UIViewController关联两个xib(Iphone5下使用xib)

#define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) : NO)

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    //self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (iPhone5) {
        self = [[super initWithNibName:@"MemberDetail_iphone5" bundle:nibBundleOrNil]autorelease];
    }
    else
    {
        self = [[super initWithNibName:@"MemberDetail" bundle:nibBundleOrNil] autorelease];
    }
    if (self) {
        // Custom initialization
    }
    return self;
}
