API来确定是否在iPhone或iPad上运行 [英] API to determine whether running on iPhone or iPad

问题描述

有没有API用于在运行时检查您是在iPhone或iPad上运行？

Is there an API for checking at runtime whether you are running on an iPhone or an iPad?

我可以想到的一种方法是使用：

One way I can think of would be to use:

[[UIDevice currentDevice] model];

检测字符串@iPad的存在 - 这看起来有点脆弱。

And detect the existence of the string @"iPad" - which seems a bit fragile.

在3.2 SDK中，我看到 UIDevice 也有一个属性，这是我正在寻找的，对于3.2之前的工作（显然）：

In the 3.2 SDK, I see that UIDevice also has a property which is really what I'm looking for, but doesn't work for pre-3.2 (obviously):

[[UIDevice currentDevice] userInterfaceIdiom]; 

有没有其他方法可以检查通用应用程序是否存在@iPad p>

Are there other ways than checking for the existence of @"iPad" for a universal app?

推荐答案

Checkout UI_USER_INTERFACE_IDIOM 。

Checkout UI_USER_INTERFACE_IDIOM.

返回当前设备支持的接口idiom。

Returns the interface idiom supported by the current device.

返回值 br>
UIUserInterfaceIdiomPhone （如果设备是iPhone或iPod touch）或 UIUserInterfaceIdiomPad 。

Return Value
UIUserInterfaceIdiomPhone if the device is an iPhone or iPod touch or UIUserInterfaceIdiomPad if the device is an iPad.

UIUserInterfaceIdiom

用于当前设备

typedef enum {
   UIUserInterfaceIdiomPhone,
   UIUserInterfaceIdiomPad,
} UIUserInterfaceIdiom;
