ios - 设置和获取 slider 值

Question

我这样声明 slider Action

         [self.slider addTarget:self.delegate action:@selector(sliderChanged:) forControlEvents:UIControlEventValueChanged];

现在，在委托(delegate)中，我想更改值。

- (void)sliderChanged:(id)sender
{
UIView *senderView = [sender view]; 
NSLog(@"Slider Changed: %f", slider.value);

我看不到

尝试使用

- (void)sliderChanged:(UISlider *)sender
{

NSLog(@"Slider Changed: %f", sender.value);
}
