我开发了一个应用程序，在其中我将一个 viewcontroller 的视图添加到另一个 viewcontroller 的视图中。rootviewcontroller 有许多按钮，单击事件将不同的 viewcontroller 的视图添加到 rootviewcontroller 的视图中。其他按钮工作正常。但一个按钮使应用程序崩溃。当我们单击该按钮时，它会添加 viewconroller，它有一个 web 视图，其中加载了一个静态字符串。

if(interfaceOrientation != UIInterfaceOrientationPortrait && interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown)
{
    self.uiwebViewAboutUs = self.webview_ld;
    self.view = self.landscape_ipad;
}
else{
    self.uiwebViewAboutUs = self.webview_pt;
    self.view = self.portrait_ipad;
}


-(void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    NSString *content = @"Lorem ipsum dolor sit er elit lamet, consectetaur cillium adipisicing pecu, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

    [self.uiwebViewAboutUs loadHTMLString:content baseURL:nil];
}

崩溃指向从 XIB 加载 WebView 的问题。您能否右键单击 XIB 中的 WebView 并验证连接？如果这没有帮助，您可以删除并重新添加 WebView 吗？

崩溃指向正在发送的无法识别的选择器。你的对象不知道如何对它做出反应。无论按钮发送的选择器是什么，目标都不会实现它。
