Question

I need to implement such kind of functionality in my slider such that the submit button should not appear till the user pull up his fingers from slider.
Is there any kind of function which can duplicate this.

Thanks,

If you can’t set continuous to NO for some reason, observe the UIControlEventTouchUpOutside and UIControlEventTouchUpInside events:

[yourSlider addTarget:self 
               action:@selector(showSubmit:) 
     forControlEvents:UIControlEventTouchUpInside|UIControlEventTouchUpOutside];

And

- (void)showSubmit:(UISlider *) {
    // code to show your button here
}
