How to clear cache for my UIWebView loadHtmlString?

Question

I have built-in html in my application. I am loading loadHtmlString. At the same time, there are some image files in the folder of my documents. I want to replace my img in html with the one that is in the folder of my documents. For example, here is an example html that I have:

<div id="image"> <a href="image"> <img src="@image" class="center"> </a> </div> 

I use the following code to replace @image with the file path in my docs:

  NSString* imgFile = [NSString stringWithFormat:@"file:///%@/%@", [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/Images"],@"myimage.png"]; text = [text stringByReplacingOccurrencesOfString:@"@image" withString:imgFile]; NSURL* baseUrl = [NSURL fileURLWithPath:[[NSBundle mainBundle] resourcePath]]; [self.webView loadHTMLString:text baseURL:baseUrl]; 

(text is the html text of my html file).

It works the first time this code is called. But, for example, if I modify myimage.png and call the code again, the image is still displayed before I change it. (I check my file in the folder of my document, it has already been changed correctly).

I suspect this is due to the cache. Can anyone advise?

thanks

Note:

This is caused by the cache. I solved the problem using the following method to force UIWebView to load a new copy of the image:

 NSString* imgFile = [NSString stringWithFormat:@"file:///%@/%@?t=%d", [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/Images"],@"myimage.png",time(NULL)]; text = [text stringByReplacingOccurrencesOfString:@"@image" withString:imgFile];

I solved the problem by adding time to my url. Thus, the image will not be cached. Please refer to my questions. The question is considered closed.
