我创建UIView了应用CAGradientLayer色彩效果,因为我附加了Image Bellow.现在在这里我想要像屏幕保护程序一样平滑地改变它的渐变颜色从上到下.我已经尝试使用NStimer那个位Done但它的颜色变化CAGradientLayer看起来像混蛋.

对于上面我使用Bellow方法代码: -

Timer =  [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(TIMER) userInfo:nil repeats:NO];

        gradient.frame = self.view_Color.bounds;

        if (Count == 1)
        {
            gradient.colors = [NSArray arrayWithObjects:(id)[[UIColor greenColor] CGColor], (id)[[UIColor  colorWithRed:44/255.0 green:255/255.0 blue:255/255.0 alpha:1.0f] CGColor], (id)[[UIColor  colorWithRed:0/255.0 green:0/255.0 blue:254/255.0 alpha:1.0f] CGColor], (id)[[UIColor  colorWithRed:252/255.0 green:0/255.0 blue:255/255.0 alpha:1.0f] CGColor], (id)[[UIColor  colorWithRed:252/255.0 green:0/255.0 blue:6/255.0 alpha:1.0f] CGColor], (id)[[UIColor  colorWithRed:253/255.0 green:131/255.0 blue:6/255.0 alpha:1.0f]CGColor], …
