IOS计算UIWebView的实际高度

UIWebView*_detailWebView=[[UIWebView alloc]initWithFrame:CGRectMake(0,0, 320, 480)];

 _detailWebView.delegate=self;

[_detailWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http:www.baidu.com"]]];

[_productDetailSV addSubview:_detailWebView];

    

-(void)webViewDidFinishLoad:(UIWebView*)webVie{

    CGSize actualSize = [_detailWebView sizeThatFits:CGSizeZero];

    CGRect newFrame = _detailWebView.frame;

    newFrame.size.height = actualSize.height;

    _detailWebView.frame = newFrame;

    _productDetailSV.contentSize=CGSizeMake(320,480);

}
