    <p>I am playing with using a sheet in my app.</p> <p>I have a little test project setup to find my way.</p> <p>I did have this code working:</p> <pre><code>- (IBAction)activateSheet:(id)sender { if (!_sheet) [NSBundle loadNibNamed:@"Sheet" owner:self]; [NSApp beginSheet:self.sheet modalForWindow:[[NSApp delegate] window] modalDelegate:self didEndSelector:NULL contextInfo:NULL]; } </code></pre> <p>but the loadNibNamed method is deprecated.</p> <p>So I substitute this:</p> <pre><code>- (IBAction)activateSheet:(id)sender { if (!_sheet) NSLog(@"1"); [[NSBundle mainBundle] loadNibNamed:@"Sheet" owner:self topLevelObjects:nil]; [NSApp beginSheet:self.sheet modalForWindow: [[NSApp delegate] window] modalDelegate:self didEndSelector:NULL contextInfo:NULL]; } </code></pre> <p>The sheet opens fine. But if I press save or cancel, I get a EXC_BAD_ACCESS exception:</p> <pre><code>int main(int argc, const char * argv[]) { return NSApplicationMain(argc, argv); } </code></pre> <p>UPDATE - This is a breeze with 10.9:</p> <pre><code>- (IBAction)activateSheet:(id)sender { if (!_sheet) [[NSBundle mainBundle] loadNibNamed:@"Sheet" owner:self topLevelObjects:nil]; [[[NSApp delegate] window] beginSheet:self.sheet completionHandler:nil]; } - (void)endSheet:(NSWindow *)sheetWindow returnCode:(NSModalResponse)returnCode { [sheetWindow orderOut:self]; } - (IBAction)save:(id)sender { [self doSave]; result = 1; [self endSheet:self.sheet returnCode:result]; } - (IBAction)cancel:(id)sender { result = 0; [self endSheet:self.sheet returnCode:result]; } </code></pre>

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.
