UISlider

目的：取得Slid的值


Step1.View上拖拉Slid及Label控件

Step2.ViewControl.h
@interface ViewController : UIViewController
{
    IBOutlet UILabel *msg;
}

-(IBAction)changedSlidValue:(UISlider *)sender;

@end

Step3.建立關聯

Step4.ViewControl.m
-(IBAction)changedSlidValue:(UISlider *)sender {
    int slidValue = sender.value;
    NSString *value = [[NSString alloc] initWithFormat:@"%d", slidValue];
    [msg setText:value];
}
