确定iOS设备是32位还是64位 [英] Determine if iOS device is 32- or 64-bit

问题描述

有谁知道一个简单的方法来判断iOS7设备是否具有32位或64位硬件？我不是指编程方式，我只是指通过设置，型号，第三方应用程序等。

Does anyone know of an easy way to tell if an iOS7 device has 32- or 64-bit hardware? I don't mean programmatically, I just mean via settings, model number, 3rd-party app, etc.

我遇到的问题我怀疑是64-有点相关。 Apple的建议是在64位模拟器上进行测试，但也要在实际的64位设备上进行测试，但之后并没有说明如何确定。我可以编写一个测试应用程序来检查sizeof（int）或者其他什么，但是必须有一些方法可以让技术支持知道他们正在使用它们。

I'm having a problem that I suspect is 64-bit related. Apple's advice is to test on the 64-bit simulator but also on an actual 64-bit device, but then doesn't say anything about how to determine that. I can write a test app to check sizeof(int) or whatever, but there's got to be some way for, say, tech support to know what they're working with.

推荐答案

没有其他官方方式来确定它。您可以使用以下代码确定它：

There is no other "official" way to determine it. You can determine it using this code:

if (sizeof(void*) == 4) {
    NSLog(@"32-bit App");
} else if (sizeof(void*) == 8) {
    NSLog(@"64-bit App");
}
