API来确定是否在iPhone或iPad上运行

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 。

Checkout UI_USER_INTERFACE_IDIOM.

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.

用于当前设备

typedef enum {
   UIUserInterfaceIdiomPhone,
   UIUserInterfaceIdiomPad,
} UIUserInterfaceIdiom;
