Apple Just Released iOS Developer Beta 4 to Testers « iOS & iPhone :: Gadget Hacks
This style is used when presentation is initiated either by the existing bar button item provided by the delegate methods or by a swipe gesture within the right view. No additional API adoption is required to obtain this behavior, and all existing APIs-including that of the UIPopoverController instance provided by the delegate-will continue to work as before.
If the gesture would be insupportable in your app, setting the presentsWithGesture property of your split view controller to NO disables the gesture. However, disabling the gesture is discouraged because its use preserves a consistent user experience across all apps.
In iOS 6, changes have been introduced so that you no longer need to set a delegate and implement a method for Single-Finger and Single-Tap gesture recognizers. This makes them work well with the UIControl objects. Autorotation is changing in iOS 6. In its place, you should use the supportedInterfaceOrientationsForWindow: More responsibility is moving to the app and the app delegate. Now, iOS containers such as UINavigationController do not consult their children to determine whether they should autorotate. A view controller's supported interface orientations can change over time-even an app's supported interface orientations can change over time.
The system asks the top-most full-screen view controller typically the root view controller for its supported interface orientations whenever the device rotates or whenever a view controller is presented with the full-screen modal presentation style. Moreover, the supported orientations are retrieved only if this view controller returns YES from its shouldAutorotate method. The system intersects the view controller's supported orientations with the app's supported orientations as determined by the Info. The system determines whether an orientation is supported by intersecting the value returned by the app'ssupportedInterfaceOrientationsForWindow: The setStatusBarOrientation: However, it now works only if thesupportedInterfaceOrientations method of the top-most full-screen view controller returns 0.
This puts the responsibility of ensuring that the status bar orientation is consistent into the hands of the caller.

For compatibility, view controllers that still implement the shouldAutorotateToInterfaceOrientation: In other words, they do not fall back to using the app, app delegate, or Info. Instead, the shouldAutorotateToInterfaceOrientation: The willRotateToInterfaceOrientation: You should make sure that your apps are not using these methods to manage the layout of any subviews.
Instead, they should use the view controller'sviewWillLayoutSubviews method and adjust the layout using the view's bounds rectangle.
If you were using these methods to release data, use the didReceiveMemoryWarning method instead. You can also use this method to release references to the view controller's view if it is not being used. You would need to test that the view is not in a window before doing this. It is unsupported to set values for the shadowOffset or shadowColor properties of a UILabel object if its attributedText property contains a valid attributed string.
The setContentStretch: To achieve the same effect, use theresizableImageWithCapInsets: The resizableImageWithCapInsets: As a performance optimization, it uses stretching rather than tiling when the user would not be able to tell the difference, such as when a single column or row is being stretched. But in certain circumstances, the user might want to actually stretch some region of an image. The class now supports the customization of the animations created during rotation. The names of methods for customizing insert and delete animations have also changed, so the same hooks can be used for rotations as well as for insertions and deletions.
The class has changed some method names. Specifically, decoration views are no longer referred to by "reuse identifier" but rather by "element kind. The bottom edge of a UILabel view is now different from its baseline.
Previously, auto layout was interpreting the bottom of a UILabel to be the same as its baseline. While convenient in many cases, it caused problems if you wanted to place the top edge of one label against the bottom edge of another. In such a scenario, the bottom label would overlap the top one, and descenders from the top label could crash into ascenders from the bottom label.
Now, auto layout interprets UILayoutAttributeBottom as the bottom of the text box presuming the label is not bigger than its intrinsic content size and UILayoutAttributeBaseline as the baseline of the text. If you have already created code for laying out labels according to the bottom or center point, your text will move around a little and you will need to adjust your constraints.anavmedmored.ga

Apps with table views in their nib or storyboard files, and that were built using previous versions of iOS 6 beta, will require a clean build with beta 3 and newer. Here are some notes regarding auto layout support for UIScrollView: In general, auto layout considers the top, left, bottom, and right edges of a view to be the visible edges. That is, if you pin a view to the left edge of its superview, you're really pinning it to the minimum x-value of the superview's bounds.
Changing the bounds origin of the superview does not change the position of the view. The UIScrollView class scrolls its content by changing the origin of its bounds. To make this work with auto layout, the meaning of the top, left, bottom, and right edges within a scroll view now mean the edges of its content view. The constraints on the subviews of the scroll view must result in a size to fill, which is then interpreted as the content size of the scroll view.
This should not be confused with the intrinsicContentSize method used for auto layout.

To size the scroll view's frame with auto layout, constraints must either be explicit regarding the width and height of the scroll view, or the edges of the scroll view must be tied to views outside of its subtree. Note that you can make a subview of the scroll view appear to float not scroll over the other scrolling content by creating constraints between the view and a view outside the scroll view's subtree, such as the scroll view's superview.
Here are some examples of how to configure the scroll view: Mixed approach: Position and size your scroll view with constraints external to the scroll view-that is, thetranslatesAutoresizingMaskIntoConstraints property is set to NO. Create a plain UIView content view for your scroll view that will be the size that you want your content to have. Make it a subview of the scroll view but let it continue to translate the autoresizing mask into constraints: CGMakeSize contentWidth,contentHeight ]; Create the views you want to put inside the content view and configure their constraints so as to position them within the content view.
Alternatively, you can create a view subtree to go in the scroll view, set up your constraints, and call the systemLayoutSizeFittingSize: For users who are enrolled in the iOS 11 beta testing programs, iOS If you are actively using the iOS 12 beta now then iOS Beta updates to watchOS and tvOS are also available via their respective Settings apps on devices enrolled in those beta testing programs as well.
