可点击的UISlider [英] Clickable UISlider

问题描述

我想让我的UISlider可点击 - 将点击值更改为空格，例如它被设置为零，我点击滑块的中间，它将跳到中间。有什么方法可以做到这一点吗？

I'd like to make my UISlider clickable - to change the value on click to "blank space", e.g. It's set to zero, I click in the middle of the slider and it will "jump" to the middle. Is there any way how to do this?

推荐答案

我想提出类似于jrtc27的东西，但是没有子类化：添加一个< a href =https://developer.apple.com/library/ios/#documentation/uikit/reference/UIGestureRecognizer_Class/Reference/Reference.html\"rel =nofollow> UI（点击）GestureRecognizer 到滑块。

I want to propose something similar as jrtc27, but without subclassing: add a UI(Tap)GestureRecognizer to the slider.

UISlider *slider = [[[UISlider alloc] init] autorelease];
//configure slider
UITapGestureRecognizer *tapGestureRecognizer = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(sliderTapped:)] autorelease];
[slider addGestureRecognizer:tapGestureRecognizer];


- (void)sliderTapped:(UIGestureRecognizer *)gestureRecognizer {
    UISlider *slider = (UISlider *) gestureRecognizer.view;
    //setValue 
}
