数组从字典键swift [英] Array from dictionary keys in swift

问题描述

  var componentArray：[String] 
 
 let dict = NSDictionary（contentsOfFile：NSBundle.mainBundle（）。pathForResource（Components，ofType：plist）！）
 componentArray = dict.allKeys 
  

这会返回一个错误：'AnyObject'与字符串不相同

还试过

  componentArray = dict.allKeys as String 
  

但得到：'String'不能转换为[String]

解决方案

Swift 3

  componentArray = Array（dict.keys）// for Dictionary 
 
 componentArray = dict。 allKeys // for NSDictionary 
  

Trying to fill an array with strings from the keys in a dictionary in swift.

var componentArray: [String]

let dict = NSDictionary(contentsOfFile: NSBundle.mainBundle().pathForResource("Components", ofType: "plist")!)
componentArray = dict.allKeys

This returns an error of: 'AnyObject' not identical to string

Also tried

componentArray = dict.allKeys as String 

but get: 'String' is not convertible to [String]

解决方案

Swift 3

componentArray = Array(dict.keys) // for Dictionary

componentArray = dict.allKeys // for NSDictionary
