Try this: let path = CGMutablePath() path.move(to: CGPoint(x: lineFrame.midX, y: lineFrame.midY)) path.addLine(to: CGPoint(x: lineFrame.origin.x + lineFrame.width / 2, y: lineFrame.origin.y)) And check the latest reference of CGMutablePath: CGMutablePath
Since Late 2017 Starting with iOS 11, macOS 10.13, tvOS 11, and watchOS 4, you should use the CGPath‘s applyWithBlock method. Here is a real example taken from this Swift package that rounds the corners of a CGPath. In this code, self is a CGPath: self.applyWithBlock { let points = $0.pointee.points switch $0.pointee.type { case … Read more
I have found a solution for this, we need to create a array of array of DrawingPaths: – (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { // Do the above code, then [m_undoArray addObject:self.currentPath]; } – (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [m_parentUndoArray addObject:[NSArray arrayWithArray:m_undoArray]]; } and then stroke the path in DrawRect.
I am not an expert on CoreAnimation but you can define a CABasicAnimation as follows CABasicAnimation *morph = [CABasicAnimation animationWithKeyPath:@”path”]; morph.duration = 5; morph.toValue = (id) [self getTrianglePath]; [maskLayer addAnimation:morph forKey:nil]; The first line states that you want to define an animation that changes the path property of the layer. The second line states that … Read more
Try this: let path = CGMutablePath() path.move(to: CGPoint(x: 30, y: 0)) CGPath APIs are now imported as instance methods in Swift 3. You can check them with Command-clicking on CGMutablePath. Or see the latest reference of CGMutablePath.
