How to crop the image using UIBezierPath?

Question

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 als

Answer 1

For Swift try this : ZImageCropper

ZImageCropper is using following things as core part:

• UIBezierPath
• UITouch Events
• CAShapeLayer
• CoreGraphics

Answer 2

use this pod ios-helpers

- (UIImage *)imageWithStrokeColor: (UIColor *)stroke_color andFillColor: (UIColor *)fill_color {

    // adjust bounds to account for extra space needed for lineWidth
    CGFloat width = self.bounds.size.width + self.lineWidth * 2;
    CGFloat height = self.bounds.size.height + self.lineWidth * 2;
    CGRect bounds = CGRectMake(self.bounds.origin.x, self.bounds.origin.y, width, height);

    // create a view to draw the path in
    UIView *view = [[UIView alloc] initWithFrame:bounds];

    // begin graphics context for drawing
    UIGraphicsBeginImageContextWithOptions(view.frame.size, NO, [[UIScreen mainScreen] scale]);

    // configure the view to render in the graphics context
    [view.layer renderInContext:UIGraphicsGetCurrentContext()];

    // get reference to the graphics context
    CGContextRef context = UIGraphicsGetCurrentContext();

    // reverse the y-axis to match the opengl coordinate space
    CGContextScaleCTM(context, 1, -1);
    CGContextTranslateCTM(context, 0, -view.bounds.size.height);

    // translate matrix so that path will be centered in bounds
    CGContextTranslateCTM(context, -(bounds.origin.x - self.lineWidth), -(bounds.origin.y - self.lineWidth));

    // stroke color
    [stroke_color setStroke];
    [self stroke];

    //fill color
    [fill_color setFill];
    [self fill];

    // get an image of the graphics context
    UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();

    // end the context
    UIGraphicsEndImageContext();

    return viewImage;
