1.一条属性

@property(nonatomic,retain)UISlider *slider;

2.设置滑块的基本内容

self.slider = [[UISlider
alloc] initWithFrame:CGRectMake(100,
400,
200, 20)];

[self.view

self.slider.minimumValue=0.5;

self.slider.maximumValue=5;
3.添加拖动方法

[self.slide addTarget:self action:@selector(sliderAction:)
forControlEvents:UIControlEventValueChanged];

4.方法的实现

self.tomcatImageView.animationDuration=slider.value;

[self.tomcatImageView
