点击之定义tableviewcell,弹出键盘,通过距离判断解决键盘遮挡问题;
核心代码是如果tableview上的cell判断被遮挡 可以通过改变contentInset和滚动tableview到指定cell来实现

}关键函数:
1.计算 cell相对于View的高度 并计算出他是否被遮挡
UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];
WZCPHuiFuPingLunTabCell *cell = [self.myTableView cellForRowAtIndexPath:self.curIndex];
CGRect selfFrame = [cell convertRect:cell.frame toView:keyWindow];
//将试图的Y坐标向上移动offset个单位，以使界面腾出开的地方用于软键盘的显示
CGFloat offSet = selfFrame.origin.y - (keyWindow.frame.size.height - kbRect.size.height);
2.给键盘留出空间
// 改变tableview内部空间
self.myTableView.contentInset = UIEdgeInsetsMake(0, 0, kbRect.size.height, 0);
3.让tableview滚动到相应的cell部
//滚动到cell的样式UITableViewScrollPositionBottom
[self.myTableView scrollToRowAtIndexPath:self.curIndex atScrollPosition:UITableViewScrollPositionBottom animated:YES];
