I am creating review (Rating Stars) display from UISlider, having 2 images

all 5 white stars and
all 5 red stars.

Now when i display review like this:

    [slider_Rating setFrame:CGRectMake(0,0, 100, 25)];
    [slider_Rating setMinimumTrackImage:[UIImage imageNamed:@"review.png"] forState:UIControlStateNormal];
    [slider_Rating setMaximumTrackImage:[UIImage imageNamed:@"starsbackground.png"] forState:UIControlStateNormal];
    [slider_Rating setThumbImage:[UIImage imageNamed:@"volume.png"] forState:UIControlStateNormal];

But the issue is UISlider shrink the image instead of showing it according to the value. How can i do like for example when slider has 0.5 value it should show half of the image from left side?

Sample image of my issue

Or any other solution?

one solution is to crop images but this is not good solution – Kumar Jul 28 '15 at 10:41
so you have to do following thing- 1. use four diff. images (red full star, red half star, white full star and white half star). and then show images or repeat images according to slider value – Kumar Jul 28 '15 at 10:43
@LalitKumar no no i am having dynamic values from server side for rating... thats why i am using this – Nasir Khan Jul 28 '15 at 10:43
no problem it will work – Kumar Jul 28 '15 at 10:44
@LalitKumar no lalit you didnt understand .. i mean the rating value could be 4.237 or 1.85 so the slider value will also change like 0.42 or 0.89 – Nasir Khan Jul 28 '15 at 10:56
You could truncate or round the value from the slider – Kumar Jul 28 '15 at 11:10
the thing you want to try is not gonna work in any other way – Kumar Jul 28 '15 at 11:10

you may have to use ScrollView or use `contentMode` property – Kumar Jul 28 '15 at 11:15
