给定圆角半径时 UIButton 边框切割

Question

我创建了具有特定位置圆角半径的 UIButton，这意味着左按钮具有左上角半径和左下角半径，右按钮具有右上角半径和右下角半径我已经在 Xib 中使用按钮并给出边框但我剪掉了从某些方面来说，我附上了下面的截图。

查看右侧边角边框切割。这是我的代码

  [btn_Newest setBackgroundColor:RGB(28.0, 91.0, 161.0, 1.0)];
    [btn_Newest.layer setBorderWidth:1.5];
    [btn_Newest.layer setBorderColor:RGB(28.0, 91.0, 161.0, 1.0).CGColor];
    [btn_Newest setClipsToBounds:YES];
    btn_Newest = (UIButton *)[self setroundCornersOnView:btn_Newest onTopLeft:YES topRight:NO bottomLeft:YES bottomRight:NO radius:7.0];


    [btn_Popular setBackgroundColor:viewTopBar.backgroundColor];
    [btn_Popular.layer setBorderWidth:1.5];
    [btn_Popular.layer setBorderColor:RGB(28.0, 91.0, 161.0, 1.0).CGColor];
    [btn_Popular setClipsToBounds:YES];
    btn_Popular = (UIButton *)[self setroundCornersOnView:btn_Popular onTopLeft:NO topRight:YES bottomLeft:NO bottomRight:YES radius:7.0];

setroundCornersOnView这个函数创建特定的侧角radius.Can任何人在这种情况下帮助我。

Answer 1

而不是设置 setroundCornersOnView 。您可以将 cornerRadius 设置为按钮。试试下面的代码。 [btn_Newest.layer setCornerRadius:5];

Answer 2

请尝试以下代码。我想它会满足你的要求。

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

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

CAShapeLayer *borderLayer = [[CAShapeLayer alloc] init];
borderLayer.frame = self.view.bounds;
borderLayer.path  = maskPath.CGPath;
borderLayer.lineWidth   = 1.5f;
borderLayer.strokeColor = [UIColor blackColor].CGColor;
borderLayer.fillColor   = [UIColor clearColor].CGColor;
[btnPush.layer addSublayer:borderLayer];
