Since the question I asked has been seen many times I will provide a detailed answer of it. Feel free to modify it if you want to add more correct content. First a recap on the question: frame, bounds and center and theirs relationships. Frame A view’s frame (CGRect) is the position of its rectangle … Read more
Objective-C: UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 50)]; CAGradientLayer *gradient = [CAGradientLayer layer]; gradient.frame = view.bounds; gradient.colors = @[(id)[UIColor whiteColor].CGColor, (id)[UIColor blackColor].CGColor]; [view.layer insertSublayer:gradient atIndex:0]; Swift: let view = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 50)) let gradient = CAGradientLayer() gradient.frame = view.bounds gradient.colors = [UIColor.white.cgColor, UIColor.black.cgColor] view.layer.insertSublayer(gradient, at: 0) Info: … Read more
Swift // corner radius blueView.layer.cornerRadius = 10 // border blueView.layer.borderWidth = 1.0 blueView.layer.borderColor = UIColor.black.cgColor // shadow blueView.layer.shadowColor = UIColor.black.cgColor blueView.layer.shadowOffset = CGSize(width: 3, height: 3) blueView.layer.shadowOpacity = 0.7 blueView.layer.shadowRadius = 4.0 Exploring the options Problem 1: Shadow gets clipped off What if there are sublayers or subviews (like an image) whose content we want … Read more
I am not sure why your solution did not work but the following code is working for me. Create a bezier mask and apply it to your view. In my code below I was rounding the bottom corners of the _backgroundView with a radius of 3 pixels. self is a custom UITableViewCell: UIBezierPath *maskPath = … Read more
Do you plan to have a squared UIView of width: 100 and Height: 100 centered inside the UIView of an UIViewController? If so, you may try one of the 6 following Auto Layout styles (Swift 5 / iOS 12.2): 1. Using NSLayoutConstraint initializer override func viewDidLoad() { let newView = UIView() newView.backgroundColor = UIColor.red view.addSubview(newView) … Read more
Try this #import <QuartzCore/QuartzCore.h> // not necessary for 10 years now 🙂 … view.layer.cornerRadius = 5; view.layer.masksToBounds = true; Note: If you are trying to apply rounded corners to a UIViewController‘s view, it should not be applied in the view controller’s constructor, but rather in -viewDidLoad, after view is actually instantiated.
The view’s window property is non-nil if a view is currently visible, so check the main view in the view controller: Invoking the view method causes the view to load (if it is not loaded) which is unnecessary and may be undesirable. It would be better to check first to see if it is already … Read more
The bounds of an UIView is the rectangle, expressed as a location (x,y) and size (width,height) relative to its own coordinate system (0,0). The frame of an UIView is the rectangle, expressed as a location (x,y) and size (width,height) relative to the superview it is contained within. So, imagine a view that has a size … Read more
