Ios 我想在单击按钮时设置UITableView的动画

我有

UITableView

，我想在用户单击按钮时设置动画

对于所选状态-->自下而上

对于未选择的状态-->从上到下

为此，我尝试了以下代码。 我的桌面视图框架（0,39，宽度，高度）

当我点击按钮时，它将正确地从底部到顶部设置动画。

但当我再次单击按钮时，它将再次从底部转到顶部

因为您已将tableview的

frame.origin.y

设置为-y或XY坐标

    self.tblVWInviteFriend.frame = CGRectMake(0, -[UIScreen mainScreen].bounds.size.height, self.tblVWInviteFriend.frame.size.width, self.tblVWInviteFriend.frame.size.height);

换成这个

    self.tblVWInviteFriend.frame = CGRectMake(0, [UIScreen mainScreen].bounds.size.height, self.tblVWInviteFriend.frame.size.width, self.tblVWInviteFriend.frame.size.height);

试试这个：

- (IBAction)onInviteFriendsButtonClick:(UIButton *)sender {
    sender.selected =! sender.selected;

    if (sender.selected) {
        CGRect napkinBottomFrame = txtAOP.frame;
        napkinBottomFrame.origin.y = [UIScreen mainScreen].bounds.size.height;
        txtAOP.frame = napkinBottomFrame;
        [UIView animateWithDuration:0.5 delay:0.0 options: UIViewAnimationOptionTransitionCurlUp animations:^{
            txtAOP.frame = CGRectMake(0, 39, txtAOP.frame.size.width, txtAOP.frame.size.height);
        } completion:^(BOOL finished){/*done*/}];
    }
    else {
        CGRect napkinBottomFrame = txtAOP.frame;
        napkinBottomFrame.origin.y = -[UIScreen mainScreen].bounds.size.height;
        txtAOP.frame = napkinBottomFrame;
        [UIView animateWithDuration:0.5 delay:0.0 options: UIViewAnimationOptionTransitionCurlDown animations:^{
            txtAOP.frame = CGRectMake(0,39 , txtAOP.frame.size.width, txtAOP.frame.size.height);
        } completion:^(BOOL finished){/*done*/}];
    }
}

- (IBAction)onInviteFriendsButtonClick:(UIButton *)sender {
    sender.selected =! sender.selected;

    if (sender.selected) {
        CGRect napkinBottomFrame = txtAOP.frame;
        napkinBottomFrame.origin.y = [UIScreen mainScreen].bounds.size.height;
        txtAOP.frame = napkinBottomFrame;
        [UIView animateWithDuration:0.5 delay:0.0 options: UIViewAnimationOptionTransitionCurlUp animations:^{
            txtAOP.frame = CGRectMake(0, 39, txtAOP.frame.size.width, txtAOP.frame.size.height);
        } completion:^(BOOL finished){/*done*/}];
    }
    else {
        CGRect napkinBottomFrame = txtAOP.frame;
        napkinBottomFrame.origin.y = -[UIScreen mainScreen].bounds.size.height;
        txtAOP.frame = napkinBottomFrame;
        [UIView animateWithDuration:0.5 delay:0.0 options: UIViewAnimationOptionTransitionCurlDown animations:^{
            txtAOP.frame = CGRectMake(0,39 , txtAOP.frame.size.width, txtAOP.frame.size.height);
        } completion:^(BOOL finished){/*done*/}];
    }
}
