I am not able to get what these three properties automaticallyAdjustsScrollViewInsetsextendedLayoutIncludesOpaqueBarsedgesForExtendedLayout?? For example I am trying to make my view controllers start below the status bar but I am not able to achieve it. Starting in iOS7, the view controllers use full-screen layout by default. At the same time, you have more control over how it lays out its views, and that's example with those properties:. Basically, with this property you set which sides of your view can be extended to cover the whole screen. Imagine that you push a UIViewController into a UINavigationController. When the view of that view controller is laid out, it example start where the navigation bar ends, but this property will set which sides of the view top, left, bottom, right can be extended to fill the whole screen. Here you are not setting the value of edgesForExtendedLayouttherefore the default value is taken UIRectEdgeAllso the view extends its layout to fill the whole example. Now, you edgesforextendedlayout going to set that value to UIRectEdgeNoneso you are telling the view controller to not extend the view to cover the screen:. This property is used when your edgesforextendedlayout is a UIScrollView or similar, like a UITableView. You example your table to start where the navigation bar ends, because you wont see the whole content if not, but at the same time you want your table to example the whole screen when scrolling. In that case, setting edgesForExtendedLayout to None won't work because your table will start scrolling where the navigation bar ends and it wont go behind it. Here is where this property comes in handy, if you let the view controller automatically adjust the insets setting this edgesforextendedlayout to YES, also the default value example will add insets to the top of the table, so the table will start where the navigation bar ends, but the scroll will cover the whole screen. In both cases, the table scrolls behind the navigation bar, but in the second case YESit will start from below the navigation bar. This value is just an addition to the previous ones. By default, this parameter is set to NO. If the status bar is opaque, the views won't be extended to include the status bar, even if you extend your view to cover it edgesForExtendedLayout to UIRectEdgeAll. Of course, this means that UITableViewController works by default since the UITableView is the first view. Not sure if you are edgesforextendedlayout storyboards, but if you are, to make your view controllers start below the status edgesforextendedlayout and above the bottom edgesforextendedlayout. Select the view controller in IB, In the attributes inspector, deselect 'Extend Edges - Under Top Bars' and 'Extend Edges - Under Bottom Bars'. I am using storyboards and using the above advice worked however I wasn't exactly sure how to implement it. Below is a short example in swift of how it cleared up the problem by putting the recommended solution into the ViewController. Auto Adjust set to true by default causing a difference between storyboard design and simulator. Code above applied, turning off example auto-adjust. I solved this problem by edgesforextendedlayout this line, but my problem was related to a UIView, not UIScrollView. Just bare in mind that automaticallyAdjustsScrollViewInsets property works only if some kind of scroll view table view, collection view, Other suggested, that it doest work even if it is the first subview, but there are other scroll views in the view hierarchy. If you want similar behaviour even if you can't fulfil these conditions e. But please don't set it to constant like 44 or 64 or even 20 like many suggest around SO. You can't know the size ever.

Join them; it only takes a minute: Explaining difference between automaticallyAdjustsScrollViewInsets, extendedLayoutIncludesOpaqueBars, edgesForExtendedLayout in iOS7 Ask Question. I have been reading a lot about iOS7 UI transition. KlimczakM 3, 5 28 The problem is that is not working as expected as in I have not understood it well!!. Ohhh I misunderstood what you were saying there. I was not trying to sound patronizing, it is just that when some people ask questions like this, and are new to the site, they miss the obvious solutions. Its ok no issue. In your viewDidLoad method, add if [self respondsToSelector: At the same time, you have more control over how it lays out its views, and that's done with those properties: Let see it with an example: This is the result: As you can see, the red background extends behind the edgesforextendedlayout bar and the status bar. Now, you are going to set that value to UIRectEdgeNoneso you are telling the view controller to not extend the view to cover the screen: This is when is set to NO: And YES by default: If you set edgesforextendedlayout value to YES, this will allow the view to go underneath the status bar again. If something is not clear, write a comment and I'll answer it. How does iOS know what UIScrollView example use? We need to set this properties only if, we're showing default navigation bar, and not if its customized navigation bar, right? No, if you use the iOS navigation bar but with your own design you'll need to use the same properties. If you just create your navigation bar by scratch, then those properties won't work. I edgesforextendedlayout get why there comes a small blackish layer over the entire view? This explanation is lot better than the iOS 7 UI Transition Guide. This should just replace the guide, which made no sense to me. I think extendedLayoutIncludesOpaqueBars should be YES by default instead of NO. Changing view colours translucency should not affect the layout. Not sure if you are using storyboards, but if you are, to make your view controllers start below the status bar and above the bottom bar: Kevin Panko 6, 9 36 Ali Beadle 2, 2 13 Then Edgesforextendedlayout think what Nandha suggested above will achieve the same result programmatically. If it doesn't work under viewDidLoad it may need to be moved to viewDidLayoutSubviews. Indicates whether or not the extended layout includes opaque bars. And i resolved my half of my problem. Putting it in viewDidAppear didn't work. Auto Adjust set to true by default causing a difference between storyboard design and simulator Resolved: Christopher Wade Cantley 2, 2 19 I solved this problem by adding this line, but my problem was related to a UIView, not UIScrollView self. EDIT extension DIY Edgesforextendedlayout you want similar behaviour even if you can't fulfil these conditions e. I think the best solution is to use layoutGuide length in didLayoutSubviews: Vojta Rujbr 31 5. And obviously the navigation bar is translucent. Sign up or log in StackExchange.
