Question

我试图在uitextfield效果上添加角半径，但不是锐角。

请查看附图。

我期待这样的结果。

这是我的灰色文本域代码。

 self.layer.cornerRadius = 7.5
 self.layer.borderWidth = 1.5
 self.layer.borderColor =  UIColor(red: 209/255.0, green: 209/255.0, blue: 209/255.0, alpha: 1.0).CGColor 
 self.backgroundColor = UIColor.whiteColor()

这是我的红色文本域代码。

 self.layer.cornerRadius = 7.5
 self.layer.borderWidth = 1.5
 self.layer.borderColor = TextFieldRedBorderColor.CGColor
 self.backgroundColor = TextFieldRedBackgroundColor

两个代码之间只有颜色差异，但它仍无效。

Answer 1

self.layer.masksToBounds = true

这将解决您的问题

Answer 2

 @IBOutlet var passwordboarderview: UIView!
 @IBOutlet var textusername: UITextField!
 @IBOutlet var txtpassword: UITextField!

 passwordboarderview.layer.cornerRadius = 7.5
 passwordboarderview.layer.borderColor = UIColor.whiteColor().CGColor
 passwordboarderview.layer.borderWidth = 2.0

 passwordboarderview.clipsToBounds = true
 txtpassword.attributedPlaceholder = NSAttributedString(string:"Password",attributes:[NSForegroundColorAttributeName: UIColor.whiteColor()])   

 let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
 textusername.leftView = paddingView
 textusername.leftViewMode = .Always
 textusername.layer.borderWidth = 2.0
 textusername.layer.cornerRadius = 7.5
 textusername.layer.borderColor = UIColor.grayColor().CGColor
 textusername.clipsToBounds = true

我的代码中只有一个错误。

TextField边框样式为行

textField.borderStyle = .Line

然后我将其设为无

textField.borderStyle = .None

它就像我想要的那样工作（圆角）...

无论如何..感谢您的支持和回答......
