Hiding the UIStatusBar in iOS7

The way to hide a UIStatusBar has changed in iOS7 making the ability to hide your status bar more dynamically.

Add method in your view controller (.m).

(BOOL)prefersStatusBarHidden { return YES; }

Managing Status Bar Styles

In this short tutorial you´ll learn how to change the status bar style within your application. This is quite easy, because you really need just a few lines of code.

- (UIStatusBarStyle)preferredStatusBarStyle { return UIStatusBarStyleLightContent; }

This is the function of the type UIStatusBarStyle which allows us to change the style by returning the new style.

You can just return these styles:

return UIStatusBarStyleDefault;

Default equals black.

return UIStatusBarStyleLightContent;

Light equals white.

When the status bar style has changed within the above written code use this "call" to refresh the status bar:

[self setNeedsStatusBarAppearanceUpdate];

Please send me a mail if there is something unlogically or not understandable - hi@developing.io. 

Thank you!

UITableView tap status bar to scroll up

First we need to detect touches at status bar, and the only place (at least that i found) that we are able to detect is in AppDelegate.h.

So in the AppDelegate.h let's implement the touchesBegan:withEvent: selector and detect only tap if we are on top of status bar (mean y < 20)

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesBegan:touches withEvent:event]; CGPoint location = [[[event allTouches] anyObject] locationInView:[self window]]; if(location.y > 0 && location.y < 20) { [self touchStatusBar]; } }

Then let's implement the touchStatusBar selector in AppDelegate.h and create a notification to that selector.

- (void) touchStatusBar { [[NSNotificationCenter defaultCenter] postNotificationName:@"touchStatusBarClick" object:nil]; }

Now at your UITableViewController (or UIViewController) add and observer to this notification, best place is in viewDidLoad

- (void)viewDidLoad { [super viewDidLoad]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(statusBarHit) name:@"touchStatusBarClick" object:nil]; }

Finally scroll to top :)

- (void) statusBarHit { [[self tableView] setContentOffset:CGPointZero animated:YES]; }
