UISlider(滑块控件)

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 addSubview:self.slider];

    [_slider release];

//最大值 最小值

    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

-(void)sliderAction:(UISlider *)slider

{

    NSLog(@"%g",slider.value);

    //播放时长,被slider控制

 self.tomcatImageView.animationDuration=slider.value;

    [self.tomcatImageView startAnimating];

}
