iOS - UI - UISlider

6、UISlider

//滑块   设置高度

UISlider * slider = [[UISlider alloc] initWithFrame:CGRectMake(20, 100, CGRectGetWidth(self.view.frame) - 40,30 )];

//    slider.backgroundColor = [UIColor grayColor];

slider.minimumValue = 10;

slider.maximumValue = 50;

//较小值轨道颜色

slider.minimumTrackTintColor = [UIColor greenColor];

//较大值轨道颜色

slider.maximumTrackTintColor = [UIColor redColor];

//拖动圆圈的颜色

slider.thumbTintColor = [UIColor yellowColor];

slider.value = 30;

//能否连续调用valuechange

slider.continuous = NO;

//最小端添加图片

slider.minimumValueImage = [UIImage imageNamed:@"apply_sex_normal"];

//最大端添加图片

slider.maximumValueImage = [UIImage imageNamed:@"apply_sex_selected"];

//滑块的图片

[slider setThumbImage:[UIImage imageNamed:@"apply_sex_selected"] forState:UIControlStateNormal];

//较小端轨道的图片

[slider setMinimumTrackImage:[UIImage imageNamed:@"apply_sex_normal"] forState:UIControlStateNormal];

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

[self.view addSubview:slider];

}

- (void)sliderAction:(UISlider *)slider {

self.switchLabel.font = [UIFont systemFontOfSize:slider.value];

}
