UITableView中cell里的UITextField不被弹出键盘挡住
本人视频教程系类 iOS中CALayer的使用
效果如下：

}
#pragma mark - UITextField代理
- (void)textFieldDidBeginEditing:(UITextField *)textField {
// 获取到临时的textField并存储起来
self.tmpTextField = textField;
// 获取到父类cell
EditCell *cell = (EditCell *)[self.tmpTextField superview];
// 获取到indexPath
NSIndexPath *path = [self.tableView indexPathForCell:cell];
// 执行动画(移动到输入的位置)
[self.tableView setContentOffset:CGPointMake(0, (path.row)*44) animated:YES];
}
- (void)textFieldDidEndEditing:(UITextField *)textField {
// 获取到临时的textField并存储起来
self.tmpTextField = textField;
// 获取到父类cell
EditCell *cell = (EditCell *)[self.tmpTextField superview];
// 获取到indexPath
NSIndexPath *path = [self.tableView indexPathForCell:cell];
// 存储到数据源中
[_strsArray replaceObjectAtIndex:path.row
withObject:(textField.text == nil ? @"" : textField.text)];
// 打印信息
NSLog(@"%@", _strsArray);
}
- (BOOL)textFieldShouldReturn:(UITextField *)sender {
// 执行动画(恢复到原始位置)
[self.tableView setContentOffset:CGPointMake(0, 0) animated:YES];
// 交出第一响应者
[sender resignFirstResponder];
return YES;
}
@end以下是需要注意的地方：
通过父视图获取到了cell，然后根据cell获取indexPath值，然后可以做事情了
核心代码是根据第几个cell来执行位移的动画，这个值是可以调整的。
