iOS - custom image for UISlider

Question

I want to use an image for the UISlider track. I don't want one color on the left of the thumb, and another color on the right. I just want one static image across the whole track. Possible?

Answer 1

For setting the image to your slider you can use the setMinimumTrackImage, setMaximumTrackImage methods. For your requirement set both to same image.

iOS 5 and Below

UIImage *sliderTrackImage = [[UIImage imageNamed: @"Slider.png"] stretchableImageWithLeftCapWidth: 7 topCapHeight: 0];

[mySlider setMinimumTrackImage: sliderTrackImage forState: UIControlStateNormal];
[mySlider setMaximumTrackImage: sliderTrackImage forState: UIControlStateNormal];

iOS 5+

UIImage *sliderTrackImage = [[UIImage imageNamed:@"Slider.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 7, 0, 0)];

[mySlider setMinimumTrackImage: sliderTrackImage forState: UIControlStateNormal];
[mySlider setMaximumTrackImage: sliderTrackImage forState: UIControlStateNormal];
