从转换为字符串的数组值中删除括号

Remove parentheses from array value converted to string

我有一个文本视图,当显示文本时,文本中有括号。我想消灭他们。这是我的代码:

self.txtpstn.text =  "\(self.no_pstn.self as NSArray)"
self.txtmobile.text =  "\(self.no_mobile.self as NSArray)"

这是应用程序上的显示:

使用连接:

self.txtpstn.text =  "\((self.no_pstn.self as NSArray).componentsJoined(by: ","))"
self.txtmobile.text =  "\(self.no_mobile.self as NSArray).componentsJoined(by: ","))"
