Question

美好的一天！

我试图让我的视图（在主视图中查看）制作圆角。我这样做，但它不起作用。有任何想法吗？

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
    // Custom initialization
    currenView = [[UIView alloc] init]; 

    UIBezierPath *maskPath;
    maskPath = [UIBezierPath bezierPathWithRoundedRect:currenView.bounds byRoundingCorners:UIRectCornerAllCorners cornerRadii:CGSizeMake(30.0, 30.0)];

    CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
    maskLayer.frame = currenView.bounds;
    maskLayer.path = maskPath.CGPath;
    currenView.layer.mask = maskLayer;


}
return self;

Answer 1

尝试这样的事情：

view.layer.cornerRadius = 5.0;
view.layer.masksToBounds = YES;

for shadow：

view.layer.shadowColor = [UIColor blackColor].CGColor;
view.layer.shadowOffset = CGSizeMake(1.0f, 1.0f);
view.layer.masksToBounds = NO;
view.layer.shadowRadius = 5.0f;

确保导入<QuartzCore/QuartzCore.h>

这是代码。 Alloc初始化视图并发送到此方法以获得四舍五入。你可以选择围绕你想要的任何角落。同时给出阴影笔触颜色。

-(void) setMaskTo:(UIView*)view byRoundingCorners:(UIRectCorner)corners withColor:  (UIColor*) color
{
 UIBezierPath* rounded = [UIBezierPath bezierPathWithRoundedRect:view.bounds  byRoundingCorners:corners cornerRadii:CGSizeMake(9.0, 9.0)];

CAShapeLayer* shape = [[[CAShapeLayer alloc] init] autorelease];
[shape setPath:rounded.CGPath];
shape.strokeColor = [[UIColor grayColor] CGColor];

view.backgroundColor=color;
view.layer.mask = shape;
}

像这样调用方法。

[self setMaskTo:ABCView byRoundingCorners:UIRectCornerAllCorners withColor:[UIColor greenColor]];

Stavash的解决方案似乎是正确的，我已多次使用它。如果您正在寻找替代方案或坚持使用masklayers，请参阅以下答案：https://stackoverflow.com/a/13163693/936957

Answer 4

您的观点没有大小。它的w和h是0.尝试类似的东西，

currentView = [[UIView alloc] initWithFrame:CGRectMake(0,0 200,200)];

然后申请

currentView.layer.cornerRadius = 8.0;
currentView.layer.masksToBounds = YES;
currentView.layer.borderWidth = 1.0;

创建圆角视图
