ios - set UIslider thumb image in swift -


i want set thumb of musi app here ss

i want

enter image description here

i have

enter image description here

here code

        durationslider.setthumbimage(uiimage(named: "slider_indicator.png"), forstate: uicontrolstate.normal)     durationslider.setthumbimage(uiimage(named: "slider_indicator.png"), forstate: uicontrolstate.highlighted)

if want clip top part of thumbimage, should use:

public func thumbrectforbounds(bounds: cgrect, trackrect rect: cgrect, value: float) -> cgrect

so add code:

durationslider.thumbrectforbounds(...)

and set cgrect of thumbrect have value of durationslider.frame.origin.y own origin.y.

here's temporary solution, i'll thumbrectforbounds method shortly:

let mask = cagradientlayer(layer: durationslider.layer) let linetop = (durationslider.bounds.height/2 - 0.5) / durationslider.bounds.height mask.frame = durationslider.bounds mask.colors = [uicolor.clearcolor().cgcolor, uicolor.blackcolor().cgcolor] mask.locations = [linetop, linetop] durationslider.layer.mask = mask

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
