如何阻止我的数组返回多个数组？

Question

我正在尝试从 Youtube API 获取信息，但无法将项目投射到我的数组中。这是我得到的。

我正在像这样建立我的 public 数组...

var videoId = [String]()

这是从字典的 jsonresponse 中提取出来的代码...

for var i=0; i<items.count; ++i
{
    if let idDict = items[i]["id"] as? NSDictionary
    {
        let id = idDict["videoId"] as! String
        //self.videoId = [id]                    
        self.videoId.append(id)
        print(self.videoId)

这是我的回复......

["Z32Y5MkdICQ"]
["Z32Y5MkdICQ", "UrNb397wS-A"]
["Z32Y5MkdICQ", "UrNb397wS-A", "vzwoJ10UyO0"]
["Z32Y5MkdICQ", "UrNb397wS-A", "vzwoJ10UyO0", "jBmkCoiHC2c"]
["Z32Y5MkdICQ", "UrNb397wS-A", "vzwoJ10UyO0", "jBmkCoiHC2c", "PzpLkcfBe-A"]
["Z32Y5MkdICQ", "UrNb397wS-A", "vzwoJ10UyO0", "jBmkCoiHC2c", "PzpLkcfBe-A", "DmOvILJAYK8"]

["Z32Y5MkdICQ", "UrNb397wS-A", "vzwoJ10UyO0", "jBmkCoiHC2c", "PzpLkcfBe-A", "DmOvILJAYK8", "E5svXAZ9-Qk", "vYH6Sw3A-BA"]
["Z32Y5MkdICQ", "UrNb397wS-A", "vzwoJ10UyO0", "jBmkCoiHC2c", "PzpLkcfBe-A", "DmOvILJAYK8", "E5svXAZ9-Qk", "vYH6Sw3A-BA", "mgZz4L1UmxE"]

当然我只想要最后一个，它是一个 10 videoId 的数组。我怎样才能得到这个？另外，如果你知道..你能在 tableview:cellForRowAtIndexPath 内给我正确的铸造过程吗？

让你的打印不再循环！您不会得到一堆不同的数组，您只是在每次执行循环并附加新项目时打印相同的数组。

for var i=0; i<items.count; ++i
{
    if let idDict = items[i]["id"] as? NSDictionary
    {
        let id = idDict["videoId"] as! String
        //self.videoId = [id]                    
        self.videoId.append(id)
    }
}

print(self.videoId)
