iPhone check firmware version

Question

HI all

I want to make one app for iPhone 2.2.* and for version 3.0. Some method in 2.2* is deprecated in 3.0. ( like UITableViewCell setText and setLabel )

Is there any way to check which firmware version is used on iPhone and to set different method to use

Answer 1

You will need to use pre-processor directives for the conditional compilation such as __IPHONE_3_0 and build two separate executables.

For example:

 #ifdef __IPHONE_3_0
 // code specific to version 3
 #else
 // code specific to version 2
 #end

If you need to detect the version at run-time you can use [[UIDevice currentDevice] systemVersion]. It returns the string with the current version of the iPhone OS.
