I have a UIView with rounded corners along TopLeft and Bottom Right corner sides implement using this code.
CGFloat cornerRadius = _emailContainerView.frame.size.height/2;
CGRect bounds = _emailContainerView.bounds;
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:bounds
byRoundingCorners:(UIRectCornerTopLeft | UIRectCornerBottomRight)
cornerRadii:CGSizeMake(cornerRadius, cornerRadius)];
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = bounds;
maskLayer.path = maskPath.CGPath;
_emailContainerView.layer.mask = maskLayer;
But whenever i tried to draw a border either on the _emailContainerView.layer.borderWidth it shows the border but not along the cutting edges. It just remover the border from the rounded corner sides.
I want to draw the border right along the cutting edges is their any simple way to do that?

The Problem I facing right now is that after I draw the dots and lines by CAShapeLayer, I need to modify both of their colors by changing with different for rect regions. The regions I set right now have four portions, and following are the sample codes:
- (void)drawChartWithRecord:(Chart *)Chart
lineWidth:(CGFloat)lineWidth
radius:(CGFloat)radius
interval:(CGFloat)interval
rect:(CGRect)rect {
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSaveGState(context);
float start_angle = 0;
float end_angle = (float) (2 * M_PI);
CAShapeLayer *avg = [CAShapeLayer layer];
avg.path = [UIBezierPath bezierPathWithArcCenter:CGPointMake(X,Y) radius:radius startAngle:start_angle endAngle:end_angle clockwise:YES].CGPath;
CGContextMoveToPoint(context, X, Y);
CGContextAddLineToPoint(context, pastX, pastY);
CGContextSetStrokeColorWithColor(context, LINE_COLOR);
CGContextSetLineWidth(context, lineWidth);
CGContextStrokePath(context);
[self.layer addSublayer:avg];
}
Upon with the line and dots codes; however, I didn't find out any method to import the rect to the same CAShapeLayer. If I make a new layer as
CAShapeLayer *mask = [CAShapeLayer layer];
There would be a problem that If I use
[self.layer addSublayer:mask];
Two of the sublayers would mix, and I don't want to change my background color.
Thanks for everyone's help : )
Unfortunately, I was wrong about my question.
The thing I want could be easy to solve by the CAGradientLayer & CAShapeLayer. Once you finish your own CAShapeLayer, by using
[self.gradientLayer setMask:avgCircle];
you can easily add the the your own gradient color to the line shape CAShapeLayer
Be sure add addSublayer: for both CAGradientLayer & CAShapeLayer
I have made a hexagonal View with border. The problem I am facing now is I am not able to set the desired color for border which I have made using strokeWidth (not borderWidth) and now my layer's strokeColor get mix with fill color of the layer.
Here is the code:
CAShapeLayer *hexagonMask = [CAShapeLayer layer];
CAShapeLayer *hexagonBorder = [CAShapeLayer layer];
hexagonMask.frame=self.layer.bounds;
hexagonBorder.frame = self.layer.bounds;
UIBezierPath* hexagonPath=[self makeHexagonalMaskPathWithSquareSide:side]; //making hexagon path
hexagonMask.path = hexagonPath.CGPath; //setting the mask path for hexagon
hexagonBorder.path = hexagonPath.CGPath; //setting the maskpath for hexagon border
hexagonBorder.fillColor=[UIColor clearColor].CGColor; //setting by default color
hexagonBorder.lineWidth = self.customBorderWidth; // setting border width
hexagonBorder.strokeColor = self.customBorderColor.CGColor; //setting color for hexagon border
hexagonBorder.fillColor = self.customFillColor.CGColor; //setting fill color for hexagon
Any suggestions to solve this Problem?
Finally I found a way out to solve this problem.
I have added a CALayer as sublayer and the fill color is used to create as a UIImage which is used to set as contents for the sublayer.
