Question

我有两个带有UIWebViews场景的视图控制器。主要的一个名为MainViewController，应该调用第二个名为ViewController，当用户在其中添加PostPicPopUp链接时调出该场景。在MainViewController中我有：

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{

    NSURL *urL=request.URL;
    NSString *urlStr=[urL absoluteString];
    //NSLog(@"URLL %@",urlStr);

    if ([urlStr rangeOfString:@"PostPicPopUp"].location == NSNotFound) {
        return YES;
    } else {
        return NO;
    }
}

所以我需要之前的代码

return YES

您可以使用下面的代码手动调用您的视图控制器：

// Objective-C
ViewController *controller = [[ViewController alloc] init];    
[self controller animated:YES completion:nil];

// Using storyboard
ViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"MyViewControllerIdentifier"];
[self presentViewController:controller animated:YES completion:nil];

在shouldStartLoadWithRequest中调用视图控制器
