iOS 11 beta 4 a fost lansat pentru iPhone si iPad in aceasta seara, compania Apple oferind actualizarea pentru toti dezvoltatorii de aplicatii pentru platforma iOS. iOS 11 beta 4 poate fi instalat de catre acestia, sau oricine are o versiune anterioara, folosind sistemul Software Update, Actualizare Software, chiar din acest moment, insa trebuie sa aveti terminalele incarcate la macar 50% din baterie pentru a o face, ori sa le conectati la o sursa de energie.
iOS 11 beta 4 are cu siguranta o serie de schimbari interesante implementate pentru iPhone, iPad si iPod Touch, iar unele dintre ele vor fi cu siguranta vizibile. iOS 11 beta 4 va avea si multe imbunatatiri ale functionalitatii, plus rezolvarea unora dintre problemele de functionare raportate pana acum, acestea existand in numar foarte mare, dar asta este normal pentru o versiune beta a iOS oferita de catre Apple.
iOS 11 beta 4 NU este versiunea public beta pe care compania Apple o ofera separat pentru utilizatorii iPhone si iPad, asa ca pentru aceea veti mai avea de asteptat, cel mai probabil pana maine. In general, compania Apple lanseaza versiunile public beta la aproximativ 1/3 zile in urma versiunii standard, deci daca iOS 11 beta 4 a fost lansat azi, maine sau poimaine ar trebui sa puteti instala si versiunea public beta.
iOS 11 beta 4 aduce unele schimbari cu siguranta, chiar daca Apple nu le detaliaza, iar pe toate le veti gasi in acest articol de indata ce vor fi descoperite. Separat de iOS 11 beta 4, compania Apple a mai lansat watchOS 4 beta 4, macOS 10.12 beta 4 si tvOS 11 beta 4.

(32272318)
- Siri may use information from previous requests when completing the current request, even if Siri was closed between the requests. (33148434)Workaround: To begin a new request use the “Start over” Siri command.
- Using Siri to correct the spelling of a transcribed request may result in an error.Workaround: Tap the misspelled word and correct it using the on-screen keyboard.
- Weather snippets currently show a sash icon from the iOS Weather app. The snippet should show the icon for The Weather Channel. It is also missing an attribution that opens The Weather Channel app. (31429437)
- Users may encounter disambiguation issues while using Siri for Phone and Messages. (32477407)
- Using Siri to disambiguate between multiple phone numbers for a contact sometimes does not work. (32591639)Workaround: Tap a selection in the UI. SiriKitResolved Issues
- Siri no longer loops when using SiriKit Notes queries to mark a reminder. (32398834)
- When a user verbally tries to disambiguate between two or more SiriKit apps in a disambiguation list, Siri now prompts for more details before opening an app. (32188589)
- SiriKit testing now works in Simulator. (32721342)
- If the user does not mention the app name in the initial utterance, tapping the app in the disambiguation no longer launches the app instead of other possible Siri actions. (32361047)
- INImage objects constructed with URLs or image names now display correctly in the Siri UI. (31585381)Touch IDNew Issues• Touch ID does not work correctly with LocalAuthentication.framework in the iOS 11 Simulator Runtime. (33355624)Workaround: Test Touch ID functionality on-device or with an older runtime. UIKitResolved Issues
- SettingthedelaysContentTouchespropertyofUITableViewtofalsenowworks correctly and results in cells highlighting immediately on a touchdown event. (27102830)
- ImportingadocumentusingUIDocumentPickerViewControllernowreturnsa copy of the document. (32358695)
- In drag and drop, move operations are supported only when the drag and the drop both happen within the same app. Starting in beta 2, the value of UIDropSession.allowsMoveOperation is set to false. (32416557)
- TheviewargumentofthelocationInView:methodofUIDragSessionand UIDropSession is no longer nullable. The declaration of the method has changed to location(in view: UIView). (31714683)Known Issues
- UIDocumentBrowserViewController does not show UIDocumentPickerExtensionViewController app extensions in the list of sources. While these will be re enabled in a future beta, consider using an NSFileProviderExtension instead, as they are integrated in UIDocumentBrowserViewController instead of being presented in a separate sheet. (31975976)
- SettingthetextContentTypetousernameorpasswordforUITextFieldinthe previewProvider property of UIDragItem is not fully implemented. During the drag session, each change to the previewProvider causes an immediate update, regardless of which app changed it. In addition, clearing the previewProvider does not cause the preview to go back to its non-overridden state. (30385458)
- SettingthepreviewProviderpropertyofUIDragItemimmediatelyafterthedrag item is created has no effect. (32284908)Workarounds:Implement dragInteraction:previewForLiftingItem:session: in your drag interaction’s delegate to change the lift preview. The preview carries over to the drag session.Change the preview during the drag session by setting previewProvider after the delegate’s sessionWillBegin is called. If you are using UITableView or UICollectionView, there is no direct equivalent of that method, so you may use a delay instead.
