Η Apple μπορεί να ανακοίνωσε το iOS 9 στο WWDC χθες αλλά αυτό δεν σημαίνει πως ξέχασε την iOS 8.4 beta. Η 4η έκδοση αυτής της beta είναι από σήμερα διαθέσιμη στους προγραμματιστές της λίγο πριν κυκλοφορήσει στο ευρύ κοινό στο τέλος αυτού του μήνα.
Η νέα beta έχει build number 12H4125a, και είναι διαθέσιμη για λήψη over-the-air για αυτούς που ήδη έχουν εγκατεστημένη την iOS 8.4 beta 3 στην συσκευή τους — εναλλακτικά κάποιος μπορεί να την κατεβάσει από το Apple Developer portal.
Η iOS 8.4 θα έχει ως μεγάλο της χαρακτηριστικό το λανσάρισμα του Apple Music. Μια από τις μεγαλύτερες αλλαγές της εφαρμογής μουσική της Apple.
Διαβάστε παρακάτω το συνοδευτικό κείμενο που έδωσε η Apple για την beta 4:
App Extensions
Notes
- App extensions need an arm64 slice to run on 64-bit devices. If you try to run the armv7 slice on a 64-bit device it won’t work.
- Apps need to have an arm64 slice if the bundle contains a framework that both the app and the app extension link against.
Music
Fixed in Beta 4
- Using Siri to control iTunes Radio does not work in this beta.
Known Issues
- Home Sharing and Genius Mixes are not currently available.
- AirPlay streaming may not work.
- It’s not possible to start a station from a song or artist.
- Station sharing for iTunes Radio is not available.
- The iTunes Radio tab may unexpectedly appear within Search, even if iTunes Radio is not available in your country.
- The Music app may forget its place when you go to the Home screen and come back.
- Ads in iTunes Radio may display on top of Up Next.
- The downloaded icon is not displayed in Songs view on the iPad when you select “Make Available Offline.”
Siri
Known Issue
- “Play <Song> Siri” requests from a watch are failing for a few days when the iPhone has a new install of iOS 8.4. Workaround: Request playback of Artists or Albums instead of a specific song.
UIKit
Note
When linking against iOS 8.3 or later, any code that relies on layout information (such as the frame) of a UIButton subview when the button is not in the window hierarchy will need to send layoutIfNeeded to the button before retrieving layout information (such as button.titleLabel.frame) to ensure that the layout values are up to date.
Videos
Known Issues
- Content stored in iCloud may not appear in your library after signing in.
WatchKit
Note
A bug where continuous background location updates fail to update has been resolved. If your Watch app relies on continuous background location updates to function, it is recommended that you update your WatchKit extension deployment target to iOS 8.3 and submit your app with Xcode 6.3.
Known Issues
- Creating an animated image using the UIImage method animatedImageWithImages:duration:and then playing the animation using startAnimating ignores the duration and plays back as fast as possible. Workaround: Use startAnimatingWithImagesInRange:duration:repeatCount:instead.
- The appearance of default notifications on a Watch differs slightly from the appearance of default notifications in the Simulator.
