libc++abi.dylib: terminating with uncaught exception of type NSException
My Code:
RangeSlider *slider= [[RangeSlider alloc] initWithFrame:self.viewSlider.bounds];
[slider addTarget:self action:@selector(slidreDrag:) forControlEvents:UIControlEventValueChanged];
[self.viewSlider addSubview:slider];
Solve this issue solution me:
RangeSlider *slider= [[RangeSlider alloc] initWithFrame:self.viewSlider.bounds];
slider.minimumValue = [minValue floatValue];
slider.selectedMinimumValue = [minValue floatValue];
slider.maximumValue = [maxValue floatValue];
slider.selectedMaximumValue = [maxValue floatValue];
slider.minimumRange = 2;
[slider addTarget:self action:@selector(slidreDrag:) forControlEvents:UIControlEventValueChanged];
[self.viewSlider addSubview:slider];
Reason
you are doesn't set value of minimum, maximum that this value by default select NaN value this type error occur.
Please set value.
