如何在Swift中使用addAttribute [英] How to use addAttribute in Swift

问题描述

我正在尝试添加到UITextViews的链接，所以我遵循此帖子.相关的Objective-C代码是

I'm trying to add links to UITextViews, so I am following the code in this post. The relevant Objective-C code is

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"This is an example by @marcelofabri_"];
[attributedString addAttribute:NSLinkAttributeName
                         value:@"username://marcelofabri_"
                         range:[[attributedString string] rangeOfString:@"@marcelofabri_"]];

但是当我在Swift 2中尝试这样做

But when I try this in Swift 2 as

var attributedString = NSMutableAttributedString(string: "This is an example by @marcelofabri_")
attributedString.addAttribute(NSLinkAttributeName, value: "username://marcelofabri_", range: attributedString.string.rangeOfString("/marcelofabri_"))

我收到错误

不能使用类型为'(String，value:String，range:Range?)'的参数列表调用'addAttribute'

Cannot invoke 'addAttribute' with an argument list of type '(String, value: String, range: Range?)'

要使它正常工作，我需要更改什么?

What do I need to change to get this to work?

推荐答案

尝试使用 NSString 而不是Swift String 查找范围:

Try using NSString to find range instead of Swift String:

var attributedString = NSMutableAttributedString(string: "This is an example by @marcelofabri_")
attributedString.addAttribute(NSLinkAttributeName, value: "username://marcelofabri_", range: (attributedString.string as NSString).rangeOfString("/marcelofabri_"))
