Question

I have a UITextView that has a fixed width and height. I pre-populate the entire textfield with blanks.

I would like to insert a character with the push of a button that will erase the last blank character, insert my string character and then place the cursor at the beginning of the newly inserted string. I am trying to achieve inserting special fonts right to left and bottom to top.

It is working with the first button push and on the second button push the new value is inserted in the correct position to the left, however, the cursor will not move to the left after the second button push, it remains to the right after the second string insert.

Here is my code…

-(IBAction)chartP:(id)sender {
    NSRange currentRange = myChart.selectedRange;
    if (currentRange.length == 0) {
        currentRange.location--;
        currentRange.length++;
    }
    myChart.text = [myChart.text stringByReplacingCharactersInRange:currentRange
        withString:[NSString string]];
    currentRange.length = 0;
    myChart.selectedRange = currentRange;

    myChart.text = [myChart.text stringByAppendingString:@"p"];

    myChart.selectedRange = NSMakeRange(myChart.selectedRange.location -1, 0);
}

Can someone assist me with what I am missing here to continually increment to the left with my string inserts?

How about flipping the text area:

myChart.transform = CGAffineTransformMakeScale(-1,-1);
