使用刪除線文字建立一個字串

Objective-C

NSMutableAttributedString *attributeString = [[NSMutableAttributedString alloc] initWithString:@"Your String here"];
[attributeString addAttribute:NSStrikethroughStyleAttributeName
                    value:@2
                    range:NSMakeRange(0, [attributeString length])];

迅速

let attributeString: NSMutableAttributedString =  NSMutableAttributedString(string: "Your String here")
attributeString.addAttribute(NSStrikethroughStyleAttributeName, value: 2, range: NSMakeRange(0, attributeString.length))

然後你可以將它新增到你的 UILabel：

yourLabel.attributedText = attributeString;
