    <p>I have a simple UIViewcontroller with an xib. I present this modally and it displays correctly I have three controls on the xib that I wish to hide until the user presses the OK button and then display when app is connecting to remote server and then hiding themselves when it is finished. I have hooked them up to the IBOutlets correctly. My problem is that when the IBAction method that the OK button is hooked up to is called, setting their hidden property to NO doesn't make them visible. Here is the code:</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import "PasswordWebViewController.h" @interface ExistingUserController : UIViewController&lt;UITextFieldDelegate&gt; { UITextField *emailField; UITextField *passwordField; NSString *password; NSString *email; UIActivityIndicatorView *spinner; UIImageView *loadingImg; UILabel *loadingLabel; } @property (nonatomic, retain) IBOutlet UITextField *emailField; @property (nonatomic, retain) IBOutlet UITextField *passwordField; @property (nonatomic, retain) NSString *email; @property (nonatomic, retain) NSString *password; @property (nonatomic, retain) IBOutlet UIActivityIndicatorView *spinner; @property (nonatomic, retain) IBOutlet UILabel *loadingLabel; @property (nonatomic, retain) IBOutlet UIImageView *loadingImg; -(IBAction) onClickSend: (id) sender; -(IBAction) onClickCancel: (id) sender; -(IBAction) onClickResetPW: (id) sender; -(void)showLoadingIndicators; -(void)hideLoadingIndicators; @end </code></pre> <p>On the view did load I call the hideLoadingIndicators to set the hidden to property to YES</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; [self hideLoadingIndicators]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(stopSpinner:) name:@"StopSpinnerOnExistingUserController" object:nil]; // Do any additional setup after loading the view from its nib. } -(void)hideLoadingIndicators{ loadingLabel.hidden = YES; loadingImg.hidden = YES; [spinner stopAnimating]; } </code></pre> <p>This works fine but when I call the showLoadingIndicators in the onClickSend method where it sets hidden to NO then the controls don't show. It definitely call this method.</p> <pre><code> -(IBAction) onClickSend: (id) sender{ if ([email length] &gt;0 &amp;&amp; [password length] &gt;0){ UIApplication *myApp = [UIApplication sharedApplication]; [self showLoadingIndicators]; noIBAppDelegate*appDelegate = (noIBAppDelegate*)myApp.delegate; [appDelegate tryLoadingUserEmail:email AndPassword:password]; } else{ UIAlertView *missingAlert = [[[UIAlertView alloc] initWithTitle:@"Error" message:@"You have a blank email or password." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] autorelease]; [missingAlert show]; } } -(void)showLoadingIndicators{ self.loadingImg.hidden =NO; [self.view bringSubviewToFront:loadingImg]; self.loadingLabel.hidden = NO; [self.view bringSubviewToFront:loadingLabel]; [self.spinner startAnimating]; } </code></pre> <p>I'm probably missing something obvious here!!!</p>

    1. COHow do you know `hideLoadingIndicators` is working? Are you sure those controls aren't hidden by default?

    2. COI've checked off the hidden property for the controls in the xib and if I don't call the hideLoadingIndicators method then they are visible.

    3. COHow are you setting `email` and `password`? You mention that the method is being called. Were you referring to `showLoadingIndicators` or `onClickSend:` ?

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.
