Am using Xcode 4.5, targeting iOS5 and above. I am updating an app, using Storyboard for all scenes. Have a previous XIB and controller that I converted, but it is not functioning the same way. The controller allows changing the color of text and creating new colors. Creating new RGB colors relies on 3 Horizontal Sliders to change a swatch of color and the corresponding RGB values on 3 separate labels, before saving the new color. The sliders are Value Changed Sent Events and are hooked up to one action. The issue: when I change any of the sliders, ONLY the red label and red color value. I've tried changing the individual cases for the sliders into separate actions, and moving the setPreviewImage into a method of its own, but then, it does not change the swatch. Any help would be greatly appreciated. Thanks in advance.
-(IBAction)RGBSliderChange:(UISlider *)sender {
switch ([sender tag])
{
case 0: {
self.rLabel.text = [NSString stringWithFormat:@"%d", (int)[sender value]];
break;
}
case 1: {
self.gLabel.text = [NSString stringWithFormat:@"%d", (int)[sender value]];
break;
}
case 2: {
self.bLabel.text = [NSString stringWithFormat:@"%d", (int)[sender value]];
break;
}
default:
break;
}
self.colorPreviewImage.backgroundColor = [UIColor colorWithRed:(CGFloat)[self.rLabel.text floatValue]/256
green:(CGFloat)[self.gLabel.text floatValue]/256
blue:(CGFloat)[self.bLabel.text floatValue]/256
alpha:1.0];
}
