UIWebview 适配 计算webview高度

- (void)webViewDidFinishLoad:(UIWebView *)webView

{

    const CGFloat defaultWebViewHeight = 22.0;

    //reset webview size

    CGRect originalFrame = webView.frame;

    webView.frame = CGRectMake(originalFrame.origin.x, 270, 320, defaultWebViewHeight);

    

    CGSize actualSize = [webView sizeThatFits:CGSizeZero];

    if (actualSize.height <= defaultWebViewHeight) {

        actualSize.height = defaultWebViewHeight;

    }

    CGRect webViewFrame = webView.frame;

    webViewFrame.size.height = actualSize.height;

    webView.frame = webViewFrame;

    NSLog(@"ceshi   %f",webView.frame.size.height);
