    <p><strong>Update 22nd April:</strong></p> <p><em>Problem solved: Turned out that the API required OAUTH to work... which explained why it would load correctly in the browser (I was already signed in) and not in other applications such as the JSON validator or my own App.</em></p> <p>I'm trying to write a class which will fetch and parse a JSON file in Xcode 4.3.2 on Lion. I've only been coding for a few weeks so sorry if this is a bit of a stupid question! The code seems to work fine except for the fact that only the first 20 entries in the JSON file show up (there should be 200). Any idea why this might be?</p> <pre><code> - (void) initJSON { NSString *urlstri = [[NSString alloc] initWithFormat:@"http://api.t.sina.com.cn/statuses/followers.json?source=?????&amp;count=200&amp;screen_name=%@", userName]; NSURL *newURL = [[NSURL alloc] initWithString:urlstri]; NSURLRequest *request = [NSURLRequest requestWithURL:newURL]; [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) { [self performSelectorOnMainThread:@selector(fetchedData:) withObject:data waitUntilDone:NO]; } ];} - (void) fetchedData:(NSData *)responseData { //parse out the json data NSError* error; NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseData //1 options:kNilOptions error:&amp;error]; NSArray* newestFollower = [json objectForKey:@"users"]; //2 fnumber = 0; mnumber = 0; int arraySize = [newestFollower count]; NSLog(@"%i",arraySize); for (i=0; i&lt;arraySize; ++i) { NSDictionary* userProfile = [newestFollower objectAtIndex: i]; NSString* userGender = [userProfile objectForKey:@"gender"]; //NSLog(@"%@", userGender); if([userGender isEqualToString:@"m"]){ //NSLog (@"man"); ++mnumber; } if([userGender isEqualToString:@"f"]){ //NSLog(@"notman"); ++fnumber;} } mOutput = [NSNumber numberWithInt:(mnumber)]; fObj = [NSString stringWithFormat:@"%i", fnumber]; mObj = [NSString stringWithFormat:@"%i", mnumber]; NSLog (@"Boys:%@", mObj); NSLog (@"Girls:%@", fObj); </code></pre>

    1. COHave you tried copying your `urlStri` and pasting into a browser to verify that the server is indeed returning 200 items like you expect? When you NSLog the `arraySize` in your code is it 20 or 200?

    2. COThanks for your quick reply. When I copy the URL into the browser it returns all 200 items, yet the arraySize is only 20. If I NSLog the json NSDictionary I also get only 20 items..

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
