Question

In my iPhone app I m using a slider for adjusting the volume and working fine. But I m not able to set a default value for slider when app loads. I have seen that only when the slider is touched the value gets changed.But i need a default value when app loads. My code is given below

- (IBAction)sliderChanged:(id)sender {

    slider = (UISlider *) sender;
    slider.minimumValue = 0.5;
    slider.maximumValue = 2.2;
    progressAsInt = slider.value ;
}

如何解决这一问题。

请提供帮助。提前感谢。

Answer 1

有两个办法改变电梯的违约价值。

Using Interface builder. See attached picture and value of current property.
《刑法》

鉴于WillAppear代表方法,你只需要写这个字。

-(void)viewWillAppear:(BOOL)animated{
   slider.value = 1.0;
 }

希望这一帮助。

Answer 2

首先,需要将电梯带给一位观察控制器的电梯。

之后,委员会认为各位可以确定你们想要的价值。

(Also, you should be able to do it in Interface Builder, but I m not very familiar with it).
