why not have int variable current position of string array , 2 methods goprev - gonext increments , decrements int variable.

in interface:

uibutton *btn; int step; nsarray *titles;

and in implementation:

-(void)setup { titles = [nsarray arraywithobjects:@"title 1",@"title 2",@"title 3",@"title 4", nil]; btn = [uibutton buttonwithtype:uibuttontypecustom]; } -(void)goprev { if (step>0) { step--; } [btn settitle:[titles objectatindex:step] forstate:uicontrolstatenormal]; } -(void)gonext { if (step<titles.count-1) { step++; } [btn settitle:[titles objectatindex:step] forstate:uicontrolstatenormal]; }
