Body
I'm trying to do something like this: <a href="http://www.pushplay.net/2009/05/framework-for-having-multiple-views-in-an-iphone-app/" rel="nofollow">http://www.pushplay.net/2009/05/framework-for-having-multiple-views-in-an-iphone-app/</a> So far I've got this structure: appDelegate -> rootViewController -> welcomeViewController I've a method (doSomething) in my delegate, which is called by an IBAction in welcomeViewController. It works, I can do an NSlog in doSomething and it shows the method is being called within the delegate. The problem is when I run a command like [rootViewController loadNewView] in my doSomething method (in the delegate), it does nothing. It doesn't error, it just does nothing. I've been reading and seen protocols and notifications are suggested, but I'd like to know why this method using the delegate doesn't work and if there is any way to fix it. SurveyClientAppDelegate.h <pre><code>@interface SurveyClientAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; RootViewController *rootViewController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet RootViewController *rootViewController; -(void)doSomething; @end </code></pre> SurveyClientAppDelegate.m <pre><code>- (void)doSomething { NSLog(@"Attempt: rootViewController loadLocationList"); [rootViewController loadLocationList]; } </code></pre> RootViewController.h <pre><code>@interface RootViewController : UIViewController { WelcomeViewController *welcomeView; } @property (nonatomic, retain) WelcomeViewController *welcomeView; @property (nonatomic, retain) SurveyListViewController *surveyList; -(void)loadLocationList; </code></pre> RootViewController.m <pre><code>- (void)loadLocationList { NSLog(@"RootViewController: loadLocationList"); } </code></pre> WelcomeViewController.h <pre><code>@interface WelcomeViewController : UIViewController -(IBAction)viewList:(id)sender; -(void)loadLocationList; </code></pre> WelcomeViewController.m <pre><code>- (void)viewList:(id)sender { SurveyClientAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; [appDelegate doSomething]; } </code></pre>

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.
