Apple iOS 7.1 Beta 4 Release:

Apple has just seeded iOS 7.1 beta 4 to developers after the rumors hinted its launch tomorrow. You can download the iOS 7.1 beta 4 from iOS Dev Center.

[Update]: iOS 7.1 beta 4 changelog:

Here is the iOS 7.1 Beta 4 changelog:

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.

Messages fixed in iOS 7.1 beta 4

Messages no longer indicates a send failure immediately after sending.

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

• Bar button background images are ignored in apps built and deployed to iOS 7.1 when they are set using UIBarButtonItem setBackgroundImage:forState:style:barMetrics: with UIBarButtonItemStyleBordered as the style argument.Workaround: Use UIBarButtonItemStylePlain or UIBarButtonItemStyleAny in this case, or use UIBarButtonItem setBackgroundImage:forState:barMetrics:.
• 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 backIndicatorTransitionMaskImage from a storyboard or a xib will not be interpreted correctly at runtime.Workaround: Set the backIndicatorTransitionMaskImage in code.
