UISlider用法总结

@property(nonatomic) float value; 

这个值是介于滑块的最大值和最小值之间的,如果没有设置边界值,默认为0-1;

设置滑块最小边界值(默认为0)

@property(nonatomic) float minimumValue;  

设置滑块最大边界值(默认为1)

@property(nonatomic) float maximumValue;

设置滑块最左端显示的图片:

@property(nonatomic,retain) UIImage *minimumValueImage

设置滑块最右端显示的图片:

@property(nonatomic,retain) UIImage *maximumValueImage;

设置滑块值是否连续变化(默认为YES)

@property(nonatomic,getter=isContinuous) BOOL continuous; 

这个属性设置为YES则在滑动时,其value就会随时变化,设置为NO,则当滑动结束时,value才会改变。

设置滑块左边(小于部分)线条的颜色

@property(nonatomic,retain) UIColor *minimumTrackTintColor

设置滑块右边(大于部分)线条的颜色

@property(nonatomic,retain) UIColor *maximumTrackTintColor

设置滑块颜色(影响已划过一端的颜色)

@property(nonatomic,retain) UIColor *thumbTintColor

注意这个属性:如果你没有设置滑块的图片,那个这个属性将只会改变已划过一段线条的颜色,不会改变滑块的颜色,如果你设置了滑块的图片,又设置了这个属性,那么滑块的图片将不显示,滑块的颜色会改变(IOS7)

手动设置滑块的值:

- (void)setValue:(float)value animated:(BOOL)animated;

设置滑块的图片:

- (void)setThumbImage:(UIImage *)image forState:(UIControlState)state;

设置滑块划过部分的线条图案

- (void)setMinimumTrackImage:(UIImage *)image forState:(UIControlState)state;

设置滑块未划过部分的线条图案

- (void)setMaximumTrackImage:(UIImage *)image forState:(UIControlState)state;

对应的几个get方法

- (UIImage *)thumbImageForState:(UIControlState)state;- (UIImage *)minimumTrackImageForState:(UIControlState)state;- (UIImage *)maximumTrackImageForState:(UIControlState)state;

对应的设置当前状态的响应属性的方法

@property(nonatomic,readonly) UIImage* currentThumbImage;@property(nonatomic,readonly) UIImage* currentMinimumTrackImage;@property(nonatomic,readonly) UIImage* currentMaximumTrackImage;

值正在变化

[self.progressSlider addTarget:self action:@selector(sliderProgressChange:) forControlEvents:UIControlEventValueChanged]; 

开始滑动

[self.progressSlider addTarget:self action:@selector(sliderTouchDown:) forControlEvents:UIControlEventTouchDown]; 

滑动结束

[self.progressSlider addTarget:self action:@selector(sliderTouchUpInSide:) forControlEvents:UIControlEventTouchUpInside];
