Question

我正在使用此代码创建一个角落的视图：

-(IBAction)goToSpecificPage:(UIButton *)sender {

 skipButtonBackgroundView = [[UIView alloc] initWithFrame:CGRectMake(self.view.bounds.size.width-400, 0.0f, 400.0f, 55.0f)];

    UIColor *backGroundColor = [UIColor colorWithRed:0.85098039215 green:0.85098039215 blue:0.85098039215 alpha:1];

    skipButtonBackgroundView.backgroundColor = backGroundColor;       

    UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:skipButtonBackgroundView.bounds byRoundingCorners:UIRectCornerBottomLeft                                                      cornerRadii:CGSizeMake(10.0, 10.0)];   

    // Create the shape layer and set its path

    CAShapeLayer *maskLayer = [CAShapeLayer layer];    
    maskLayer.frame = skipButtonBackgroundView.bounds;    
    maskLayer.path = maskPath.CGPath;    
    skipButtonBackgroundView.layer.mask = maskLayer;    
    [self.view addSubview:skipButtonBackgroundView];  // Drop shadow    
}

但我无法放下视线的阴影。

...谢谢

Answer 1

尝试使用您声明UIBeizerPath

的地方

UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:button.bounds byRoundingCorners:UIRectCornerTopLeft | UIRectCornerTopRight cornerRadii:CGSizeMake(7.0, 7.0)];

maskLayer.shadowPath = maskPath.CGPath;

希望它有所帮助...

我不确定你为什么要使用Shape Layer和东西。如果您只需要投影，可以查看此link

中的方法

如果使一个角落圆形，则无法对视图进行DropShadow
