UIViewController关联两个xib(Iphone5上使用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;}
