CAGradientLayer *gradientLayer = [CAGradientLayer layer];
UIColor *color1= LBColor(255, 70, 93);
UIColor *color2 = LBColor(251, 108, 42);
gradientLayer.colors = @[(__bridge id)color1.CGColor, (__bridge id)color2.CGColor];
gradientLayer.locations = @[@0.5, @1.0];
gradientLayer.startPoint = CGPointMake(0, 0);
gradientLayer.endPoint = CGPointMake(1.0, 0);
