前段时间需要修改webView背景色,上stackoverflow搜了很久没有找到结果,百度搜索,各种转载,各种坑爹,搜出来的都只有字体大小和字体颜色,页面背景没有看到,本人发布方法,希望可以帮助到更多人 在webView的delegate回调方法-webViewDidFinishLoad:(UIWebView*)webView;中写上一下语句即可 //字体大小 [webView stringByEvaluatingJavaScriptFromString:@"document.getElementsByTagName(‘body‘)[0].style.webkitTextSizeAdjust= ‘330%‘"]; //字体颜色 [webView stringByEvaluatingJavaScriptFromString:@"document.getElementsByTagName(‘body‘)[0].style.webkitTextFillColor= ‘gray‘"]; //页面背景色 [webView stringByEvaluatingJavaScriptFromString:@"document.getElementsByTagName(‘body‘)[0].style.background=‘#2E2E2E‘"]; 之前把方法写在init里怎么都不行 ,原来得写在delegate里啊 (上边的才是正确的) - (void)initWebView { if (!self.myWebView){ self.myWebView = [[UIWebView alloc] initWithFrame:self.view.bounds]; } self.myWebView.delegate = self; self.myWebView.opaque = NO; //不设置这个值 页面背景始终是白色 self.myWebView.backgroundColor = [UIColor clearColor]; self.myWebView.scalesPageToFit = NO; //禁止用户缩放页面 self.myWebView.dataDetectorTypes = UIDataDetectorTypePhoneNumber|UIDataDetectorTypeLink; self.myWebView.scrollView.pagingEnabled = YES; self.myWebView.scrollView.contentInset = UIEdgeInsetsMake(0, 0,0, 0); self.myWebView.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight; [self.view addSubview:self.myWebView]; NSString *jsString = [[NSString alloc] initWithFormat:@"document.body.style.fontSize=%f;document.body.style.color=%@",16.0,[color webColorString]]; [self.myWebView stringByEvaluatingJavaScriptFromString:jsString]; }
