(「FirstVC」と言う)UINavigationControllerを含む があります。UIViewControllerこの 'FirstVC' には が含まれてUIScrollViewおり、この各ページにUIScrollView別のものを追加しましたUIViewCotroller('SecondVC' など)。このSecondVCUIWebViewには、複数のリンクを持つ が含まれています。UIViewControllerを持っている別のもの(「ThirdVC」など) をプッシュしたいと思いUIScrollViewます。しかし、同じことをしようとすると、アプリケーションがクラッシュします。適用したコードは次のとおりです。

ファーストVC

- (void)viewDidLoad{

    [super viewDidLoad];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(ShowThirdVCNotification:) name:@"ShowThirdVC" object:nil]; 

}

-(void)showAlbumNotification:(id)notificationObject{
    NSLog(@"ShowThirdVCNotification: %@", [notificationObject object]);// It's an array

    ThirdVC *controller = [[ThirdVC alloc] initWithNibName:@"ThirdVC" bundle:nil];
    [controller setImageArr:[notificationObject object]];
    [self.navigationController pushViewController:controller animated:NO];
}

/* SecondVC.view は、ロード時に FirstVC の scrollView に追加されます */

セカンドVC :

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
NSString *urlStr = [NSString stringWithFormat:@"%@", [request URL]];

    if ([[urlStr lastPathComponent] rangeOfString:@".jpg"].length) {
        [[NSNotificationCenter defaultCenter] postNotificationName:@"ShowAlbum" object:self.imageDetailArr];
        return NO;
    }
return YES;
}

UIWebViewNavigationType条件を使用して問題を解決すると思いますこれを試してください：-

 - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
        NSString *urlStr = [NSString stringWithFormat:@"%@", [request URL]];

        if ([[urlStr lastPathComponent] rangeOfString:@".jpg"].length) {

            if (navigationType == UIWebViewNavigationTypeLinkClicked)
            {
                ThirdVC *controller = [[ThirdVC alloc] initWithNibName:@"ThirdVC" bundle:nil];
                controller setImageArr:self.imageDetailArr];
                [self.navigationController pushViewController:controller animated:NO];

            }
            return NO;
        }
        return YES;
    }
