I am having a UISlider in my parent view. I want to honor the Voice-over gestures for slider movement and thus, i have implemented accessibilityIncrement and accessibilityDecrement methods as below:
- (void)accessibilityIncrement
{
float finalValue = self.value;
finalValue = (finalValue + 1);
if (finalValue > self.maximumValue)
finalValue = self.maximumValue;
self.value = finalValue;
}
- (void)accessibilityDecrement
{
float finalValue = self.value;
finalValue = (finalValue - 1);
if (finalValue < self.minimumValue)
finalValue = self.minimumValue;
self.value = finalValue;
}
The issue is when I set the value of the slider (using self.value = finalValue), the selector for UIControlEventValueChanged event does not get called. Is this a Bug?
Thanks!
对于带有VoiceOver的UISlider
, 推荐的解决方案包括在代码中使用委托 ,使用已经使用的increment
和decrement
方法根据旋钮位置调整滑块值。
