[slider1 setBackgroundColor:[UIColor clearColor]];
slider1.minimumValue = 0.0;
slider1.maximumValue = 55.0;
slider1.continuous = YES;
slider1.value= 16
slider1.contentMode=UIViewContentModeScaleToFill;
[self.view addSubview:slider1];
slider2 = [[UISlider alloc] initWithFrame:frame];
[slider2 addTarget:self action:@selector(sliderActionMin:) forControlEvents:UIControlEventValueChanged];

slider2.continuous = YES;

推荐答案
您要在另一个滑块上方添加一个滑块.因此，根据Cocoa-Touch标准，只有Top(新添加)滑块会检测到所有事件.当您将两个滑块添加到相同的帧值时，第一个滑块将无法触摸.
You are adding one slider above another slider.So As per Cocoa-Touch standards, Only Top (newly added) slider will detect all events. First slider will be untouchable as you added both slider on same frame value.
