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];
