我想让我的 UISlider 可点击 - 将点击时的值更改为“空白”,例如它设置为零,我单击 slider 的中间,它会“跳”到中间。有没有办法做到这一点?

我想提出类似于 jrtc27 的东西,但没有子类化:添加 UI(Tap)GestureRecognizer 到 slider 。
UISlider *slider = [[[UISlider alloc] init] autorelease];
//configure slider
UITapGestureRecognizer *tapGestureRecognizer = [[[UITapGestureRecognizer alloc] initWithTarget:self actionselector(sliderTapped] autorelease];
[slider addGestureRecognizer:tapGestureRecognizer];
- (void)sliderTappedUIGestureRecognizer *)gestureRecognizer {
UISlider *slider = (UISlider *) gestureRecognizer.view;
//setValue
}
关于objective-c - 可点击的 UISlider,我们在Stack Overflow上找到一个类似的问题:
