iPad 2检测 [英] iPad 2 detection

问题描述

由于我没有iPad 2，因此在调用[[UIDevice currentDevice] model]时我需要知道它返回的内容。我认为它只返回iPad，但似乎我错了。

Since I don't have iPad 2, I need to know what it returns when calling [[UIDevice currentDevice] model]. I thought it returns just "iPad" but it seems I'm wrong.

有人可以告诉我吗？

谢谢

推荐答案

检查带相机的iPad。

Check for an iPad with a camera.

BOOL isIPad2 = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad &&
                [UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]);

请注意，检测特定功能通常会更好，而不是基于模型/版本检测进行全面假设。例如，如果您需要相机，请明确测试相机;如果您需要根据可用的RAM量调整UI质量，请测试物理RAM ;另请注意我写的评论，强调使用的危险性模型检测。

Note that it is generally better to detect specific features rather than make blanket assumptions based on model/version detection. For instance, if you need a camera, then test for the camera explicitly; if you need to tweak the UI quality based on the amount of RAM available, test for physical RAM; etc. Also note a comment I wrote that highlights the dangers of using model detection.
