Question

I have a tableView with custom cells in it, each cell has a UISlider.

Now I want to create a method to get the values of those UISliders, but I don’t know how to access each cell and its slider value.

Thanks in advance!

Answer 1

First add a tag to each slider so you no which slider is which:

slider.tag = 0 //Can be any unique integer

Then register a method for slider changes:

[slider addTarget:self action:@selector(sliderUpdate:) forControlEvents:UIControlEventValueChanged];

Finally in your method

-(void)sliderUpdate:(UISlider *)sender {
    int value = sender.value;
    int tag = sender.tag;
}

Tag will now be the same unique integer you used before. It is a way of identifying the element.
