Hi all,
I want to identify the device on which my application is installed. That means, when I install the app on the iphone, it should tell me the device information. The information is like, the device is 2G, 3G or 3GS.
Currently I am getting only model, name, systemName, systemVersion of the device.
I want to know the device is 2G , 3G or 3GS.
please help me.
In the past history of Mac programming, this was always considered the wrong question.
What you really need to know is a more specific piece of information. Ask a much more narrow question for each behavioral decision in your code. For example, you may need to know if the device has GPS or not. Another is that you shouldn't decide how to use the OpenGL stack based on what model device it is, but rather on the OpenGL capabilities/extensions information that is provided.
The information you're getting now is from UIDevice, which is an unfortunately poorly designed API. It provides you with exactly the wrong information in the worst possible format -- strings.
Erica Sadun has an extension to UIDevice that may be useful here. It's just a wrapper for sysctlbyname("hw.machine", ...). This property is different for each model.
But again, this is usually the wrong question.
