ios - 如何使用EGOCache更快地缓存和加载页面

Question

我的iOS应用程序中有一个UIWebView，它根据先前的操作加载不同的URL。我不希望这些页面尽快加载。我发现了类EGOCache(source)，我知道它可以将cacheData存储在library / Caches目录中。但是我不确定如何检索此缓存以更快地加载它，我看不出有什么区别。也许使用NSCache？我错过了什么？

- (void)webViewDidStartLoad:(UIWebView *)webView {
        if (webView_1) {


        NSString *urlAddress = @"http://www.apple.com";
        NSURL *url = [NSURL URLWithString:urlAddress];
        NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval: 10.0];
        [webView1 loadRequest:request];

        NSData *data0 = [NSURLConnection sendSynchronousRequest:
                        [NSURLRequest requestWithURL:url]
                                             returningResponse:nil
                                                         error:nil];

        [[EGOCache globalCache] setData:data0 forKey:@"webCache"];
        }
    }

谢谢!

好的，所以我制定了自己的方法，并使其起作用。您所要做的就是提供网址。参见以下代码:

-(void)loadPage:(NSString *)urlAddress {

    NSURL *url = [NSURL URLWithString:urlAddress];
    NSString* cachePath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0];
    NSString* file = [cachePath stringByAppendingPathComponent:@"/xxx.APPNAME/EGOCache/EGOCache.plist"];
    NSDictionary *dict =[NSDictionary dictionaryWithContentsOfFile:file];

    if ([dict objectForKey:urlAddress] )
    {
        NSData *data = [[EGOCache globalCache] dataForKey:urlAddress];
        data = [NSURLConnection sendSynchronousRequest:
                [NSURLRequest requestWithURL:url]
                                     returningResponse:nil
                                                 error:nil];
        NSLog(@"loading from cache %@",urlAddress);

    }else{
        NSData  *data = [NSURLConnection sendSynchronousRequest:
                         [NSURLRequest requestWithURL:url]
                                              returningResponse:nil
                                                          error:nil];
        [[EGOCache globalCache] setData:data forKey:urlAddress];
        NSLog(@"saving cache %@",urlAddress);
        [[EGOCache globalCache] setDefaultTimeoutInterval:60*60*24*4]; //timeout (4 days)
    }
    NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval: 10.0];

    [webView loadRequest:request];
}
