UISlider Customisation

Transparent UISlider:

By default there is a default blue and white, selection for minimum and maximum image in iphone, what if you want a transparent image in them without having those images

Steps:

Add the slider in the interface builder and create an iboutlet for it in the code, then link them together

then in the -viewdidload- method use the following code, to make the UISlider transparent

 
    UIGraphicsBeginImageContextWithOptions((CGSize){ 1, 1 }, NO, 0.0f);    UIImage *transparentImage = UIGraphicsGetImageFromCurrentImageContext();    UIGraphicsEndImageContext();
    [slider setMinimumTrackImage:transparentImage forState:UIControlStateNormal];    [slider setMaximumTrackImage:transparentImage forState:UIControlStateNormal];

This should help you to get a transparent slider without any minimum and maximum images

Customized Minimum and Maximum Images:

If you want to customize it with your own images, then asusual link them together then in the viewdidload method use the following code.

Steps:

  UIImage *minImage = [UIImage imageNamed:@"min.png"];
  UIImage *maxImage = [UIImage imageNamed:@"max.png"];
  UIImage *tumbImage= [UIImage imageNamed:@"slidebutton.png"];  minImage=[minImage stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0];
  maxImage=[maxImage stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0];
  [slider setMinimumTrackImage:minImage forState:UIControlStateNormal];
  [slider setMaximumTrackImage:maxImage forState:UIControlStateNormal];
  [slider setThumbImage:tumbImage forState:UIControlStateNormal];
