在通用（iPad、iPhone、iPod）应用程序开发中测试不同的屏幕分辨率
我注意到，当向应用程序商店提交通用应用程序时，需要支持多种屏幕分辨率。我认为 iPhone/iPod：320x460、320x480、640x960 和 iPad 768x1024。
当我在 Xcode 中指定通用应用程序开发时，模拟器的分辨率为 320x480。要查看768x1024屏幕分辨率，我可以将目标设置更改为iPad，但如何测试320x460和640x960分辨率？
我的默认解决方案是针对 iPad，并手动破解我的代码，例如： SCREEN_WIDTH=640, SCREEN_HEIGHT=960; 但模拟器上肯定应该有一个设置！
在一个相关问题中，有什么方法可以从模拟器中获取屏幕截图（除了 command-shift-3 和裁剪生成的图像之外）？
提前致谢。
I notice when submitting a Universal app to the app store, there are various screen resolutions to support. I think iPhone/iPod: 320x460, 320x480, 640x960 and iPad 768x1024.
When I specify Universal app development in Xcode, the simulator has a resolution of 320x480. To view 768x1024 screen resolution, I can change the target setting to iPad, but how to test 320x460 and 640x960 resolutions?
My default solution is to target iPad, and manually hack my code, e.g.: SCREEN_WIDTH=640, SCREEN_HEIGHT=960; but surely there should be a setting on the simulator for this!?
In a related question, is there any way to get screen captures off the simulator (apart from command-shift-3 and cropping the resulting image)?
Thanks in advance.

640x960 是 iPhone 4。您只需在模拟器设备菜单中选择“iPhone 4”即可。您会注意到所有内容都是两倍大（除非您的计算机屏幕很小）。
iPhone 4 仍会根据 [
[UIScreen mainScreen] applicationFrame].size表示其屏幕为 320x480，请参阅 此处进行讨论。460x320 是标准 iPhone/iPod Touch 屏幕减去状态栏的尺寸。您不需要单独支持 480x320。
注意：在最近的模拟器版本中，“iPhone 4”选项已重命名为“iPhone（Retina）”。
我认为没有更好的方法来从模拟器中获取屏幕截图。
640x960 is an iPhone 4. You can simply select "iPhone 4" in the simulator device menu. You'll notice everything is twice as big (unless your computer has a small screen).
The iPhone 4 will still say its screen is 320x480 according to [
[UIScreen mainScreen] applicationFrame].sizesee here for a discussion.460x320 is the standard iPhone/iPod Touch screen minus the size of the status bar. You don't need to support it separately from 480x320.
Note: The "iPhone 4" option has been renamed "iPhone (Retina)" in recent simulator versions.
I don't think there is a better way to get screen captures off the simulator.
