Usage

To use CRGradientLabel, create a CRGradientLabel and add your content.

An example of making a CRGradientLabel:

Swift:

var gradientLabel: CRGradientLabel = CRGradientLabel(frame: CGRectMake(20, 50, 130, 40))
gradientLabel.gradientColors = [UIColor(red: 239 / 255.0, green: 77 / 255.0, blue:182 / 255.0, alpha: 1.0),
UIColor(red: 198 / 255.0, green: 67 / 255.0, blue: 252 / 255.0, alpha: 1.0)]
gradientLabel.textAlignment = NSTextAlignment.Center
gradientLabel.textColor = UIColor.whiteColor()
gradientLabel.text = NSLocalizedString("CRGradientLabel", comment: "")
gradientLabel.font = UIFont.boldSystemFontOfSize(20.0)
self.view.addSubview(gradientLabel)

Objective-C:

CRGradientLabel *gradientLabel = [[CRGradientLabel alloc] initWithFrame:CGRectMake(20, 50, 130, 40)];
gradientLabel.gradientColors = @[[UIColor colorWithRed:239/255.0f green:77/255.0f blue:182/255.0f alpha:1.0f], [UIColor colorWithRed:198/255.0f green:67/255.0f blue:252/255.0f alpha:1.0f]];
gradientLabel.textAlignment = NSTextAlignmentCenter;
gradientLabel.textColor = [UIColor whiteColor];
gradientLabel.text = NSLocalizedString(@"CRGradientLabel", nil);
gradientLabel.font = [UIFont boldSystemFontOfSize:20.0f];
[self.view addSubview:gradientLabel];

Don't forget to set the gradient colors via an array using the gradientColors property:

Swift:

gradientLabel.gradientColors = [UIColor(red: 239 / 255.0, green: 77 / 255.0, blue:182 / 255.0, alpha: 1.0),
UIColor(red: 198 / 255.0, green: 67 / 255.0, blue: 252 / 255.0, alpha: 1.0)]

Objective-C:

gradientLabel.gradientColors = @[[UIColor colorWithRed:255/255.0f green:42/255.0f blue:104/255.0f alpha:1.0f],
[UIColor colorWithRed:255/255.0f green:90/255.0f blue:58/255.0f alpha:1.0f]];
