ios - Evenly space UIImageViews within UIScrollView -

i have uiscrollview in vc containing 9 image views size of 25px x 25 px on iphone 5s spaced in centre of scroll view. when ran on iphone 6 pushed on left, not stretching evenly across screen, due screen size.

is there way can make them evenly spaced on both screen sizes?

code below:

// set scrollview   nslog(@"%f", self.view.frame.size.width);  uiscrollview *scrollview = [[uiscrollview alloc] initwithframe:cgrectmake(25, 200, self.view.frame.size.width - 50, 30)];  scrollview.alwaysbouncehorizontal = yes;  nslog(@"%f", scrollview.frame.size.width);  uiview *view = [[uiview alloc] initwithframe:cgrectmake(0, 0, scrollview.frame.size.width, scrollview.frame.size.height)]; [scrollview addsubview:view];  uiimage *star = [uiimage imagenamed:@"badge_star"]; uiimageview *imgview = [[uiimageview alloc] initwithimage:star]; imgview.frame = cgrectmake(2.5, 5, 25, 25); [view addsubview:imgview];  uiimage *target= [uiimage imagenamed:@"badge_target"]; uiimageview *targetimageview = [[uiimageview alloc] initwithimage:target]; targetimageview.frame = cgrectmake(32.5, 5, 25, 25); [view addsubview:targetimageview];  uiimage *crown = [uiimage imagenamed:@"badge_crown"]; uiimageview *crownimageview = [[uiimageview alloc] initwithimage:crown]; crownimageview.frame = cgrectmake(62.5, 5, 25, 25); [view addsubview:crownimageview];  uiimage *scissors = [uiimage imagenamed:@"badge_scissors"]; uiimageview *scissorsimageview = [[uiimageview alloc] initwithimage:scissors]; scissorsimageview.frame = cgrectmake(92.5, 5, 25, 25); [view addsubview:scissorsimageview];  uiimage *thumbsup = [uiimage imagenamed:@"badge_thumbs_up"]; uiimageview *thumbsupimageview = [[uiimageview alloc] initwithimage:thumbsup]; thumbsupimageview.frame = cgrectmake(122.5, 5, 25, 25); [view addsubview:thumbsupimageview];  uiimage *trophy = [uiimage imagenamed:@"badge_trophy"]; uiimageview *trophyimageview = [[uiimageview alloc] initwithimage:trophy]; trophyimageview.frame = cgrectmake(152.5, 5, 25, 25); [view addsubview:trophyimageview];  uiimage *medal = [uiimage imagenamed:@"badge_medal"]; uiimageview *medalimageview = [[uiimageview alloc] initwithimage:medal]; medalimageview.frame = cgrectmake(182.5, 5, 25, 25); [view addsubview:medalimageview];  uiimage *heart = [uiimage imagenamed:@"badge_heart"]; uiimageview *heartimageview = [[uiimageview alloc] initwithimage:heart]; heartimageview.frame = cgrectmake(212.5, 5, 25, 25); [view addsubview:heartimageview];  uiimage *coathanger = [uiimage imagenamed:@"badge_coathanger"]; uiimageview *coathangerimageview = [[uiimageview alloc] initwithimage:coathanger]; coathangerimageview.frame = cgrectmake(242.5, 5, 25, 25); [view addsubview:coathangerimageview];  [self.view addsubview:scrollview];   } 

that because hard coding start point of scroll view. have 2 option;
1. increase spacing between each image or
2. change start point of scroll view
opting 2nd option relatively easy in code. use below code scroll view frame.

float scrollviewwidth = 25*9+5*8+2*2.5; // cross check one.   float xscrollpoint = (self.view.frame.size.width - scrollviewwidth)/2    uiscrollview *scrollview = [[uiscrollview alloc] initwithframe:cgrectmake(xscrollpoint, 200, scrollviewwidth, 30)];
