  • [翻译] CKShapeView 支持CAShapeLayer

    CKShapeView 支持CAShapeLayer

    https://github.com/conradev/CKShapeView

    CKShapeView is a UIView subclass that is backed by a CAShapeLayer.

    In other words, it is a view that is capable of rendering an arbitrary CGPath.

    It is completely configurable and animatable, so you can have custom drawn views without needing to subclass.

    CKShapeView has all of the properties of CAShapeLayer, with the addition of a hitTestUsingPath property that allows you to hit test using the path instead of the view's bounds.

    CKShapeView是一个UIView的子类,它支持CAShapeLayer。

    换句话说,它是一个view,可以用来渲染CGPath。

    我完全配置了它并可以动画化,所以,你可以直接定制这个view而不需要继承至它的子类。

    CKShapeView有着CAShapeLayer的所有属性,我添加了一个额外的属性hitTestUsingPath,允许你使用路径来做点击测试而不是这个view的bounds。

    Example Usage

    CKShapeView *pieView = [[CKShapeView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
    CGFloat width = CGRectGetWidth(pieView.bounds);
    pieView.path = [UIBezierPath bezierPathWithOvalInRect:CGRectInset(pieView.bounds, width/4, width/4)];
    pieView.lineWidth = width/2;
    pieView.fillColor = nil;
    pieView.strokeColor = [UIColor blackColor];
    [self.view addSubview:pieView];
    
    UIViewAnimationOptions options = UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat;
    [UIView animateWithDuration:1.0f delay:0.0f options:options animations:^{
        pieView.strokeEnd = 0.0f;
    } completion:nil];