Here is the code for someone who may face this problem in future
CAShapeLayer *hexagonMask = [CAShapeLayer layer];
CAShapeLayer *hexagonBorder = [CAShapeLayer layer];
hexagonMask.frame=self.layer.bounds;
hexagonBorder.frame = self.layer.bounds;
UIBezierPath* hexagonPath=[self makeHexagonalMaskPathWithSquareSide:side]; //making hexagon path
hexagonMask.path = hexagonPath.CGPath; //setting the mask path for hexagon
hexagonBorder.path = hexagonPath.CGPath; //setting the maskpath for hexagon border
hexagonBorder.fillColor=[UIColor clearColor].CGColor; //setting by default color
hexagonBorder.lineWidth = self.customBorderWidth; // setting border width
hexagonBorder.strokeColor = self.customBorderColor.CGColor; //setting color for hexagon border
CGFloat coverImageSide=side-(_customBorderWidth);
CGFloat backgroundLayerXY=_customBorderWidth/2.0;
UIImage *coverImage=[UIImage ImageWithColor:_customFillColor width:coverImageSide height:coverImageSide];
UIBezierPath* dpath=[self makeHexagonalMaskPathWithSquareSide:coverImageSide];
CALayer *backgroundLayer=[CALayer layer];
backgroundLayer.frame=CGRectMake(backgroundLayerXY, backgroundLayerXY, coverImageSide, coverImageSide);
CAShapeLayer *backgroundMaskLayer=[CAShapeLayer layer];
backgroundMaskLayer.path=dpath.CGPath;
backgroundLayer.mask=backgroundMaskLayer;
[backgroundLayer setContentsScale:[UIScreen mainScreen].scale];
[backgroundLayer setContentsGravity:kCAGravityResizeAspectFill];
[backgroundLayer setContents:(__bridge id)[UIImage maskImage:coverImage toPath:dpath].CGImage];
[self.layer.sublayers[0] addSublayer:backgroundLayer];
I used a CAShapeLayer to create a mask, which I gave round corners at the top left/right then applied it to my navigationController's navigationBar.
It works like a charm, but I've now noticed I can't use buttons on the navigation bar!
Here's the code I use (in viewDidLoad):
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:self.navigationController.navigationBar.bounds
byRoundingCorners:UIRectCornerTopLeft | UIRectCornerTopRight
cornerRadii:CGSizeMake(6.0, 6.0)];
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = self.navigationController.navigationBar.bounds;
maskLayer.path = maskPath.CGPath;
self.navigationController.navigationBar.layer.mask = maskLayer;
You would need to set the buttons programmatically after setting the layer mask.
I have drawn a circle using bezier curve, I am using this circle as a mask to a uiimage view. Now, how can i move the image inside the circle without moving the circle using touches.
here is my code.
CAShapeLayer *maskLayer = [CAShapeLayer layer];
aPath = [UIBezierPath bezierPathWithArcCenter:CGPointMake(220, 220)
radius:170
startAngle:0
endAngle:DEGREES_TO_RADIANS(360)
clockwise:YES];
maskLayer.backgroundColor = [[UIColor clearColor] CGColor];
maskLayer.path = [aPath CGPath];
maskLayer.masksToBounds=YES;
imageView1.layer.mask = maskLayer;
[self.view addSubview:imageView1];
The coordinates of the mask is the same as the coordinates of your views layer = it moves along with the view.
You can add the image inside another view and mask that view instead. Then you can move the image inside the other view and the mask will stay the same.
Alternatively (but really the same solution) you could keep the mask on that layer and add a sublayer with the image and move that instead.
I have a UITableViewCell, and I want to use the image property to fill it with an image. When it is first in a grouped UITableView, I want it to have the standard rounded corners.
Unfortnately, the image fills the rounded corners as well.. Is there any way to retain them without using a transparent image?
You can round the corners of any view programmatically by using its layer property. If you play about with the cornerRadius property of the layer you should be able to achieve the results you want.
#include <QuartzCore/QuartzCore.h>
UIImage *myImage = [UIImage imageNamed:#"image.png"];
UIImageView *imgView = [[UIImageView alloc] initWithImage:myImage];
imgView.layer.cornerRadius = 10.0;
If you just want to round some of the corners, you should look at the UIBezierPath API and use the path to mask your image. This isn't tested but it should point you in the right direction:
UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:cell.bounds
byRoundingCorners:UIRectCornerTopLeft | UIRectCornerTopRight
cornerRadii:CGSizeMake(10.0, 10.0)];
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = imageView.frame;
maskLayer.path = path;
imageView.layer.mask = maskLayer;
I just made my non-transparent images have the rounded corner. Take a screen shot to get the dimensions of the rounded corner then use that as the basis for your image.
