//第一种方法
- (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.执行js语句 直接获取html文档的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.先将UIWebView的高度设为最小,然后再使用sizeThatFits就会返回刚好合适的大小
-(void)webViewDidFinishLoad:(UIWebView*)webVie{CGSize actualSize = [webView sizeThatFits:CGSizeZero];CGRect newFrame = webView.frame;newFrame.size.height = actualSize.height;webView.frame = newFrame;}
//方法4.遍历webview子视图 获取UIWebDocumentView高度即实际高度
-(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;//获取文档的高度webView.frame=webDocView.frame;//更新UIWebView 的高度}}}}
