要求

安装

RichLabel 可通过CocoaPods获得。要安装它,只需将以下行添加到您的 Podfile 中:

pod 'RichLabel'

用法

import RichLabel

let label = RichLabel()
label.numberOfLines = 0
label.enabledTypes = [.mention, .hashtag, .url, .email]
label.text = "This is a post with #hashtags and a @userhandle."
label.textColor = .black
label.handleHashtagTap { hashtag in
    print("Success. You just tapped the \(hashtag) hashtag")
}

自定义类型

let customType = RichType.custom(pattern: "\\swith\\b") //Regex that looks for "with"
label.enabledTypes = [.mention, .hashtag, .url, .email, customType]
label.text = "This is a post with #hashtags and a @userhandle."
label.customColor[customType] = UIColor.purple
label.customSelectedColor[customType] = UIColor.green
label.handleCustomTap(for: customType) { element in
    print("Custom type tapped: \(element)")
}

启用/禁用突出显示

默认情况下,RichLabel 实例具有以下配置

label.enabledTypes = [.mention, .hashtag, .url, .email]

但请随意启用/禁用以满足您的要求

批量定制

在使用RichLabel时,推荐使用customize(block:)自定义的方法。原因是 RichLabel 会对您设置的每个属性做出反应。所以如果你设置了3个属性,textContainer会被刷新3次。

使用 时customize(block:),您可以对标签上的所有自定义进行分组,这样 RichLabel 只会刷新 textContainer 一次。

例子:

label.customize { label in
    label.text = "This is a post with #multiple #hashtags and a @userhandle."
    label.textColor = UIColor(red: 102.0/255, green: 117.0/255, blue: 127.0/255, alpha: 1)
    label.hashtagColor = UIColor(red: 85.0/255, green: 172.0/255, blue: 238.0/255, alpha: 1)
    label.mentionColor = UIColor(red: 238.0/255, green: 85.0/255, blue: 96.0/255, alpha: 1)
    label.URLColor = UIColor(red: 85.0/255, green: 238.0/255, blue: 151.0/255, alpha: 1)
    label.handleMentionTap { self.alert("Mention", message: $0) }
    label.handleHashtagTap { self.alert("Hashtag", message: $0) }
    label.handleURLTap { self.alert("URL", message: $0.absoluteString) }
}

修剪长网址

您可以设置 url 的最大长度;

label.urlMaximumLength = 30

从现在开始,比这更大的 url 将被修剪。
