Loading NSData into a UIWebView



In my web browser, I am trying to load a UIWebView with NSData obtained from an 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];





}







UIWebView loading plain HTML instead of loading the page

  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];
    }

Slow Android emulator

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?

Java Urban Myths

Along the line of C++ Urban Myths and Perl Myths : What are the Java Urban Myths? That is, the ideas and conceptions about Java that are common but have no actual roots in reality . As a Java programmer, what ideas held by your fellow Java programmers have you had to disprove so often that you've come to believe they all learned at the feet of the same drunk old story-teller? Ideally, you would express these myths in a single sentence, and include an explanation of why they are false.
