iphone - UITableViewCell reloadcellsAtIndexPaths increases the height of the following cell but not the actual one -

[self.tableview reloadrowsatindexpaths:[nsarray arraywithobject:[nsindexpath indexpathforrow:0 insection:0]] withrowanimation:uitableviewrowanimationnone]; 

after increasing height of 1st cell in heightforrowatindexpath. surprise increasing height of second cell, when scroll table view... height of first 1 set desired.

if reload entire table using [tv reloaddata] works fine.. not work if particular cell

any on helpful..

as written in comments above, have vague understanding want achieve. assume want extend cell changing height. mention first cell, guess, want able, cell when being clicked.

this code quite rough, extracted project in iphone-days. i.e. properties missing.
