Slider to change variable

[Mr.Abe90]

How could i connect a UISlider to a specific variable where the user could use the slider to change the value of the variable and display the number? Some code would be great!

I'm assuming your doing this programmatically

slider.minimumValue = 0;
slider.maximumValue = 100;
float f = slider.value;
[label setText:[NSString stringWithFormat:@"%f.2"];//I do .2 so the float will go to second decimal place

note that if you want an int you need to do

int i = (int) slider.value;

How could i connect a UISlider to a specific variable where the user could use the slider to change the value of the variable? Here is some code other people have given me and none of it works.

float f = slider.value;

and

-(IBAction)yourMethod:(id)sender {
	UISlider *slider = (UISlider *)sender;
	[self setYourFloat:[slider value]];

If someone could please give me some WORKING code that would be great.

You already asked the same question in this thread: http://www.iphonedevsdk.com/forum/ip...-variable.html
There is no need to create multiple threads for the same question.

It didn't work.
And i know how to do the min/max and display the value, I just need the code for changing the variable with the slider.

You have to explain more than that. Saying "it didn't work" tells us nothing. What is your exact code, what happens when you run it, what did you expect to happen, do you get errors, if you do, which errors and on which lines, if nothing happens did you try putting a breakpoint and seeing if the code is being executed at all...
