uislider

问题 When releasing the touch on a UISlider the value of the slider changes slightly and uncontrollably. It's so sensitive that it even changes when just releasing the finger from the screen. How can I achieve that the user can set a value he wants without problems? That's how I create my UISlider: UISlider *slider = [[UISlider alloc] initWithFrame: CGRectMake(100.0, 100.0, 200.0, 40.0)]; slider.minimumValue = 0.0; slider.maximumValue = 100.0; [slider addTarget: self action: @selector

问题 I have, after many tutorials and lots of time, managed to build a slider with jQuery. However, it's not working as smoothly as I would have hoped. I have used a custom handle, and seeing as the new jQueryUI doesn't have a handle option, I have created a handle in CSS. However, this handle is going beyond the required bounds of the slider. I have uploaded a test page which can be found here. My code is as follows: CSS <style type="text/css" media="screen"> <!-- body { padding: 0; font: 1em

问题 I want to put a slider with two selector points as a range into a UITableViewCell (in static UITableView). I tried this library https://github.com/muZZkat/NMRangeSlider But It doesn't work.

问题 I'm trying to offset the x/y position of a UISlider's min and max value images. Currently, I'm sublcassing UISlider and am setting the maximum value image like this: [self setMaximumValueImage:[UIImage imageNamed:@"circle_with_plus"]]; However, I need this image to be closer to the actual UISlider and have little control over visual assets on this project.
