how do i only allow one selected button at once?

how make these buttons 1 can used @ time? im not getting errors right when run btw. im looking solution challenge. help

generated in loop this:

code:

    (int l=0; l<list.length; l++) {                uibutton *abutton = [uibutton buttonwithtype:uibuttontyperoundedrect];          [abutton settag:l];          cgrect buttonrect = cgrectmake(11+charact*20, -40 + line*50, 18, 21);          abutton.frame = buttonrect;                    [abutton addtarget:self action:@selector(buttonclicked:) forcontrolevents:uicontroleventtouchupinside];          [abutton settitle:@" " forstate:uicontrolstatenormal];          [gamescroll addsubview:abutton];  }  

and action when button clicked is:

code:

- (void) buttonclicked:(uibutton *)sender {        int tag = sender.tag;        if (sender.selected == true) {          [sender setselected:false];          [sender setbackgroundcolor:[uicolor clearcolor]];      }      else if (sender.selected == false) {          [sender setselected:true];          [sender setbackgroundcolor:[uicolor redcolor]];      }  }

right works want know if theres button selected , deselect other button, or else automatically deselect time user clicks outside of range of button

in advance

click expand...

"can used" translates button.enabled not button.selected. if want de-select button when button b pressed

code:

[buttona setselected:(!buttonb.selected)]
