    <p>I have two pairs (.m and .h) of files. In one's interface section, I've defined a global BOOL variable. I need to get it's value in another class. How can I do it? (I can't make one class a subclass of another).</p> <p>In one file I have </p> <pre><code>@interface TabBarRotation : UITabBarController { BOOL portrait; } @end @implementation TabBarRotation - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } - (void):(UIInterfaceOrientation) interfaceOrientation { if (interfaceOrientation == UIInterfaceOrientationPortrait||interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { portrait=YES; } else if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight) { portrait=NO; } } @end </code></pre> <p>And in another's @implementation I have </p> <pre><code>- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event { if(portrait==YES) { CalcPortraitViewController *CalcPortraitController; CalcPortraitController = [[CalcPortraitViewController alloc] initWithNibName:@"CalcPortraitView" bundle:nil]; CalcPortraitController.title=@"Калькулятор"; CalcPortraitController.hidesBottomBarWhenPushed=YES; [self.navigationController pushViewController:CalcPortraitController animated:NO]; [self.navigationController setNavigationBarHidden:YES animated:NO]; } else if (portrait==NO) { CalcLandscapeViewController *CalcLandscapeController; CalcLandscapeController = [[CalcLandscapeViewController alloc] initWithNibName:@"CalcLandscapeView" bundle:nil]; CalcLandscapeController.title=@"Калькулятор"; CalcLandscapeController.hidesBottomBarWhenPushed=YES; [self.navigationController pushViewController:CalcLandscapeController animated:NO]; [self.navigationController setNavigationBarHidden:YES animated:NO]; } } </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.
