OK , color me stupid. What is pinching? and when do you use it? Only time I pinch is zooming back in after zooming out. I just tried some pinching instead of tapping and it was useless choosing anything, whatever the first pincher finger tapped got chosen.
I suspect a large number of users feel this way because they didn't really document very well how double tapping works.
First, to prevent selecting you need to tap quickly in the same spot. Make sure its a clear double tap.
I had a difficult time at first understanding why a double tap would sometimes zoom way in and other times it wouldn't zoom in much at all. It has to do with the column. Apple mentions this, but doesn't really play it up. But really, it's that simple. Look for a column or a field that if zoomed in will fill the width of the screen. Double tap on that field then scroll around if you need. This is very useful for zooming into the little 1 2 3 4 's at the bottom of the screen to move into another psge on the forum. Sometimes it's best not to double tap on the item you want to look at but instead a nearby smaller field or column.
Now that I know how tapping is supposed to work I fwel that the ponchong is more of a workaround for frustrated users snd an excuse to show off the high technology behons Apple. Frankly, I find double tapping to be quite slick.
Now if u (wait that's supposed to be an 'I' nou a 'u' - iPhone didn't correct it.) figure out this aito correctibg spell chrcj thing everybody loves so much. Lol
