我的iframe不能用于UIWebView [英] My iframe does not work with a UIWebView

问题描述

我在任何地方都测试过我的 iframe ，它运行得非常好，但是在 iOS > Objective-C ，它不能在 UIWebView 上工作，这里是我的代码，有人可以帮我吗？谢谢

  self.webView.scrollView.scrollEnabled = NO; 
 
 NSString * Str = [NSString stringWithFormat：@< iframe frameborder = \0 \width = \359 \height = \200 \src = \// www.dailymotion.com/embed/video/%@\allowfullscreen>< / iframe>，identifier]; 
 
 [_webView loadHTMLString：Str baseURL：nil]; 
  

我的iframe：

 < iframe frameborder =0width =359height =200src =// www.dailymotion.com/embed/video/x5b4cfzallowfullscreen>< / iframe> 
  

解决方案

您需要将此密钥添加到您的info.plist

 < key> NSAppTransportSecurity< / key> 
< dict> 
< key> NSAllowsArbitraryLoads< / key> 
< true /> 
< / dict> 
  

我发现的主要问题是基本Url，在您的代码中缺失，因此添加此代码使用基本URL @http://www.dailymotion.com，并更改了从 loadHTMLString to loadData 这对我来说总是有更好的结果



已编辑：改进了代码以处理宽度WebView作为@Mozahler建议错误

  self.webView.scrollView.scrollEnabled = NO; 
 
 NSString * identifierTest = @x5b4cfz; 
 
 NSString * Str = [NSString stringWithFormat：@< iframe frameborder = \0 \width = \％@ \height = \\200 \src = \// www.dailymotion.com/embed/video/%@\allowfullscreen>< / iframe>，[NSString stringWithFormat：@％f，self.webView.frame.size.width  - 10]，identifierTest]; 
 
 NSLog（[NSString stringWithFormat：@％f，self.webView.frame.size.width  -  10]）; 
 
 [_webView loadData：[str dataUsingEncoding：NSUTF8StringEncoding] 
 MIMEType：@text / htmltextEncodingName：@UTF-8
aseURL：[[NSURL alloc] initWithString ：@ http://www.dailymotion.com]]; 
  

有效，如您所见



希望这会有所帮助

I have tested my iframe everywhere and it works very well, but on iOS in Objective-C, it does not work on UIWebView, here is my code, can someone help me? Thanks

self.webView.scrollView.scrollEnabled = NO;

NSString *Str = [NSString stringWithFormat:@"<iframe frameborder=\"0\" width=\"359\" height=\"200\" src=\"//www.dailymotion.com/embed/video/%@\" allowfullscreen></iframe>", identifier];

[_webView loadHTMLString:Str baseURL:nil];

My iframe :

<iframe frameborder="0" width="359" height="200" src="//www.dailymotion.com/embed/video/x5b4cfz" allowfullscreen></iframe>

解决方案

You need to add this Key to your info.plist

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

The main problem that I found is the base Url, was missing in your code, so add this code with base url @"http://www.dailymotion.com", and changed the way to load html from loadHTMLString to loadData this always have better results for me

Edited: Improved your code to handle width of WebView as @Mozahler suggest was wrong

self.webView.scrollView.scrollEnabled = NO;

NSString *identifierTest = @"x5b4cfz";

NSString *Str = [NSString stringWithFormat:@"<iframe frameborder=\"0\" width=\"%@\" height=\"200\" src=\"//www.dailymotion.com/embed/video/%@\" allowfullscreen></iframe>",[NSString stringWithFormat:@"%f",self.webView.frame.size.width - 10], identifierTest];

NSLog([NSString stringWithFormat:@"%f",self.webView.frame.size.width - 10]);

[_webView loadData:[Str dataUsingEncoding:NSUTF8StringEncoding]
          MIMEType:@"text/html" textEncodingName:@"UTF-8"
           baseURL:[[NSURL alloc] initWithString:@"http://www.dailymotion.com"]];

it works, as you can see

Hope this helps
