIDevice.currentDevice().userInterfaceIdiom }
}

用法:

if UIDevice.type == iPhone {
    //it's an iPhone!
}

if UIDevice.type == iPad {
    //it's an iPad!
}

if UIDevice.type == TV {
    //it's an TV!
}

为什么这么复杂?我就是这么做的…

斯威夫特4:

var iPad : Bool {
    return UIDevice.current.model.contains("iPad")
}

这样你就可以说if iPad {}

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
}

你也可以用这个

#define IPAD UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad
...
if (IPAD) {
   // iPad
} else {
   // iPhone / iPod Touch
}

斯威夫特的另一种方式:

//MARK: -  Device Check
let iPad = UIUserInterfaceIdiom.Pad
let iPhone = UIUserInterfaceIdiom.Phone
@available(iOS 9.0, *) /* AppleTV check is iOS9+ */
let TV = UIUserInterfaceIdiom.TV

extension UIDevice {
    static var type: UIUserInterfaceIdiom 
        { return UIDevice.currentDevice().userInterfaceIdiom }
}

用法:

if UIDevice.type == iPhone {
    //it's an iPhone!
}

if UIDevice.type == iPad {
    //it's an iPad!
}

if UIDevice.type == TV {
    //it's an TV!
}

注意:如果你的应用只针对iPhone设备,在iPhone兼容模式下运行的iPad将为以下语句返回false:

#define IPAD     UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad

检测实体iPad设备的正确方法是:

#define IS_IPAD_DEVICE      ([(NSString *)[UIDevice currentDevice].model hasPrefix:@"iPad"])
