As I said above, iOS 7.1 beta 3 can be downloaded via OTA for users with a developer account and a compatible iOS device, including the iPhone 4, iPhone 4S, iPhone 5, iPhone 5c, iPhone 5s, iPad 2, iPad (third and fourth generations), iPad Air, iPad mini and iPhone mini with Retina display. It also should be made available for download on Apple’s developer website shortly.
Notes and Known Issues
The following issues relate to using iOS SDK 7.1 beta 3 to develop code.
Bluetooth
Known Issue
32-bit apps running on a 64-bit device cannot attach to BTServer.
CFNetwork
Notes
A compatibility behavior has been added to address an issue where some web servers would send the wrong Content-Length value for “Content-Encoding: gzip†content. Previously, NSURLConnection and NSURLSession would send a “network connection was lost†/ NSURLErrorNetworkConnectionLost (-1005) error in this situation.
The compatibility behavior applies only if the Content-Length value exactly matches the expanded gzip’d content. It won’t apply for “off by 1†or similar miscounting.
iCloud
Fixed in iOS 7.1 beta 3
Creating a new iCloud account during setup assistant, should no longer give you an error when you enable iCloud Keychain.
Messages
Known Issue
Messages sometimes indicates iMessage send failure immediately after sending.
Workaround:Tap the error icon to re-send the message.
Music App
Fixed in iOS 7.1 beta 3
Audiobooks now play as expected.
Safari
Notes
A property, minimal-ui, has been added for the viewport meta tag key that allows minimizing the top and bottom bars on the iPhone as the page loads. While on a page using minimal-ui, tapping the top bar brings the bars back. Tapping back in the content dismisses them again.
For example, use <meta name=â€viewport†content=â€width=1024, minimal-uiâ€>.
UIKit
Known IssuesIf a UITextField or a UILabel that is baseline aligned with constraints has attributes that change after the constraints have been added, the layout may be incorrect. The exception to this is -setFont: on UILabel, which should work as expected.Workaround: Avoid making changes in UITextField or UILabel after adding baseline-alignment constraints. If you must make changes, you should remove the constraints and then reapply them afterward. Note that this is a performance hit, so don’t do it unless it is necessary.
The backIndicatorTransitionMask from a storyboard or a xib will not be interpreted correctly at runtime.Workaround: Set the backIndicatorTransitionMask in code.
As usual we will keep you updated with anything new, stay tuned.
