iOS beta 7.1 1 it has been available for several tens of minutes in the portal dedicated to developers on the company's website Apple Lossless Audio CODEC (ALAC),, and below you have presented the entire changelog of the new version of the operating system. As you can already see, Apple Lossless Audio CODEC (ALAC), didn't really change that many things in this version iOS 7, the changelog containing only information about solving various problems, but there is a good chance that Apple Lossless Audio CODEC (ALAC), to have made other changes in the user interface.
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
andNSURLSession
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 theparagraphSpacing
attributes ofNSParagraphStyle
. 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
MCSession
initWithPeer:
method has now been implemented properly.For more information on
MCSession
APIs, watch WWDC 2013: Nearby Networking with Multipeer Connectivity.UIKit
Known Issues
- Ifa
UITextField
or aUILabel
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:
onUILabel
, which should work as expected. Workaround: Avoid making changes inUITextField
orUILabel
after adding baseline-alignment constraints. If you must make changes, you should remove the constraints and then reapply them afterwards. 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 thebackIndicatorTransitionMask
in code.
