iOS 瑣碎點------切某個或某幾個角的圓角

標籤：

 

不說廢話---------->

1.如果是切四個角的圓角,程式碼範例:

self.picImage.layer.cornerRadius = 8;

self.picImage.layer.masksToBounds = YES;

 

2.如果是四個角中的某幾個角,一個,兩個,或者3個,程式碼範例(切的左下,和右下):

UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:self.tipLabel.bounds byRoundingCorners:UIRectCornerBottomLeft | UIRectCornerBottomRight cornerRadii:CGSizeMake(5, 5)];

CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];

maskLayer.frame = _tipLabel.bounds;

maskLayer.path = maskPath.CGPath;

self.tipLabel.layer.mask = maskLayer;

 ==================================

類型共有以下幾種:

* UIRectCornerTopLeft

* UIRectCornerTopRight

* UIRectCornerBottomLeft

* UIRectCornerBottomRight

* UIRectCornerAllCorners
