用UISliders值更改UILabels文本

Question

嘿，我想知道如何將UISliders值顯示爲UILabels文本。由於

Answer 1

添加操作的滑塊，這樣的：

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

凡sliderChanged:方法看起來是這樣的：

- (void)sliderChanged:(UISlider *)slider { 
    self.label.text = [NSString stringWithFormat:@"%g", slider.value]; 
} 

Answer 2

試試這個：

- (IBAction) sliderValueChanged:(UISlider *)sender { 
    label.text = [NSString stringWithFormat:@"%f", slider.value]; 
} 

如果標籤和/或滑塊是IB元素，定義IBOutlets和連接它們。

然後將滑塊sliderChanged操作連接到此方法。

祝你好運！

//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); 
}
