＆＃39;字符串＆＃34;不能转换为＆＃39; [（String）]＆＃39;

Question

我试图通过＆＃34;，＆＃34;分割从URL返回的字符串。但是当我尝试

时

var tagArray = [String]()
if response.responseObject != nil {
                let data = response.responseObject as NSData
                let str = NSString(data: data, encoding: NSUTF8StringEncoding)!
                self.tagArray = str.componentsSeparatedByString(", ") as String
                println("response: \(self.tagArray)") //prints the HTML of the page
            }

第self.tagArray = str.componentsSeparatedByString(", ") as String行会引发错误＆＃34;＆＃39; String＆＃34;不能转换为＆＃39; [（字符串）]＆＃39;＆＃34;

任何人都知道如何正确地将字符串拆分成数组？

违规行缺少广告投放中的[] - 当您需要投射到{em>数组 String时，您需要投放到Strings {1}}：

var tagArray = [String]()
if response.responseObject != nil {
    let data = response.responseObject as NSData
    let str = NSString(data: data, encoding: NSUTF8StringEncoding)!
    self.tagArray = str.componentsSeparatedByString(", ") as [String]
    println("response: \(self.tagArray)") //prints the HTML of the page
}
