iPhone 上 UIWebView 的 URL 过滤
有人可以解释一下我如何让它工作吗： http://www .icab.de/blog/2009/08/18/url-filtering-with-uiwebview-on-the-iphone/
我尝试在项目中制作“FilteredWebCache.h”和“FilteredWebCache.m”文件，但它说“FilterManager.h”不存在。我打算如何处理这些文件？
我将其放入 viewDidLoad 中：
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = [paths objectAtIndex:0];
NSString *path = docDir; // the path to the cache file
NSUInteger discCapacity = 10*1024*1024;
NSUInteger memoryCapacity = 512*1024;
FilteredWebCache *cache = [[FilteredWebCache alloc] initWithMemoryCapacity:memoryCapacity diskCapacity:discCapacity diskPath:path];
[NSURLCache setSharedURLCache:cache];
[cache release];
Can someone please shed some light on how I would get this to work:

I tried making the "FilteredWebCache.h" and "FilteredWebCache.m" files in my project, but it said that "FilterManager.h" did not exist. What am I meant to do with those files?
This I put in viewDidLoad:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = [paths objectAtIndex:0];
NSString *path = docDir; // the path to the cache file
NSUInteger discCapacity = 10*1024*1024;
NSUInteger memoryCapacity = 512*1024;
FilteredWebCache *cache = [[FilteredWebCache alloc] initWithMemoryCapacity:memoryCapacity diskCapacity:discCapacity diskPath:path];
[NSURLCache setSharedURLCache:cache];
[cache release];

您需要自己编写FilterManager类（FilterManager.m和FilterManager.h）。那篇文章说：
示例代码似乎将其称为 FilterMgr 而不是 FilterManager，并且看起来您需要提供一个 shouldBlockURL: 方法来决定阻止什么内容。
You need to write the FilterManager class yourself (FilterManager.m and FilterManager.h). That post says:
The example code seems to call it FilterMgr instead of FilterManager, and it looks like you need to provide a shouldBlockURL: method that decides what gets blocked.
