How can I chain audio in button action?

I can use for WKWebview of html page and javascript that is move successfuly,but I wanna use native language is Objective-c.

#import <UIKit/UIKit.h>
#import <AVKit/AVKit.h>
#import <AVFOundation/AVFoundation.h>
#import <NCMB/NCMB.h>

@interface ViewControllerA ()
@property (weak, nonatomic) IBOutlet UIWebView *Grandcross_Video;
@end

@implementation ViewControllerA

- (void)viewDidLoad {
    [super viewDidLoad];
    NSString *path = [[NSBundle mainBundle]pathForResource:@"Video" ofType:@"html"];
    [_Grandcross_Video loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:path]]];
    CGRect display = [[UIScreen mainScreen]bounds];
    if(display.size.height == 736){
        _Grandcross_Video.frame = CGRectMake(0, 0, self.view.frame.size.width, 692);
    }
}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
}

@end

It's a most simply bundle html is set as ViewControllerA.m

And at first open General of project file name is clicked then scrolling down that page's LInked Framework and Libraries, then click + button to add the some framework.

If native way for stream on objective-c is able to be set, tell me about it.

I'll wait some answer for me.

We will never fail to reach it.

Thak you!
