Backward compatibility of Xcode OSX

How to use features such as viewDidLoad or appDidBecomeActive in Xcode 4.6.1 for OSX 10.8, which are available only for OSX 10.10 and above. Please suggest the alternative ways to use these functions.

I'd override setView

@interface MyViewController : NSViewController 
@end

@implementation MyViewController 
- (void)setView:(NSView*)v {
    super.view = v;
    // if we're running on 10.8 or older…
    if (NSAppKitVersionNumber <= NSAppKitVersionNumber10_8) {
        [self viewDidLoad]; // call viewDidLoad (added in 10.9)
    }
}
@end

To expand on Ken Thomas's comment; this is the code that I use:

- (void)loadView
{
    [super loadView];

    // if we're running on 10.8 or older…
    if (NSAppKitVersionNumber <= NSAppKitVersionNumber10_8) {
        [self viewDidLoad]; // call viewDidLoad (added in 10.9)
    }
}

//
// This will be called by loadView pre-10.9; directly otherwise
//
- (void)viewDidLoad {
    // --- YOUR CODE HERE ---
}   // viewDidLoad
