我如何描邊和填充NSAttributedString瓦特/的UILabel

Question

是否可以同時適用行程和填寫與NSAttributedString和UILabel？

Answer 1

沒錯，關鍵是一個負值應用於NSStrokeWidthAttributeName 如果這個值是正數，你將只能看到行程，而不是填充。

目的-C：

self.label.attributedText=[[NSAttributedString alloc] 
initWithString:@"string to both stroke and fill" 
attributes:@{ 
      NSStrokeWidthAttributeName: @-3.0, 
      NSStrokeColorAttributeName:[UIColor yellowColor], 
      NSForegroundColorAttributeName:[UIColor redColor] 
      } 
]; 

由於下面@cacau：參見Technical Q&A QA1531

夫特版本：

let attributes = [NSStrokeWidthAttributeName: -3.0, 
         NSStrokeColorAttributeName: UIColor.yellowColor(), 
         NSForegroundColorAttributeName: UIColor.redColor()]; 

label.attributedText = NSAttributedString(string: "string to both stroke and fill", attributes: attributes) 

夫特3版本：

let attributes = [NSStrokeWidthAttributeName: -3.0, 
         NSStrokeColorAttributeName: UIColor.yellow, 
         NSForegroundColorAttributeName: UIColor.red] as [String : Any] 

    label.attributedText = NSAttributedString(string: "string to both stroke and fill", attributes: attributes)

斯威夫特版本：

let attributes = [NSStrokeWidthAttributeName: -3.0, 
         NSStrokeColorAttributeName: UIColor.yellowColor(), 
         NSForegroundColorAttributeName: UIColor.redColor()]; 

label.attributedText = NSAttributedString(string: "string to both stroke and fill", attributes: attributes) 

斯威夫特3版本：

let attributes = [NSStrokeWidthAttributeName: -3.0, 
         NSStrokeColorAttributeName: UIColor.yellow, 
         NSForegroundColorAttributeName: UIColor.red] as [String : Any] 

    label.attributedText = NSAttributedString(string: "string to both stroke and fill", attributes: attributes) 

Answer 3

現在迅速蘋果最新 刪除[字符串：任何]的屬性鍵值聲明用作[NSAttributedStringKey：任何]

let strokeTextAttributes = [ 
     NSAttributedStringKey.strokeColor : UIColor.green, 
     NSAttributedStringKey.foregroundColor : UIColor.lightGray, 
     NSAttributedStringKey.strokeWidth : -4.0, 
     NSAttributedStringKey.font : UIFont.boldSystemFont(ofSize: 52) 
     ] as [NSAttributedStringKey : Any] 

    hello_cell_lb.attributedText = NSAttributedString(string: "\(hello_array[indexPath.row])", attributes: strokeTextAttributes) 

謝謝
