cagradientlayer

I'm using CAGradientLayer on my image. I use this code to do this: UIImage *image = [UIImage imageNamed:@"perfect.jpg"]; [testImage setImage:image]; CAGradientLayer *myLayer = [CAGradientLayer layer]; myLayer.anchorPoint = CGPointZero; //starts in bottom left myLayer.startPoint = CGPointMake(1.0f,1.0f); //ends in top right myLayer.endPoint = CGPointMake(1.0f, 0.0f); UIColor *outerColor = [UIColor colorWithWhite:1.0 alpha:0.0]; UIColor *innerColor = [UIColor colorWithWhite:1.0 alpha:1.0]; //an array of colors that dictatates the gradient(s) myLayer.colors = @[(id)outerColor.CGColor, (id

For an app I had to create a UIButton filled with a gradient and a background image. Everything worked fine until I upgraded the OS from iOS 5.1 to the recently released iOS 6. Here are two screenshots from the simulator : Well, the first screenshot shows what I need (and did), you can see a brown background and the grey radient. Below is the screenshot with the same buttons but with iOS 6 running. As you can see the gradient has vanished and a strange white strip has appeared at the bottom of the UIButton . I've looked if this is a bug or something but I've found nothing, maybe someone here

I have a CAGradientLayer inserted to the bottom of this small detail view that pops up at the bottom of the app. As you can see, I've set the colors from white to clear, but there's this strange gray tint that is showing up. Any ideas? // Set up detail view frame and gradient [self.detailView setFrame:CGRectMake(0, 568, 320, 55)]; CAGradientLayer *layer = [CAGradientLayer layer]; layer.frame = self.detailView.bounds; layer.colors = [NSArray arrayWithObjects:(id)[UIColor whiteColor].CGColor, (id)[UIColor clearColor].CGColor, nil]; layer.startPoint = CGPointMake(1.0f, 0.7f); layer.endPoint =

This question already has an answer here: How to Apply Gradient to background view of iOS Swift App 25 answers used below code for adding gradient layer for a view. After adding gradient layer to a view if i tried to add new subviews inside my gradient view the new view are not getting displayed func setGradientBackground(_ view: UIView ,colorStart:CGColor ,colorEnd:CGColor,cornerRadius:CGFloat) { let gradientLayer = CAGradientLayer() gradientLayer.colors = [colorStart, colorEnd] gradientLayer.startPoint = CGPoint(x: 0.0, y: 0.5); gradientLayer.endPoint = CGPoint(x: 1.0, y: 0.5); gradientLayer

On tableView's cells, I'm trying to define a gradient with the following Swift code: func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { var cell:UITableViewCell = self.tableView?.dequeueReusableCellWithIdentifier("cell") as UITableViewCell cell.backgroundColor=UIColor.clearColor() let gradient : CAGradientLayer = CAGradientLayer() var arrayColors:Array<AnyObject> = [UIColor.blackColor().CGColor, UIColor.whiteColor().CGColor] gradient.colors=arrayColors gradient.frame = cell.bounds cell.layer.insertSublayer(gradient, atIndex: UInt32

I'm building an iOS application in which I have to implement a custom UISlider. The problem is that the built-in UISlider doesn't support gradient track. Another issue is my UI style guide shows that the current tracking value rectangle should be a gradient of two colors as shown in the image How can I build a customized version of the UISlider? I have thought of either subclassing the existing one or by building a UIControl subclass. I'm using xcode 9.4 and swift 4.2 Thanks in advance! I ended up solving the problem by setting the gradient layer as an image for the slider minimum track image

I know how to do (1) but how can I do (2)? UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 50)]; CAGradientLayer *gradient = [CAGradientLayer layer]; gradient.frame = view.bounds; gradient.colors = @[(id)[UIColor blueColor].CGColor, (id)[UIColor redColor].CGColor]; [view.layer insertSublayer:gradient atIndex:0]; There are several ways you could do this. Here's one way: Create a UIView subclass named GradientView to manage the gradient layer. This is helpful because it means you can use the normal UIKit techniques to manage the gradient layout (auto layout constraints,
