the app delegate.h file is as follows

#import <UIKit/UIKit.h>

@class AFAViewController;
@class OpenInChromeController;
@class AFABarcodeScanner;


@interface AFAAppDelegate : NSObject <UIApplicationDelegate,UIAlertViewDelegate>
{

    OpenInChromeController *openInChromeController_;
    AFABarcodeScanner *bs;

}



@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic)AFAViewController *viewController;

@property(strong,nonatomic)AFABarcodeScanner *bs;



@end

the app delegate.m file is as follows

#import "AFAAppDelegate.h"
#import "AFAViewController.h"

    [self.view addSubview:vc.view];



    return YES;
}




@end

i would like open the new view inside the custom url function. When the request is obtained from external web page the view inside the application delegate must be opened.

获取 AFAViewController(self.viewController) 的实例并将子视图添加到此视图中,或者尽可能将 AFABarcodeScanner 呈现为模型

There are couple of ways to achieve it:

First: AppDelegate has a property window. A window is a view, so you can do

[self.window addSubview:newView];

Second: a view controller can reach the window without dealing with the app delegate.

[controller.view addSubview:overlayView];
