//第一种方法
- (void)webViewDidFinishLoad:(UIWebView*)webView
{
CGFloatwebViewHeight=[webView.scrollViewcontentSize].height;
CGRectnewFrame = 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{
CGSizeactualSize = [webViewsizeThatFits:CGSizeZero];
CGRectnewFrame = 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{
CGFloatwebViewHeight =0.0f;
if([webView.subviewscount] >0)
{
UIView*scrollerView = webView.subviews[0];
if([scrollerView.subviewscount] >
0)
{
UIView*webDocView = scrollerView.subviews.lastObject;
if([webDocViewisKindOfClass:[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
}
}
}
}
