uiwebview加载网页后根据内容设置大小

-（void）setWebView{

 web=[[UIWebView alloc]initWithFrame:CGRectMake(5, imageView.frame.origin.y+imageView.frame.size.height,310, 0)];

    web.userInteractionEnabled =NO;

    NSString* url=self.gamemodel.appIntroduce;

    NSURLRequest* re=[[NSURLRequestalloc]initWithURL:[NSURLURLWithString:url]];

    

    [web loadRequest:re];

    web.autoresizingMask=UIViewAutoresizingFlexibleHeight;

    [(UIScrollView* )[[websubviews]objectAtIndex:0]setBounces:NO];

     web.scalesPageToFit =NO;

    web.delegate =self;

    [msaddSubview:web];

}

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

    CGRect frame = webView.frame;

    frame.size.height =1;

    webView.frame = frame;

    CGSize fittingSize = [webView sizeThatFits:CGSizeZero];

    frame.size = fittingSize;

    webView.frame = frame;

//  frame 根据实际需求来写

    [ms setContentSize:CGSizeMake(320,webView.frame.size.height+self.gamemodel.appTesks.count*51+30+22)];
