圆角

Question

我用下面的方法来得到我的应用程序视图圆角：

(objective-c:) 
hoursTable.layer.cornerRadius = 5.0; 
[hoursTable setClipsToBounds:YES]; 

(my actual code is in rubymotion:) 
self.view.layer.cornerRadius = 10 
self.view.layer.masksToBounds = true 

现在，鉴于所有的边角圆润与10PT，我怎么只适用效果在左上角和右上角，并将左下角和右下角平方？

Answer 1

尝试创建路径手动

CAShapeLayer* shape = [CAShapeLayer layer]; 
CGMutablePathRef path = CGPathCreateMutable(); 
/*...*/ 
CGPathMoveToPoint(path, NULL, 0, 0); 
/*create path for view*/ 

shape.path = path; 
CGPathRelease(path); 
view.layer.mask = shape; 

Answer 2

我有UIView的类别与此代码：

- (void)setRoundedCorners:(UIRectCorner)corners radius:(CGSize)size { 
UIBezierPath* maskPath = [UIBezierPath bezierPathWithRoundedRect:self.bounds byRoundingCorners:corners cornerRadii:size]; 

CAShapeLayer* maskLayer = [[CAShapeLayer alloc] init]; 
maskLayer.frame = self.bounds; 
maskLayer.path = maskPath.CGPath; 

self.layer.mask = maskLayer; 
[maskLayer release]; 
} 

删除最后一个行，如果你使用ARC。使用的

实施例：

[hoursTable setRoundedCorners:UIRectCornerTopLeft|UIRectCornerTopRight radius:CGSizeMake(5.0, 5.0)];
