애플, iOS 7.1 베타 버전 개발자에게 배포

애플은 최근 iOS 7.1 베타 버전을 개발자들에게 배포하기 시작했다. iOS7 출시 이후 첫 메이저 업데이트에 해당하는 iOS 7.1은 현재 iOS7에서 발견된 오류를 수정하는 데 초점을 맞춘 것으로 알려졌다.
현재 배포된 iOS는 iOS 7.0.4 버전으로 현재 페이스 타임 기능에 관련된 버그가 해결되지 않은 상태이다. 애플은 이 항목와 함께 현재까지 발견된 대부분의 오류를 iOS 7.1을 통해 수정할 것으로 알려졌다.

한편 iOS 7.1의 정식 배포 시기는 현재까지 알려지지 않았다.

" Notes and Known Issues
The following issues relate to using iOS SDK 7.1 to develop code.

Bluetooth
Known Issue
32-bit apps running on a 64-bit device cannot attach to BTServer.

CFNetwork
Fixed in iOS 7.1 beta
Previously, if the server-side closed an HTTP request with TCP FIN without sending any bytes of HTTP header or HTTP body, NSURLConnection would synthesize an empty HTTP/1.1 200 OK response. This is now fixed, and the request will result in an error instead of a successful load with a synthesized response.

Notes
A new 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.

Core Text
Fixed in iOS 7.1 beta
Previously, text drawn with CTFrameDraw did not correctly place lines to account for the paragraphSpacing attribute of NSParagraphStyle. This has been addressed in iOS 7.1 beta.

Crash Logs
Known Issue
Crash logs will not appear in Diagnostics & Usage Data in Settings. The logs will still be available when synced off the device.

GLKit
Fixed in iOS 7.1 beta
If loaded with GLKTextureLoader, pngcrush images that have alpha were not unpremultiplied.

High Precision Timers
Fixed in iOS 7.1 beta
When sleeping or waiting for extremely precise time intervals, timers were delayed by up to 1 millisecond.

iTunes
Known Issue
Loading an iTunes Match library (or your purchased music history) may take much longer than expected, especially on larger libraries. If your library does not sync right away, please wait 30 minutes and try to access it again.

Multipeer Connectivity
Fixed in iOS 7.1 beta
The MCSessioninitWithPeer: method has now been implemented properly.
