我试图在iPhone 5模拟器上理解iOS 7.0中的新键盘动画.我想UITableView在键盘出现时调整大小,但我无法获得正确的动画细节.当键盘出现或消失时,
我正在使用来自NSNotification对象的信息.

这是我的日志:

Move keyboard from {{0, 920}, {320, 216}} to {{0, 352}, {320, 216}}
 with duration: 0.400000
 and animation curve: 7

UIViewAnimationCurveEaseInOut = 0
UIViewAnimationCurveEaseIn = 1
UIViewAnimationCurveEaseOut = 2
UIViewAnimationCurveLinear = 3

动画曲线是未知值,我该怎么办？

我一直在做这样的事情来模仿旧版iOS上的键盘动画.

CGRect keyboardBeginFrame;
[[note.userInfo objectForKey:UIKeyboardFrameBeginUserInfoKey] getValue:&keyboardBeginFrame];
self.doneKeyboardButton.frame = CGRectMake(0, (keyboardBeginFrame.origin.y + keyboardBeginFrame.size.height) - 53, 106, 53);
[[[[UIApplication sharedApplication] windows] lastObject] addSubview:self.doneKeyboardButton];

CGPoint newCenter = CGPointMake(self.doneKeyboardButton.superview.frame.origin.x + self.doneKeyboardButton.frame.size.width/2,
                                self.doneKeyboardButton.superview.frame.size.height - self.doneKeyboardButton.frame.size.height/2);

[UIView animateWithDuration:[[note.userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] floatValue]-.02
                      delay:.0
                    options:[[note.userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] intValue]
                 animations:^{
                     self.contentView.frame = CGRectOffset(self.contentView.frame, 0, -TextFieldViewMovement);
                     self.doneKeyboardButton.center = newCenter;
                 }
                 completion:nil];

但是,这已停止在iOS7上运行.看起来返回的值不再完全正确,完成按钮不再完全模仿键盘显示动画.
