我正在尝试使按钮的两个角变圆。如果我像这样选择.TopLeft和.BottomLeft:letbezierDisableAdsPath=UIBezierPath(roundedRect:disableAdsButton.bounds,byRoundingCorners:[UIRectCorner.TopLeft,UIRectCorner.BottomLeft],cornerRadii:CGSizeMake(4.0,4.0))letmaskAdsLayer=CAShapeLayer()maskAdsLayer.frame=disableAdsButton.boundsmaskAdsLay

我想不通...我在玩-[UIBezierPathbezierPathWithRoundedRect:byRoundingCorners:cornerRadii:]这样:bezierPath=[UIBezierPathbezierPathWithRoundedRect:CGRectMake(10,10,80,80)byRoundingCorners:(UIRectCornerBottomLeft)cornerRadii:CGSizeMake(20,20)];它按预期工作。但是，如果我将cornerRadii:CGSizeMake(20,20)替换为cornerRadii:CGSizeMa

我正在使用此代码使按钮的两个角变圆。letbuttonPath=UIBezierPath(roundedRect:button.bounds,byRoundingCorners:.TopLeft|.BottomLeft,cornerRadii:CGSizeMake(1.0,1.0))它抛出一个错误:binaryoperator'|'cannotbeappliedtotwoUIRectCorneroperands.如何在Swift2.0中使用此方法？ 最佳答案 swift2:letbuttonPath=UIBezierPath(rou
