在我的 View 中,我的 UITableViewCell 中有一个 UITextField。现在有可能 UITextField 可能在我的键盘后面,所以我使用以下两种方法正确处理。一个用于单击键盘时,另一个用于关闭键盘时:
- (void)keyboardNotification:(NSNotification*)notification {
CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
CustomCell *cell = (CustomCell*)[[tempTextField superview] superview];
CGRect textFieldRect = [cell convertRect:tempTextField.frame toView:self.view];
if (textFieldRect.origin.y + textFieldRect.size.height >= [UIScreen mainScreen].bounds.size.height - keyboardSize.height) {
thetableView.contentInset = UIEdgeInsetsMake(0, 0, keyboardSize.height, 0);
NSIndexPath *pathOfTheCell = [thetableView indexPathForCell:cell];
[thetableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:pathOfTheCell.row inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:YES];
}
}
- (void)keyboardhideNotification:(NSNotification*)notification {
thetableView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0);
}
现在它工作得有些好,但是有两个问题。

.当键盘位于键盘下方并且表格 View 向上滚动时,它会以一种很好的动画方式进行,但是当我单击完成时,它会立即弹回旧位置。我可以清楚地看到为什么会发生这种情况,但是我将如何制作漂亮的动画以恢复到 tableview 所在的旧位置?
任何投入将不胜感激!
更新:我设法找到了#1 的问题。这是一个愚蠢的错误。应该将 textField 的高度添加到原点,因为该测量值正在下降。现在进入#2 ...
最佳答案
此代码简单地修复了 1 和 2:
- (void)keyboardNotification:(NSNotification*)notification {
CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
CustomCell *cell = (CustomCell*)[[tempTextField superview] superview];
CGRect textFieldRect = [tempTextField convertRect:tempTextField.frame toView:self.view];
if (textFieldRect.origin.y + textFieldRect.size.height >= [UIScreen mainScreen].bounds.size.height - keyboardSize.height) {
NSDictionary *info = [notification userInfo];
NSNumber *number = [info objectForKey:UIKeyboardAnimationDurationUserInfoKey];
double duration = [number doubleValue];
[UIView animateWithDuration:duration animations:^{
thetableView.contentInset = UIEdgeInsetsMake(0, 0, keyboardSize.height, 0);
}];
NSIndexPath *pathOfTheCell = [thetableView indexPathForCell:cell];
[thetableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:pathOfTheCell.row inSection:0] atScrollPosition:UITableViewScrollPositionMiddle animated:YES];
}
}
- (void)keyboardhideNotification:(NSNotification*)notification {
NSDictionary *info = [notification userInfo];
NSNumber *number = [info objectForKey:UIKeyboardAnimationDurationUserInfoKey];
double duration = [number doubleValue];
[UIView animateWithDuration:duration animations:^{
thetableView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0);
}];
}
