当选择 RootView 中的一行时，如何使 UISplitView 的详细信息视图中的 UIWebView 更改其内容？
我有一个基于 UISplitView 的应用程序，在详细信息视图中有一个 UIWebVIew 。当用户在根视图中的表中选择新行时，我想让它更改其内容。我在 DetailViewController 中尝试过这样的操作：
- (void)setDetailItem:(id)newDetailItem {
extern NSString *rowname;
if (detailItem != newDetailItem) {
[detailItem release];
detailItem = [newDetailItem retain];
// Update the view.
if ([rowname isEqualToString:@"About"])
[self loadFile:@"About.rtf"];
if ([rowname isEqualToString:@"Square"])
[self loadFile:@"Square.rtf"];
//And so on with every UITableView element from the RootView
if (popoverController != nil) {
[popoverController dismissPopoverAnimated:YES];
}
}
}
请帮助我！ 提前致谢！

}
}
Help me, please!
Thanks in advance!

您需要对视图控制器的引用，其中包含根视图控制器中的网络视图（您的详细视图控制器）。当选择一行时，调用 webview（详细信息）控制器中的方法并向其传递文件名、URL 等......然后它依次调用 uiwebview 方法来加载请求。

You need a reference to the viewcontroller which contains the webview (your detail view controller) within your rootview controller. when a row is selected, call a method in the webview (detail) controller and pass it a filename, URL, whatever... and it in turn calls the uiwebview method to load the request.
