cagradientlayer

I have been trying to figure out for quite a while now about how to add a gradient layer to the tableView, and have tried many different things, but I can never get the table view cells to show, no matter how many bringSubviews or sendSubviews I do. let gradientLayer = CAGradientLayer() gradientLayer.frame = view.bounds gradientLayer.colors = [UIColor(red: 125/255.0, green: 125/255.0, blue: 125/255.0, alpha: 1.0).cgColor, UIColor(red: 125/255.0, green: 125/255.0, blue: 255/255.0, alpha: 1.0).cgColor] gradientLayer.startPoint = CGPoint(x: 0.0, y: 0.0) gradientLayer.endPoint = CGPoint(x: 0.0, y:

I try to make a standard gradient top-bottom with long UIView. But it's not full. The nib is part of UITableViewCell, so I don't have access to viewDidLayoutSubviews() as in this thread . I've tried to call contentView.layoutIfNeeded() from the code version of this view. I called it when UITableView cellForRowAtIndexPath gets called. But it's no effect. I prepare the gradient in awakeFromNib() . let colors = [ UIColor(red: 33/255.0, green: 33/255.0, blue: 33/255.0, alpha: 1.0).cgColor, UIColor(red: 51/255.0, green: 51/255.0, blue: 51/255.0, alpha: 1.0).cgColor] let gradient = CAGradientLayer()

This question already has an answer here : Drawing gradient on UIView not working with iOS 9 (1 answer) Closed 4 years ago . I created a new project. I linked QuartzCore.framework and imported <QuartzCore/QuartzCore.h> in the ViewController.m . And here is the code. - (void)viewDidLoad { [super viewDidLoad]; NSLog(@"view height %f", self.view.frame.size.height); // returns 667 on iPhone 6 NSLog(@"view width %f", self.view.frame.size.width); // returns 375 on iPhone 6 NSLog(@"layers count %lu", self.view.layer.sublayers.count); // returns 2 // Gradient UIColor *colorOne = [UIColor blueColor];

In one of my application, I am trying to draw a gradient arc with rounded edges. Like the following image. This is what I have done so far using the following code. -(void)startArc { UIBezierPath *roundedArc = [self arcWithRoundedCornerAt:centerPoint startAngle:DEGREES_TO_RADIANS(-90) endAngle:DEGREES_TO_RADIANS(90) innerRadius:width-20 outerRadius:width cornerRadius:0]; CAShapeLayer *mask = [CAShapeLayer new]; [mask setPath:roundedArc.CGPath]; [mask setFrame:_outerView.bounds]; [mask setShouldRasterize:YES]; [mask setRasterizationScale:[UIScreen mainScreen].scale]; CAGradientLayer *gradient =
