使網(wǎng)頁(yè)滑動(dòng)順暢

self.webView.scrollView.decelerationRate = UIScrollViewDecelerationRateNormal;

如果點(diǎn)擊加載網(wǎng)頁(yè)后，左滑返回上一界面手勢(shì)失效，試過(guò)這種方法都無(wú)效，可能使前端web 寬度設(shè)置問(wèn)題。

如果在網(wǎng)頁(yè)請(qǐng)求失敗后，想在
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error，
但如果在請(qǐng)求過(guò)程中左滑返回，也會(huì)走didFailLoadWithError代理方法，這時(shí)可以判斷 error code if ([error code] == NSURLErrorCancelled) return;

設(shè)置Agent

NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];    
  
NSString *paramsString = [NSString stringWithFormat:@"AppName/%@",[infoDic objectForKey:@"CFBundleShortVersionString"]];   

NSDictionary *dictionary = @{@"UserAgent": paramsString};
    [[NSUserDefaults standardUserDefaults] registerDefaults:dictionary];   

［url scheme］ [url host] [url port] [url absoluteString]等相關(guān)概念區(qū)分，
