//第一種方法
- (void)webViewDidFinishLoad:(UIWebView *)webView { CGFloat webViewHeight=[webView.scrollView contentSize].height; CGRect newFrame = webView.frame; newFrame.size.height = webViewHeight; webView.frame = newFrame; _webTablewView.contentSize = CGSizeMake(320, newFrame.size.height + 64 + KWIDTH - 100); }
//2.執行js語句 直接獲取html文檔的dom高度
- (void)webViewDidFinishLoad:(UIWebView *)webView{ CGFloatwebViewHeight =[[webViewstringByEvaluatingJavaScriptFromString:@document.body.offsetHeight]floatValue]; // CGFloat webViewHeight= [[webViewstringByEvaluatingJavaScriptFromString:@document.body.scrollHeight]floatValue]; CGRectnewFrame = webView.frame; newFrame.size.height= webViewHeight; webView.frame= newFrame; }
//方法3.先將UIWebView的高度設為最小,然後再使用sizeThatFits就會返回剛好合適的大小
-(void)webViewDidFinishLoad:(UIWebView*)webVie{ CGSize actualSize = [webView sizeThatFits:CGSizeZero]; CGRect newFrame = webView.frame; newFrame.size.height = actualSize.height; webView.frame = newFrame; }
//方法4.遍歷webview子視圖 獲取UIWebDocumentView高度即實際高度
-(void)webViewDidFinishLoad:(UIWebView *)webView{ CGFloat webViewHeight = 0.0f; if([webView.subviews count] > 0) { UIView *scrollerView = webView.subviews[0]; if([scrollerView.subviews count] > 0) { UIView *webDocView = scrollerView.subviews.lastObject; if ([webDocView isKindOfClass:[NSClassFromString(@UIWebDocumentView)class]]) { webViewHeight = webDocView.frame.size.height;//獲取文檔的高度 webView.frame=webDocView.frame; //更新UIWebView 的高度 } } } }
