How can I hide the UISlider track?

Question

I've created a slider track that is draw on the actual background of my app and I've also drawn the UISlider thumb image. I know how to set the thumb image for the slider. But how do I hide the UISlider track?

If you do not want to use transparent images, you can just set the track images to empty UIImage objects:

[slider setMinimumTrackImage:[UIImage alloc] forState:UIControlStateNormal];
[slider setMaximumTrackImage:[UIImage alloc] forState:UIControlStateNormal];

I realize this is a separate question, but are there any potential repercussions from not calling init on those images? – livingtech Jun 06 '13 at 19:39

There should be no repercussions of not using init. The init method usually just sets default properties of an object, which are not required for UIImage. However, using [[UIImage alloc] init] or [UIImage new] will have the same effect in this case. – Avario Jun 07 '13 at 01:24

Use a 1px transparent image for the min and max track images. I answered this very same question yesterday.
