How I could show a UISliders value as a U开发者_开发技巧ILabels text?
Add an action to the slider, like this:
[slider addTarget:self action:@selector(sliderChanged:) forControlEvents:UIControlEventValueChanged];
Where the sliderChanged:
method looks something like this:
- (void)sliderChanged:(UISlider *)slider {
self.label.text = [NSString stringWithFormat:@"%g", slider.value];
}
Try this:
- (IBAction) sliderValueChanged:(UISlider *)sender {
label.text = [NSString stringWithFormat:@"%f", slider.value];
}
If label and/or slider are IB elements, define IBOutlets and connect them.
And then connect the slider sliderChanged
action to this method.
Good luck!
//This is for getting the Int Value
- (IBAction)sliderValueChanged:(UISlider *)sender
{
yourtextlabel.text = [NSString stringWithFormat:@"%d", (int)yourslideroutletname.value];
NSLog(@"the selider value==%@",yourtextlabel.text);
}
//This is for getting the float Value
- (IBAction)sliderValueChanged:(UISlider *)sender
{
yourtextlabel.text = [NSString stringWithFormat:@"%f", yourslideroutletname.value];
NSLog(@"the selider value==%@",yourtextlabel.text);
}
