如何在NSSlider上获得完成的操作？

Question

这里有一个NSSlider，代码如下

- (IBAction)sliderChanged:(id)sender {
NSSlider *slider = sender;
NSInteger value = slider.integerValue;
NSLog(@"%ld",value);
}

因为我设置了slider.continuous = YES;，NSLog将实时打印，这是正确的，我需要添加更多，除了上面的功能，我想在更改完成时获得值，有什么想法吗？非常感谢。

UISlider是UIControl的子类，您可以为event UIControlEventTouchUpInside添加目标及其操作。xib1

- (IBAction)sliderChanged:(id)sender{
UISlider *slider = sender;
NSLog(@"sliderChanged Value = %ld",(long)slider.value);
}

- (IBAction)sliderFinished:(id)sender{
UISlider *slider = sender;
NSLog(@"sliderFinished Value = %ld",(long)slider.value);
}