- ThecanLoadObjectsOfClasses:methodofUIDragDropSessionwillberemoved in a later seed. Use canLoadObjectOfClass: instead. (32242367)
- When dragging more than five items, the drop/cancel animation uses a default animation. The system calls the dropping/canceling preview calls for the first five of these items, even though they are not used. In a later beta, the system will not make these calls, and instead provides an additional API for animating alongside items for which a custom animation cannot be applied. (32299785)
- DonotusetheclassUIURLDragPreviewViewbecausewillberemovedinalaterbeta. To make drag previews of URLs, use UIDragPreview and UITargetedDragPreview. (32306613)
- Table views in Interface Builder documents compiled with Xcode 9.0 may have fixed heights for rows, section headers, and section footers, and may not self-size by default. (32188814)
Workaround: Set the table view rowHeight, sectionHeaderHeight, or sectionFooterHeight to UITableViewAutomaticDimension after the table view has been instantiated.
- UITableView has a new system gesture for quickly selecting rows. A two-finger tap on table views that support multiple selection sets the table view to editing, if it is not already, and selects the tapped row. Unlike a single-finger tap, which toggles selection, the two- finger tap always selects the tapped row and has no effect if the row is already selected. This new gesture is enabled only in apps built for iOS 11. (29127664)
- UITableView has a new property, separatorInsetReference, that changes how a custom value set in the separatorInset property is interpreted. By default, the value is .fromCellEdges, which means that custom separatorInset values are always interpreted as an inset from the edges of the cell, even in cases where table view would normally use larger automatic insets for the separator, such as a very wide table view when the cellLayoutMarginsFollowReadableWidth property is true.Set the separatorInsetReference to .fromAutomaticInsets to use the separatorInset as a fixed distance from the automatic inset that a table view would normally use.Note that you can always use UITableViewAutomaticDimension for any edge of the separatorInset that you set, to receive the automatic inset on that edge. (31000402)
- Table views now use estimated heights by default, which also means that cells and section header/footer views now self-size by default. The default value of the estimatedRowHeight, estimatedSectionHeaderHeight, and estimatedSectionFooterHeight properties is now UITableViewAutomaticDimension, which means the table view selects an estimated height to use. You should still provide a more accurate estimate for each property if possible, which is your best guess of the average value of the actual heights. If you have existing table view code that behaves differently when you build your app with the iOS 11 SDK, and you don’t want to adopt self-sizing, you can restore the previous behavior by disabling estimated heights by setting a value of zero for each estimated height property.

- AddingcustomsubviewsdirectlytoUITableViewisnotsupportedandmightbreakina future iOS release. (29094519)
- The behavior of the delete swipe action has been changed.When implementing commitEditingStyle: to delete a swiped row, delete the row in the data source and call deleteRowsAtIndexPaths: on the table view to show the swipe delete animation. Not calling deleteRowsAtIndexPaths inside of this method results in the swiped row resetting to its resting position. Do not display a confirmation dialog in the implementation of this method, and support undo to allow canceling a deletion. To show a confirmation dialog, use a UIContextualAction instead (described next).
