    <p>I'm getting an HTML file as NSData and need to extract some parts of it. For that I need to convert it to NSString with UTF8 encoding. The thing is that this conversion fails, probably because the NSData contains bytes that are invalid for UTF8. I have tried to get the byte array of the data and go over it, but each time I come across non ASCII character (hebrew letters for example) I get jibrish.</p> <p>Help will be appreciated.</p> <p>UPDATE:</p> <p>To Gordon - the NSData generated like that:</p> <pre><code> NSData *theData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&amp;theResponse error:&amp;theError]; </code></pre> <p>When I say that the conversion fails I mean that </p> <pre><code>[[NSString alloc] initWithData:temp encoding:NSUTF8StringEncoding] </code></pre> <p>returns nil</p> <p>To Ed - Here is my code (I got the Byte array from NSData, found what I need, and constructed another Byte array from that - turned it to NSData and then attempted to convert it to NSString... sounds kinda complicated...)</p> <pre><code>-(NSString *)UTF8StringFromData:(NSData *)theData{ Byte *arr = [theData bytes]; NSUInteger begin1 = [self findIndexOf:@"&lt;li&gt;" bArr:arr size:[theData length]]+4; NSUInteger end1 = [self findIndexOf:@"&lt;/li&gt;&lt;/ol&gt;" bArr:arr size:[theData length]]; Byte *arr1 = (Byte *)malloc(sizeof(Byte)*((end1-begin1+1))); NSLog(@"%d %d",begin1, end1); int j = 0; for (int i = begin1; i &lt; end1; i++){ arr1[j] = arr[i]; j++; } arr1[j]='\0'; NSData *temp = [NSData dataWithBytes:arr1 length:j]; return [[NSString alloc] initWithData:temp encoding:NSUTF8StringEncoding]; </code></pre> <p>}</p>

    1. COHow is this NSData being generated? Right now it sounds like the problem is that you have mixed encodings from the source. Also, when you say that the conversion fails, what do you mean exactly? Do you get an error, garbage output, something else?

    2. COIt sounds like you're doing it right. Post the code so it can be verified.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
