This code needs to be added to the third-party library MainPageView.

Code:

RootViewController. h

# Import <UIKit/UIKit. h> @ class MainPageView; @ interface RootViewController: UIViewController {MainPageView * mainPageView;} @ property (nonatomic, retain) MainPageView * mainPageView; @ end

 

RootViewController. m

# Import "RootViewController. h "// Add the header file # import" MainPageView. h "-(void) viewDidLoad {[super viewDidLoad]; // Do any additional setup after loading the view. mainPageView = [[MainPageView alloc] initWithFrame: CGRectMake (0, 20,320,460)]; mainPageView. backgroundColor = [UIColor lightGrayColor]; [mainPageView initDrawViewData]; self. view = mainPageView ;}
