1.addtarget 的。部分使用事件没有直接的操作方式，需要进行调用。就要用addTarget。
- (void)setupCustomView {
self.customView = [[CHView alloc] init];
self.customView.translatesAutoresizingMaskIntoConstraints = NO;
[self.view addSubview:self.customView];
NSDictionary *viewsDictionary = @{ @"topLayoutGuide": self.topLayoutGuide,
@"customView": self.customView
};
[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[topLayoutGuide][customView]|"
options:0
metrics:nil
views:viewsDictionary]];
[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[customView]|"
options:0
metrics:nil
views:viewsDictionary]];
[self setupSliders];
[self updateColors];
[self setupTargetActions];
}
- (void)setupSliders {
self.customView.trackWidthSlider.maximumValue = 100.0;
self.customView.gaugeWidthSlider.maximumValue = 100.0;
self.customView.valueSlider.value = self.customView.gauge.value;
self.customView.trackWidthSlider.value = self.customView.gauge.trackWidth;
self.customView.gaugeWidthSlider.value = self.customView.gauge.gaugeWidth;
self.customView.valueSliderLabel.text = [self formattedStringForFloatValue:(self.customView.gauge.value * 100)];
self.customView.trackWidthSliderLabel.text = [self formattedStringForFloatValue:self.customView.gauge.trackWidth];
self.customView.gaugeWidthSliderLabel.text = [self formattedStringForFloatValue:self.customView.gauge.gaugeWidth];
self.customView.valueSlider.continuous = NO;
self.customView.trackWidthSlider.continuous = NO;
self.customView.gaugeWidthSlider.continuous = NO;
