Body
I am having problems updating a view when a message from another class is sent to a <code>ViewController</code>. Basically I have an application with a single window where different custom views will be swapped out for another. I have an <code>AppController</code> Class that manages this and works fine: <pre><code>@interface AppController : NSObject @property (weak) IBOutlet NSView *ourView; @property (strong) NSViewController *ourViewController; - (IBAction)changeView:(id)sender; - (IBAction)start:(id)sender; - (void)changeViewContoller:(NSInteger)tag; @end </code></pre> When a new view is swapped out for another, the <code>ourViewController</code> property will be updated to point to that view's controller class. Every view controller class will have a method all named the same thing, for example "action". This method is supposed to change something on a view. So the "start" method in <code>AppController</code> class will then call the "action" method on the <code>ourViewController</code> property. To do this I used the <code>objc_msgSend()</code> method: <pre><code>objc_msgSend(self.ourViewController, action); </code></pre> Here's the View Controller class definition: <pre><code>@interface CountdownViewController : NSViewController @property (weak) IBOutlet NSTextField *label; - (IBAction)changeLabel:(id)sender; - (void)start; @end </code></pre> I placed an <code>NSLog()</code> in the "action" method for each <code>ViewController</code>, to see if it was working, and it does, however the "action" method is also supposed to change a label's string value, but it does not. If anyone knows why the view is not being updated, that would be extremely helpful. Thanks!

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.
