I have an app that runs perfectly on iOS 6. I\'ve set a blinking effect to a UISlider\'s thumb this way:
-(void)startBlinkingSlider{
isSliderBlinking = Y
I discovered a workaround. By first calling the 'setThumbImage:forState:' method, the 'thumbTintColor' property will then take effect.
[self.slider setThumbImage:[UIImage imageNamed:@"Thumb.png"]
forState:UIControlStateNormal];
self.slider.thumbTintColor = [UIColor blackColor];
I tested this on Version 7.0 (463.9.4.2) of iOS Simulator.
