uibezierpath

I've been searching for an answer for hours but have trouble finding anything on the topic. I have a question related to Objective-c. I'm making an application in which a UIView checks for touches from the user and if the user touches and moves his/her finger, a path using UIBezierPath is drawn. If the user draws so that the path intersects itself it should disappear from the screen. When the user is done drawing the pattern, a line from the last point in the path should connect with the first point in the path automatically (I'm using the method "closePath" for this), if this line intersects

My attempt to draw UIBezierPath lines with different colors is failing me. All the lines change to the currently selected color. All my path and information are all stored in an NSMutableArray called pathInfo. In path info I drop in array that contains the Path, Color, Width, and Type of line. This works fine except all the lines turn to whatever color the user has selected. I would appreciate any help greatly! - (void)drawRect:(CGRect)rect { UIBezierPath *drawPath = [UIBezierPath bezierPath]; drawPath.lineCapStyle = kCGLineCapRound; drawPath.miterLimit = 0; for (int i = 0; i < [pathInfo count

I have an app where I take a UIBezierPath and use it as a brush by a series of appendPath: calls. After a few goes and with really complex brush shapes the memory runs out and the app grinds to a halt. What I really want to do is a full on union exactly like Paint Code does but I can't find any way of doing this. How would I go about unioning two or more UIBezierPaths? EDIT: Here is a visual of what I want to achieve dynamically. In Paint Code you take two paths and overlap them like this: BUT I want to merge / union them into one new single path like: Note that in the bottom panel of Paint

I want to round my right corners, but only works for Left corners let path = UIBezierPath(roundedRect: view.bounds, byRoundingCorners: [UIRectCorner.TopLeft, UIRectCorner.TopRight], cornerRadii: CGSizeMake(20.0, 20.0)) let maskLayer = CAShapeLayer() maskLayer.path = path.CGPath view.layer.mask = maskLayer view.layer.masksToBounds = true The problem is that you're getting the view's bounds before it's been resized for the current device. It's larger than it will be later when it appears on screen, so the right side of your rounded rect is off the right side of the screen. You need to create

I want to get the image from the UIBezierpath closed path(See the image). I draw the image on the UIView using drawRect method and also draw the lines are using the drawRect method. How can I get the particular closed path image? Please help me. Thanks in advance. This code used for draw the bezierpath. UIBezierPath *aPath = [UIBezierPath bezierPath]; for (NSString *pointString in pointArray) { if ([pointArray indexOfObject:pointString] == 0) [aPath moveToPoint:CGPointFromString(pointString)]; else [aPath addLineToPoint:CGPointFromString(pointString)]; } [aPath closePath]; iDev You can use a
