According to developer.apple I should be able to set UISLider's property - thumbTintColor/minimumTrackTintColor/maximumTrackTintColor - reference http://developer.apple.com/library/IOs/#documentation/UIKit/Reference/UISlider_Class/Reference/Reference.html
But setting any of these properties raises "unrecognized selector sent to instance" exception.
I know there is a workaround for this by setting image properties. But I don't want to go that way. Is there anything I'm missing?
Please any help is appreciated. Thanks in advance.
Here is the code from UICatalog project of developer.apple examples:
- (UISlider *)sliderCtl
{
if (sliderCtl == nil)
{
CGRect frame = CGRectMake(174.0, 12.0, 120.0, kSliderHeight);
sliderCtl = [[UISlider alloc] initWithFrame:frame];
[sliderCtl addTarget:self action:@selector(sliderAction:) forControlEvents:UIControlEventValueChanged];
// in case the parent view draws with a custom color or gradient, use a transparent color
sliderCtl.backgroundColor = [UIColor clearColor];
// I just added this following line to test
sliderCtl.thumbTintColor = [UIColor yellowColor];
sliderCtl.minimumValue = 0.0;
sliderCtl.maximumValue = 100.0;
sliderCtl.continuous = YES;
sliderCtl.value = 50.0;
// Add an accessibility label that describes the slider.
[sliderCtl setAccessibilityLabel:NSLocalizedString(@"StandardSlider", @"")];
sliderCtl.tag = kViewTag; // tag this view for later so we can remove it from recycled table cells
}
return sliderCtl;
}

You are trying to do this on not iOS5 devices/simulators. The API you want to use are only available on iOS5.
