Question

In my web browser, I am trying to load a UIWebView with NSData obtained from a NSURLConnection. When I try to load it into the UIWebView, instead of the site, it comes up with the HTML plain text.

Here is my code:

in viewDidLoad:

NSURLRequest *request = [NSURLRequest requestWithURL: [NSURL URLWithString:@"http://www.msn.com"]];
[NSURLConnection connectionWithRequest: request delegate:self];

later in the code:

 -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
  {
     webdata = [NSMutableData dataWithData: data];
  }

 -(void)connectionDidFinishLoading:(NSURLConnection *)connection
  {
    [webview loadData:webdata MIMEType: @"text/html" textEncodingName: @"UTF-8" baseURL:nil];
  }

Answer 1

You are not appending data that you are receiving. Use this piece of code

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
    if (webdata == nil) {
        webdata = [[NSMutableData alloc] init];
    }
    [webdata appendData:data];
}

This method might be called once or more times depending upon your data length. So instead of assigning new data to your ivar, append your data to it so that you have the full response not the last packet of data received.

Or use like this.

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{
        webdata = [[NSMutableData alloc] init];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
    [webdata appendData:data];
}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection{
    [mWebView loadData:webdata MIMEType: @"text/html" textEncodingName: @"UTF-8" baseURL:nil];
}
