iphone - Dynamic expandable UITableView with sections -

i creating uitableview expandable/collapsable sections.

i data internet in json format, storing in arrays :

{section 1 {s1 data 1, s1 data 2, ... }, section 2 {s2 data 1, s2 data 2, , on}}

sections can alphabetical letters, year number or whatever.

i create table view headers :

gtheaderview *header = [gtheaderview headerviewwithtitle:[nsstring stringwithformat:@"%@", myarray.sectionvalue]]; [header.button addtarget:self action:@selector(togglesection) forcontrolevents:uicontroleventtouchupinside]; 

this fine, in "togglesection" method, can't find way know witch section have been touched collapsed/expanded.

i know can't send parameters in selector... solution think fit needs ?

thanks in advance !

you can write togglesection method as:

- (void)togglesection:(id)sender {    // send sender object message find out section number here... } 

and of course change addtarget line specify togglesection method has 1 parameter:

[header.button addtarget:self action:@selector(togglesection:) forcontrolevents:uicontroleventtouchupinside];
