- (ibaction)colorcontroller:(id)sender {  if (controller.selectedsegmentindex == 0) {      //app title text color      apptitle.textcolor =  [uicolor colorwithred:1.00 green:1.00 blue:0.00 alpha:1.0];      //background color when selected     controller.tintcolor = [uicolor colorwithred:1.00 green:1.00 blue:0.00 alpha:1.0];      //the font of selected     nsdictionary *fontcolor = [nsdictionary dictionarywithobjectsandkeys:                                [uicolor blackcolor],nsforegroundcolorattributename,                                nil];     [controller settitletextattributes:fontcolor forstate:uicontrolstateselected];    } if (controller.selectedsegmentindex == 1) {      //app title text color     apptitle.textcolor = [uicolor colorwithred:0.00 green:0.66 blue:1.00 alpha:1.0];      //background color when selected     controller.tintcolor = [uicolor colorwithred:0.00 green:0.66 blue:1.00 alpha:1.0];      //the font of selected     nsdictionary *fontcolor = [nsdictionary dictionarywithobjectsandkeys:                                [uicolor whitecolor],nsforegroundcolorattributename,                                nil];     [controller settitletextattributes:fontcolor forstate:uicontrolstateselected];  } if (controller.selectedsegmentindex == 2) {      //app title text color     apptitle.textcolor = [uicolor colorwithred:0.98 green:0.22 blue:0.22 alpha:1.0];      //background color when selected     controller.tintcolor = [uicolor colorwithred:0.98 green:0.22 blue:0.22 alpha:1.0];       //the font of selected     nsdictionary *fontcolor = [nsdictionary dictionarywithobjectsandkeys:                                [uicolor whitecolor],nsforegroundcolorattributename,                                nil];     [controller settitletextattributes:fontcolor forstate:uicontrolstateselected]; } if (controller.selectedsegmentindex == 3) {      //app title text color     apptitle.textcolor = [uicolor colorwithred:0.15 green:0.82 blue:0.44 alpha:1.0];      //background color when selected     controller.tintcolor = [uicolor colorwithred:0.15 green:0.82 blue:0.44 alpha:1.0];      //the font of selected     nsdictionary *fontcolor = [nsdictionary dictionarywithobjectsandkeys:[uicolor whitecolor], nsforegroundcolorattributename, nil];     [controller settitletextattributes:fontcolor forstate:uicontrolstateselected];  } 

}

now can see "apptitle" on first view controller automatically don't work. how can fix this. please link me somewhere / show me in not complicated way. (i have lots of labels too)

for purpose, use struct declared @ file level (not nested in sort of class). thus, should accessible throughout app. set value when change selected segment; value when loading view controller. here's example in swift:

struct setstruct {     var selseg: int = 0 } var settings = setstruct() 

in settings view controller viewdidload:

controller.selectedsegmentindex = settings.selseg 

in ibaction segmented control:

settings.selseg = controller.selectedsegmentindex
