Apple has just released iOS 7.1 beta 4 for app developers worldwide. Available either via the Settings app or the iOS Dev Center, it introduces a small number of changes, such as the slide to unlock text which now shows a silvery effect.

Notes and Known Issues
The following issues relate to using iOS SDK 7.1 beta 4 to develop code.
32-bit apps running on a 64-bit device cannot attach to BTServer.
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,
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.
Fixed in iOS 7.1 beta 4
Messages no longer indicates a send failure immediately after sending.
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”>.
- Bar button background images are ignored in apps built and deployed to iOS 7.1 when they are set using
UIBarButtonItemStyleBorderedas the style argument.
- If a
UILabelthat 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
UILabel, which should work as expected.
Workaround: Avoid making changes in
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.
backIndicatorTransitionMaskImagefrom a storyboard or a xib will not be interpreted correctly at runtime.
Workaround: Set the
backIndicatorTransitionMaskImage in code.
