IOS Double click on cell cause item in UITableView won't scroll

Question

I have a UITableView that contains UITextField in each cell
When I click UITextField in the cell, the keyboard will show and cover my cell. Therefore, I move my cell to the top by using.

- (void)keyboardWasShown:(NSNotification*)aNotification
{
    CGPoint scrollPoint = CGPointMake(0, self.activeInputView.frame.origin.y);
    [self.tableView setContentOffset:scrollPoint animated:YES];
}

If I use single click on each cell, my application work fine.
However, I use double click on each cell (it mean I tap on it 2 times very quickly), my cell will stop scroll to the top.

Answer 1

In this line

CGPoint scrollPoint = CGPointMake(0, self.activeInputView.frame.origin.y);

can be 2 errors.

Firstly, you have to make sure that inputView that you have captured is the view you want. Secondly, you should convert fetched point to correct view using appropriate method.
