    <p>How can I make sure that a query is finished (whether successful or not) before performing another task.</p> <p>Here is my viewDidLoad...this line of code at the end</p> <pre><code> NSLog(@"tweets Array %@",self.tweetsArray); </code></pre> <p>Is showing that tweetsArray is empty</p> <p>Yet the same line of code in the block above it shows the Array to be full. </p> <p>The Output also shows the last NSLog before the first. </p> <p>My tableView is blank on the simulator because it is calling the UITableView methods before it has finished running query.</p> <p>Any help on this would be great.</p> <p>Thanks in Advance... Nick</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. self.tableView.dataSource = self; self.tableView.delegate = self; self.selectString = self.gamesString; PFQuery *query = [PFQuery queryWithClassName:@"Parse_Storyw"]; [query whereKey:@"searchName" equalTo:self.gamesString]; [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { if (!error) { // Do something with the found objects for (PFObject *object in objects) { NSLog(@"%@", object.objectId); PFQuery *query = [PFQuery queryWithClassName:@"Parse_Story"]; [query getObjectInBackgroundWithId:object.objectId block:^(PFObject *content, NSError *error) { PFFile *file = [content objectForKey:@"levels"]; [file saveInBackground]; [file getDataInBackgroundWithBlock:^(NSData *data, NSError *error) { NSString *string = [[NSString alloc] initWithData: data encoding: NSMacOSRomanStringEncoding]; self.tweetsArray = [[NSArray alloc] initWithArray:[string componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]]]; NSLog(@"tweets Array %@",self.tweetsArray); }]; }]; } } else { // Log details of the failure NSLog(@"Error: %@ %@", error, [error userInfo]); } }]; self.title = self.selectString; NSLog(@"tweets Array %@",self.tweetsArray); } </code></pre>

Querying!

 
Guidance
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.

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