uislider

问题 I've seen this question asked in other areas but none of the answers work in my case. I have a UIPageViewController that has a child view controller containing a UISlider. When you go to try to move the slider, it activates the page view controller's scrolling instead. You have to tap, pause on the slider circle, and then move. The UIPageViewController is set to the scroll type, and thus the gestureRecognizers are not set. (The header states "Only populated if transition style is

问题 I want to move a UISlider from minValue to maxValue in a loop when you hit a button and stop it at the current position when hitting the button again, I want to use Swift. The main problem i got is that the function slider.setValue() is way to fast, I want the animation more slowly. @IBAction func setSliderValue(_ sender: UIButton){ slider.setValue(100, animated: true) print("The value of the slider is now \(slider.value)") sliderValue = Int(slider.value) } 回答1: You can use time to

问题 I have a UI slider that is continuous. I take the value as it changes and use it to calculate a value that i put into a textfield. I have the value changed outlet linked to the method that does the calculation and that works ok but i also want a method to fire once the user lifts off the slider that effectively gives a once time evaluation of the final set value. I have tried connecting the the did end on exit method and others available . 回答1: Use the UISlider's UIControlEventTouchUpInside

问题 I have a problem with the R shiny slider input. The "Round feature" does not work as you can see in in this picture. Did I do something wrong ? sliderInput("Er", "Choose expected return (in percent)", min = min, max = max, value = min , round = -1, sep = "" , post = "%", ticks = FALSE ) 回答1: You have to specify a step for round ing to work: library(shiny) min_Er <- 20.31 max_Er <- 23.59 shinyApp( ui = fluidPage(sliderInput("Er1", "Rounding doesn't work", round = -2, step = NULL, min = min_Er,

问题 I have a UISlider I implemented with JQuery UI . I want to add a legend under the slider showing the numbers. I followed this answer which showed how to implement that, placing then numbers with percentage values. This way when the sliders size changes, (ex. browser gets resized,) the numbers are still at the correct places. That works fine and well, but if the browsers window is small, or if there are a lot of numbers for the slider, then the legend number get too close to each other.

问题 How is it possible to set the min max ranges of the UISlider programmatically? For example (dummy code) UISlider* slider = [[UISlider alloc] init]; slider.min = -3; slider.max = 3; EDIT: So I have the following: sl.minimumValue = 5; NSLog(@"MIN VAL: %d", sl.minimumValue); This doesn't work, I still get it logging the value 0. Is this because I have set values in interface builder? 回答1: Here is it. UISlider* slider = [[UISlider alloc] init]; slider.minimumValue = -3.0f; slider.maximumValue = 3

问题 I have to place a slider and want to place an imge on slider. the slider i want is this CAn any body help me? 回答1: See the UISlider class reference. You want to set setThumbImage:forState: as well as setMinimumTrackImage:forState: and setMaximumTrackImage:forState: . Use the same images for the minimum and maximum track images, and use UIControlStateNormal for the state. 回答2: Below code will be in ViewWillAppear... -(void)viewWillAppear:(BOOL)animated { slider.backgroundColor = [UIColor
