Swift-如何使UILabel像主题标签一样可点击并区分相同的文本？ [英] Swift - How to make UILabel clickable like hashtag and distinguish the same text?

问题描述

我有一个UIlabel，其文本类似于以下

I have a UIlabel and it's text like following

label.text = "#fun #fun #google #youtube"

我想使UILabel可单击并打开其网址。

I want to make the UILabel clickable and open it's url.

我也制作字典来设置它的键和值。

I also make the dictionary to set it's keys&values.

var dic:[String:String] = ["https://www.yahoo.com.tw/"   :"fun",
                           "https://www.facebook.com.tw/":"fun",
                           "https://www.google.com.tw/"  :"Google",
                           "https://www.youtube.com/"    :"Youtube"
                          ]  
//How about change it's type to array?
var arr:[[String:String]] = [["https://www.yahoo.com.tw/"   :"fun"],
                             ["https://www.facebook.com.tw/":"fun"],
                             ["https://www.google.com.tw/"  :"Google"],
                             ["https://www.youtube.com/"    :"Youtube"]
                            ] 

如何将乐趣分隔为加载不同的url当我单击 #fun吗？

How to seprate "fun" to load different url When I click "#fun"?

我使用第三库 ActiveLabel.swift 来实现UILabel可点击。 / p>

I use third-library ActiveLabel.swift to achieve UILabel clickable.

label.handleHashtagTap({ (string) in 
    //do something.

    let keys = self.dic.allKeys(forValue: "#\(string) ")        
    print("--> keys: \(keys)")

})

extension Dictionary where Value: Equatable {
    func allKeys(forValue val: Value) -> [Key] {
        return self.filter { $1 == val }.map { $0.0 }
    }
}

推荐答案

使用字典数组，然后执行类似的操作

Use array of dictionary and then do something like this

let dataArray = [["https://www.yahoo.com.tw/"   :"fun"],
                         ["https://www.facebook.com.tw/":"fun"],
                         ["https://www.google.com.tw/"  :"Google"],
                         ["https://www.youtube.com/"    :"Youtube"]
                        ] 

您可以运行for循环以显示所有值您的标签：

And you can run a for loop to show all the values on your label :

for i in 0..<dataArray.count{
    let label = UILabel()
    label.tag = i
    for (key,value) in dataArray[i]{
        print(key, value)
        label.text = "#\(value)"
    }
    // then add tap gesture to that label
}

您必须动态创建标签d每个标签都会有一个轻击手势。

You have to create labels dynamically and each label will have a tap gesture.

在轻击手势上，您可以获得标签的标签，因此可以根据标签从dataArray中获取被点击的值

On tap gesture you can get the tag of the label and thus you can get the tapped value from your dataArray based on your tag.
