我想为CAGradientLayer
创建一个颜色渐变,用于不同大小的多个视图。我不知道如何单独定义框架:
UIColor *darkOp = [UIColor colorWithRed:0.2f green:0.2f blue:0.27f alpha:1.0];
UIColor *lightOp = [UIColor colorWithRed:0.36f green:0.35f blue:0.42f alpha:1.0];
// Create the gradient
CAGradientLayer *gradient = [CAGradientLayer layer];
// Set colors
gradient.colors = [NSArray arrayWithObjects:
(id)darkOp.CGColor,
(id)lightOp.CGColor,
nil];
//set radius
gradient.cornerRadius = 5.0;
// Set bounds BUT just for one view size
gradient.frame = self.numberRegionView.bounds; //<-- here I can just define one frame size
// Add the gradient to one view
[self.numberRegionView.layer insertSublayer:gradient atIndex:0];
//but how to add the gradient layer to views with different sizes ???
//[self.graphRegionView.layer insertSublayer:gradient atIndex:0]; ???
//[self.barRegionView.layer insertSublayer:gradient atIndex:0]; ???
谢谢!
答案 0 :(得分:1)
-(void)setGradientForView:(UIView*)view
{
static UIColor *darkOp = [UIColor colorWithRed:0.2f green:0.2f blue:0.27f alpha:1.0];
static UIColor *lightOp = [UIColor colorWithRed:0.36f green:0.35f blue:0.42f alpha:1.0];
// Create the gradient
CAGradientLayer *gradient = [CAGradientLayer layer];
// Set colors
gradient.colors = [NSArray arrayWithObjects:
(id)darkOp.CGColor,
(id)lightOp.CGColor,
nil];
//set radius
gradient.cornerRadius = 5.0;
// Set bounds BUT just for one view size
gradient.frame = view.bounds; //<-- here I can just define one frame size
// Add the gradient to one view
[view.layer insertSublayer:gradient atIndex:0];
}
然后将此代码用于三个视图:
[self setGradientForView:self.numberRegionView];
[self setGradientForView:self.barRegionView];
[self setGradientForView:self.numberRegionView];
