IMDB 中的 lldb 错误 API
lldb Error in IMDB API
我想在我的 Xcode 输出中打印 IMDB JSON 请求。
无论用户向搜索栏写入什么内容，我都希望从 IMDB 获得 JSON 对 低俗小说 的请求，然后在 Xcode 输出中打印。
我的要求：http://www.omdbapi.com/?t=pulp+fiction
但它给出了 lldb 错误
Xcode 输出：

在搜索栏点击回车后。 （我写了一些东西然后点击了，我写的东西并不重要，因为我只想得到 低俗小说 现在用户写到搜索栏的任何内容。）
(lldb)
然后就出现了这个画面。

每次你 "force" 使用 Swift 中的东西 ! 你 运行 有崩溃的风险。而且，当您同时发生许多事情时，要找出哪里出了问题会变得很棘手。
这样试试：
func searchForMovie(title: String) {
//http://www.omdbapi.com/?t=pulp+fiction
if let movie = title.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed) {
if let url = URL(string: "https://www.omdbapi.com/?t=pulp+fiction") {
let session = URLSession.shared
let task = session.dataTask(with: url, completionHandler: { (data, response, error) in
if error != nil {
print(error!)
} else {
if let d = data {
do {
let jsonResult = try JSONSerialization.jsonObject(with: d, options: JSONSerialization.ReadingOptions.mutableContainers)
print(jsonResult)
} catch {
}
}
