Question

So I have a custom UISlider that I made with the following code:

UIImage *minImage = [UIImage imageNamed:@"settings_slider_fill.png"];
UIImage *maxImage = [UIImage imageNamed:@"settings_slider_empty.png"];
UIImage *tumbImage= [UIImage imageNamed:@"settings_slider_handle.png"];
minImage=[minImage stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0];
maxImage=[maxImage stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0];

[thresholdSlider setMinimumTrackImage:minImage forState:UIControlStateNormal];

[thresholdSlider setMaximumTrackImage:maxImage forState:UIControlStateNormal];

[thresholdSlider setThumbImage:tumbImage forState:UIControlStateNormal];

However this gives me a slider with an ugly square end on the left end. I have an image that I want to use for the left cap, but I don’t know how to programmatically set it as such.

This is the left end cap image I want to use:

This is the fill image I am using:

Answer 1

Turns out I can just use the end point and stretch it out rather than try to assign a dedicated left cap.
