facebook ios api issues

Question

我在iOS上使用Facebook API，但登录后却收到此错误消息

Two-stage rotation animation is deprecated. This application should use the smoother single-stage animation.

Answer 1

The problem is that your app is using one of these methods, which were deprecated in iOS 5.0:

didAnimateFirstHalfOfRotationToInterfaceOrientation:
willAnimateFirstHalfOfRotationToInterfaceOrientation:duration:
willAnimateSecondHalfOfRotationFromInterfaceOrientation:duration:

You need to modify your view controllers to override willAnimateRotationToInterfaceOrientation:duration: instead, and to not override any of the "HalfOfRotation" methods.
