我试图做一些非常简单的事情;获得与我在您的应用中显示的视频结果相同的搜索结果，当您搜索Youtube.com并按Upload count排序时。Youtube API v3 search.list返回不相关的视频Swift
几乎一切工作正常，我可以：
- 获取缩略图，标题和频道名称
- 播放视频
*上获取每个视频的观看次数太多工作（我听说你需要 来创建两个请求？）
真正让我困惑的是这个代码：
var urlString = "https://www.googleapis.com/youtube/v3/search?
part=snippet
&fields=items(id,snippet(title,channelTitle,thumbnails))
&order=viewCount
&q=\(searchBar.text)
&type=video
&maxResults=25&key=\(apiKey)"
会产生这样的结果：
，而不是这样的：
*不包括播放列表
什么是错我的代码？
func searchBarSearchButtonClicked(searchBar: UISearchBar) {
searchBar.resignFirstResponder()
// Form the request URL string.
var urlString = "https://www.googleapis.com/youtube/v3/search?part=snippet&fields=items(id,snippet(title,channelTitle,thumbnails))&order=viewCount&q=\(searchBar.text)&type=video&maxResults=25&key=\(apiKey)"
urlString = urlString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())!
// Create a NSURL object based on the above string.
let targetURL = NSURL(string: urlString)
// Get the results.
performGetRequest(targetURL, completion: { (data, HTTPStatusCode, error) -> Void in
if HTTPStatusCode == 200 && error == nil {
// Convert the JSON data to a dictionary object.
let resultsDict = (try! NSJSONSerialization.JSONObjectWithData(data!, options: [])) as! Dictionary<NSObject, AnyObject>
// Get all search result items ("items" array).
let items: Array<Dictionary<NSObject, AnyObject>> = resultsDict["items"] as! Array<Dictionary<NSObject, AnyObject>>
// Loop through all search results and keep just the necessary data.
for var i=0; i<items.count; ++i {
let snippetDict = items[i]["snippet"] as! Dictionary<NSObject, AnyObject>
// let statisticsDict = items[i]["statistics"] as! Dictionary<NSObject, AnyObject>
// Create a new dictionary to store the video details.
var videoDetailsDict = Dictionary<NSObject, AnyObject>()
videoDetailsDict["title"] = snippetDict["title"]
videoDetailsDict["channelTitle"] = snippetDict["channelTitle"]
videoDetailsDict["thumbnail"] = ((snippetDict["thumbnails"] as! Dictionary<NSObject, AnyObject>)["default"] as! Dictionary<NSObject, AnyObject>)["url"]
videoDetailsDict["videoID"] = (items[i]["id"] as! Dictionary<NSObject, AnyObject>)["videoId"]
// videoDetailsDict["viewCount"] = statisticsDict["viewCount"]
self.videosArray.append(videoDetailsDict)
// Reload the tableview.
self.tableView.reloadData()
}
}
else {
print("HTTP Status Code = \(HTTPStatusCode)")
print("Error while loading channel videos: \(error)")
}
})
}
// MARK: Custom method implementation
func performGetRequest(targetURL: NSURL!, completion: (data: NSData?, HTTPStatusCode: Int, error: NSError?) -> Void) {
let request = NSMutableURLRequest(URL: targetURL)
request.HTTPMethod = "GET"
