Correct way to load image into UIWebView from NSData object

Question

I have downloaded a gif image into an NSData object (I\'ve checked the contents of the NSData object and it\'s definitely populated). Now I want to load that image into my U

Here's an alternative method:

Save the image you downloaded into your documents folder. Then get that image's url. Then write a simple html file using that image url in the IMG SRC tag.

NSLog(@"url=%@", fileURL); // fileURL is the image url in doc folder of your app


//get the documents directory:
NSArray *paths = NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

//make a file name to write the data to using the documents directory:
NSString *fileName = [NSString stringWithFormat:@"%@/toOpen.html",
                      documentsDirectory];

//create simple html file and format the url into the IMG SRC tag
NSString *content = [NSString stringWithFormat:@"",fileURL];
//save content to the documents directory
[content writeToFile:fileName
          atomically:NO
            encoding:NSStringEncodingConversionAllowLossy
               error:nil]; // now we have a HTML file in our doc

// open the HTML file we wrote in the webview

NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"life.html"];
NSURL *url = [NSURL fileURLWithPath:filePath];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[yourWebView loadRequest:request];
