iphone - UITableView with 3x3 grid button subviews -


im struggling work efficiently. need 3x3 scrolling grid of buttons. need know of these buttons pressed , following when create new cell

    button1 = [uibutton buttonwithtype:uibuttontypecustom];     button1.frame = cgrectmake(20, 20, 80, 80);     button1.opaque = no;     button1.showstouchwhenhighlighted = no;     [button1 addtarget:self action:@selector(buttonclick:)       forcontrolevents:uicontroleventtouchupinside];     button1.tag = 0;     [foodcell.contentview addsubview:button1];       button2 = [uibutton buttonwithtype:uibuttontypecustom];     button2.frame = cgrectmake(120, 20, 80, 80);     button2.opaque = no;     button2.showstouchwhenhighlighted = no;     [button2 addtarget:self action:@selector(buttonclick:)       forcontrolevents:uicontroleventtouchupinside];         button2.tag = 1;     [foodcell.contentview addsubview:button2];       button3 = [uibutton buttonwithtype:uibuttontypecustom];     button3.frame = cgrectmake(220, 20, 80, 80);     button3.opaque = no;     button3.showstouchwhenhighlighted = no;     [button3 addtarget:self action:@selector(buttonclick:)       forcontrolevents:uicontroleventtouchupinside];         button3.tag = 2;     [foodcell.contentview addsubview:button3];`
