I know this topic might be a very commonly asked question but I still couldn’t get the solution.
Firstly, I know there are two methods to check OS version
1)
[[UIDevice currentDevice] systemVersion]
This is definitely not something I’m looking for because this is used during runtime, what I’m looking at is something can be done during compilation.
2)
#if __IPHONE_6_0
// do something
#endif
This is something that I was hoping it to work but it doesn’t. 2 problems here:
i) Running on iPhone simulator version 5.0 and I noticed #if __IPHONE_6_0 is returning TRUE value. I thought it suppose to be TRUE only if the version is 6.0 or above?
ii) Same thing happen when I tested it on iPad simulator. Does that macro works on iPad as well?
The reason that I want it to be done during compilation is because I’m using the latest iOS 6.0 Social Framework but I would like my app to support on older version (min 4.3) as well. Problem is part of my codes are using Social Framework stuffs. So I have to do a macro check to know whether this device support Social Framework or not, if not don’t compile that particular Social Framework’s codes. If I don’t do that, I will be getting error during compilation because OS that below version 6 does not know what is Social Framework.
Looking forward to get some solutions here.
You can’t use macros for this purpose because when you compile macros use YOUR version and it will not work for other devices(it seems to be obvious…)
