我有一个视图控制器,可以用新的交互式PopGestureRecognizer弹出。如果存在键盘并且轻扫动画开始,则键盘不会随视图移动。我看过这个问题,并在我的视图控制器中像这样实现它,但被驳回了
-(void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[self.transitionCoordinator animateAlongsideTransitionInView:self.aTextInputView.keyboardSuperView animation:^(id<UIViewControllerTransitionCoordinatorContext> context) {
CGRect frame = self.aTextInputView.keyboardSuperView.frame;
frame.origin.x = self.view.frame.size.width;
self.aTextInputView.keyboardSuperView.frame = frame;
} completion:nil];
}
现在,当视图动画消失时,我得到的是键盘动画离开屏幕到 320 的 x 点,这是有道理的,因为这就是我设置的,我的问题是我如何让键盘动画与向后滑动?
更新
对于任何在视图消失时看到奇怪动画的人,您可以通过执行此操作来移除键盘。
[self.transitionCoordinator notifyWhenInteractionEndsUsingBlock:^(id<UIViewControllerTransitionCoordinatorContext> context){
if (![context isCancelled]) {
[keyboardSuperview removeFromSuperview];
}
}];
你的代码段中有很多自定义代码,如果我错了,请纠正我,但似乎你的self.aTextInputView.keyboardSuperView
不正确。
仔细检查它是否nil
。如果是,您忘记添加inputAccessoryView
。
以下是没有任何扩展名的完整代码片段:
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
UIView *keyboardSuperview = self.textField.inputAccessoryView.superview;
[self.transitionCoordinator animateAlongsideTransitionInView:keyboardSuperview
animation:
^(id<UIViewControllerTransitionCoordinatorContext> context) {
CGRect keyboardFrame = keyboardSuperview.frame;
keyboardFrame.origin.x = self.view.bounds.size.width;
keyboardSuperview.frame = keyboardFrame;
}
completion:nil];
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.textField.inputAccessoryView = [[UIView alloc] init];
}
刚刚为iOS8找到了非常简单的解决方案
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[self.aTextInputView resignFirstResponder];
}
