Incorrect math
On line 176 in SlideToCancelViewController.m, it reads:
- (void) sliderChanged: (UISlider *) sender
{
// Fade the text as the slider moves to the right. This code makes the
// text totally dissapear when the slider is 35% of the way to the right.
label.alpha = MAX(0.0, 1.0 - (slider.value * 3.5));
// Stop the animation if the slider moved off the zero point
if (slider.value != 0) {
[self stopTimer];
[label.layer setNeedsDisplay];
}
}
Lines 178-180:
// Fade the text as the slider moves to the right. This code makes the
// text totally dissapear when the slider is 35% of the way to the right.
label.alpha = MAX(0.0, 1.0 - (slider.value * 3.5));
It's not true. It makes the text disappear when it reaches 1/3.5 which is approx. 28.6 %. The corrected line 180 would be:
label.alpha = MAX(0.0, 1.0 - (slider.value / 0.35));
