栈顶的方法是：

- (void)orangeGradient: (UILabel *)fillLabel {
@synchronized([CommonClass class]) {
CAGradientLayer * gradientLayer = [CAGradientLayer layer];
gradientLayer.frame = fillLabel.bounds;
gradientLayer.colors = [NSArray arrayWithObjects:(id)[UIColorFromRGB(0xfbb250) CGColor],(id)[UIColorFromRGB(0xf47c2a) CGColor], nil];
[fillLabel.layer addSublayer:gradientLayer];
}
}

请高手指点，谢谢
