Apple releases iOS 7.1 beta 3 to developers

The third beta of Apple’s iOS 7.1 was released to developers today, and is available through the iOS Dev Center. There are several changes to the user interface of calling and powering off, as well as the icons for Phone, Messages, and Facetime. Other changes include further UI tweaks and parallax options. Here are some photos of the changes, courtesy of 9t05mac. For the full gallery and list of changes, check out the live updating list here. The release notes are as follows: 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=”viewport” content=”width=1024, minimal-ui”>. UIKit Known Issues If 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.
