    <p>I have to say that I am a beginner in iOS development bit I think I can help you.</p> <p>In you Storyboard make a TabBarController and all the other UIViewController's. Link them to the TabBarController and add assign classes to them. In your case one of the UIViewController will be called LoginViewController.Now when your app starts the LoginViewController must be the first tab an you simply add this code to disable the tabs:</p> <pre><code>[[[[self.tabBarController tabBar]items]objectAtIndex:1]setEnabled:FALSE]; [[[[self.tabBarController tabBar]items]objectAtIndex:2]setEnabled:FALSE]; [[[[self.tabBarController tabBar]items]objectAtIndex:3]setEnabled:FALSE]; </code></pre> <p>And again you can enable them with:</p> <pre><code>[[[[self.tabBarController tabBar]items]objectAtIndex:1]setEnabled:TRUE]; [[[[self.tabBarController tabBar]items]objectAtIndex:2]setEnabled:TRUE]; [[[[self.tabBarController tabBar]items]objectAtIndex:3]setEnabled:TRUE]; </code></pre> <p>So your LoginAction function would look like this:</p> <pre><code>- (void) LoginAction { AppDelegate *passData = (AppDelegate *)[[UIApplication sharedApplication] delegate]; if ([CustomerUsername.text isEqualToString:@""] || [CustomerPassword.text isEqualToString:@""]) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"alert" message:@"Please Fill all the field" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil]; [alert show]; return; } // i will use a code from connect to DB tutorial NSString *strURL = [NSString stringWithFormat:@"http://localhost:8888/Staff.php?userName=%@&amp;password=%@",CustomerUsername.text, CustomerPassword.text]; // to execute php code NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]]; // to receive the returend value NSString *strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding]; if ([strResult isEqualToString:@"1"]) { //MainTabViewController *main = [[MainTabViewController alloc] initWithNibName:nil bundle:nil]; //UITabBarItem *tabBarItem = [[main.MainTabBar items] objectAtIndex:1]; //[tabBarItem setEnabled:TRUE]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"You are now Logged In" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil]; [alert show]; [[[[self.tabBarController tabBar]items]objectAtIndex:1]setEnabled:TRUE]; [[[[self.tabBarController tabBar]items]objectAtIndex:2]setEnabled:TRUE]; [[[[self.tabBarController tabBar]items]objectAtIndex:3]setEnabled:TRUE]; return; } else { // invalid information UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"alert" message:@"Invalide Information" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil]; [alert show]; return; } } </code></pre> <p>I hope it helped :D</p>

Querying!

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).