When implementing a destructive UIContextualAction, delete the row in the data source and call the completion handler with true. Do not call deleteRowsAtIndexPaths: in this case. If the deletion fails, call the completion false to cancel the deletion. Although it should generally be avoided, you can show a confirmation dialog to confirm the deletion, and then call the completion handler with true if the user confirms (after deleting the row from its data source), or with false if the user cancels. It is also advised to disable performsFirstActionWithFullSwipe on the UISwipeActionsConfiguration in this case. Note that the completion handler must be called in all cases. (31588888)
- When the user selects one of the Accessibility Larger Text content sizes as their preferred content size, UITableViewCell uses a new default layout that is optimized for the larger sizes. The numberOfLines property of UITableViewCell labels (both textLabel and detailTextLabel) changes to 0 (unlimited) by default when the Accessibility content sizes are in use. You may override this by explicitly setting the numberOfLines property. The standard image view and accessory views are aligned with the first line of text in the cell, and cell text wraps around the image in order to maximize the amount of text displayed per line. For the Value1, Value2, and Subtitle styles, the detailTextLabel is arranged underneath the standard textLabel. For UISwitch accessory views, the switch is located below the labels and aligned with the leading edge of the text. Because of these changes, which increase the height of the cell content at Accessibility content sizes, it’s important to use self-sizing cells to ensure that the row height increases as necessary, and to avoid using a fixed row height for all content sizes.

- TheimageNamed:inBundle:compatibleWithTraitCollection:classmethod of UIImage now properly infers the UIDisplayGamut trait if it is not explicitly provided.If you are deploying to earlier versions of iOS, to provide the UIDisplayGamut trait in the trait collection, you pass to imageNamed:inBundle:compatibleWithTraitCollection:. You can obtain the correct value of this trait from the window or view that will display the image. Failing to provide the value can result in images failing to load on devices with P3 displays if the sRGB renditions of those images had been thinned out of the asset catalog. (29915518)
- UINavigationItem.searchController appears only for view controllers that use a UIScrollView. (32511772)Workaround: Set UINavigationItem.hidesSearchBarWhenScrolling to false.
- By default, UIKit logging occurs only when unsatisfiable constraints are detected. Use the
launch argument to add an assertion for early detection of the problem. The launch argument works in iOS 11 and later. (28123998)
- AUIViewthatmakesvisualchangesbothbyoverridingdrawRect:andbysettingthe layer contents may result in visual artifacts or other errors in iOS 11. Apps should use only one of the methods to make visual changes to a view. (31350188)
- Vision now supports other Core ML feature vectors in addition to classifiers. iOS 11 beta 2 and earlier worked only with classifier models. (32944774)
- TheRectangleTrackerAPIshouldshouldnolongerstoprespondingunexpectedly. (32332200)
- The Vision API is now available from the macOS 10.13 and iOS 11 SDKs even if DEPLOYMENT_TARGET is set to a version earlier than the current OS.Known Issues• Facial landmarks identified by the Vision framework may flicker in temporal use cases such as video. (32406440)Deprecations
• The type of the orientation parameter in Vision framework calls has changed from an Int32 to an CGImagePropertyOrientation enum found in the ImageIO framework.
Important: Update your code with the new type to avoid compilation warnings or errors related to the change.
- In the Watch app, changes to Mail > Include Mail are now saved. (32553544)
- On an Apple Watch running a version of watchOS earlier than 4, location activity now correctly sets the location arrow in the status bar or in Settings. (31496053)
- watchOS email alerts now use the configured settings. (32332614)Known Issues• Pairing an iPhone running a beta of iOS 11 and an Apple Watch running a version of watchOS earlier than 4 may fail. (32587160)Workaround: Attempt to pair the Apple Watch again.
