Instagram IPHONE HOOKS - 该应用程序尚未打开

Question

我试图从我自己的应用程序中打开Instagram，尝试获取标记为“brazil”的照片列表。但Instagram并没有开放。请在此处查看代码段。

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    //Load URL
    NSURL *instagramURL = [NSURL URLWithString:@"instagram://tag?name=brazil"];
   if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
        [[UIApplication sharedApplication] openURL:instagramURL];
   }

    NSURLRequest *instagramRequest = [NSURLRequest requestWithURL:instagramURL];

    [instagramWebView loadRequest:instagramRequest];
}

提前致谢！
