NSURLErrorDomain Error Code -1005
提问by NumberOneRobot
I'm working on the CS193p coursework from Stanford (I'm not a Stanford student I'm just trying to learn), assignment number 5, where we have to get images from Flickr using calls to the Flickr api. I'm only trying to download a list of the pictures and print them out to the console, but I'm getting an NSURLErrorDomain with code -1005. The error message I am printing out is below:
我正在研究斯坦福大学的 CS193p 课程（我不是斯坦福大学的学生，我只是想学习），作业编号 5，我们必须使用对 Flickr api 的调用从 Flickr 获取图像。我只是想下载图片列表并将它们打印到控制台，但我收到了代码为 -1005 的 NSURLErrorDomain。我打印出来的错误信息如下：
error: Error Domain=NSURLErrorDomain Code=-1005 "The operation couldn't be completed. (NSURLErrorDomain error -1005.)"

错误：错误域=NSURLErrorDomain 代码=-1005“操作无法完成。（NSURLErrorDomain 错误-1005。）” UserInfo=0x7f9449c83df0 {NSErrorFailingURLStringKey= https://api.flickr.com/services/rest/?method= flickr.places.getTopPlacesList＆place_type_id = 7＆格式= JSON＆nojsoncallback = 1＆API_KEY = 4f9c3155b34836b2ac15318d98b93f3a，NSErrorFailingURLKey = https://api.flickr.com/services/rest/?method=flickr.places.getTopPlacesList&place_type_id=7&format=json&nojsoncallback=1&api_key=4f9c3155b34836b2ac15318d98b93f3a，_kCFStreamErrorDomainKey = 1 , _kCFStreamErrorCodeKey=57, NSUnderlyingError=0x7f9449c7fca0“操作无法完成。（kCFErrorDomainCFNetwork错误-1005。）”}
The Flickr API call is happening in the following method:
Flickr API 调用发生在以下方法中：
NSURLSession *urlSession = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration ephemeralSessionConfiguration]];
NSURLSessionDownloadTask *downloadTask = [urlSession downloadTaskWithURL:[FlickrFetcherHelper URLforTopPlaces] completionHandler:^(NSURL *location, NSURLResponse *response, NSError *error) {
NSArray *topPlaces;
if (!error) {
topPlaces = [[NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfURL:location] options:0 error:&error] valueForKeyPath:FLICKR_RESULTS_PLACES];
}
dispatch_async(dispatch_get_main_queue(), ^{
completionHandler(topPlaces, error);
});
}];
[downloadTask resume];
I'm using xCode 6, not sure if that has anything to do with the problem. The same code was working a couple days ago, and I don't think I changed anything that would mess it up, but it clearly has.
我正在使用 xCode 6，不确定这是否与问题有关。相同的代码几天前还在工作，我认为我没有改变任何会搞砸的东西，但它显然有。

Are you using the iOS8 (iPhone 6 for example) simulator? If so, try changing to iPhone 5s. I was having the same problem and switched my simulator and all worked well again. I tried this after reading the following feedback: https://github.com/AFNetworking/AFNetworking/issues/2314
您使用的是 iOS8（例如 iPhone 6）模拟器吗？如果是这样，请尝试更换为 iPhone 5s。我遇到了同样的问题并切换了我的模拟器，并且一切正常。我在阅读以下反馈后尝试了这个：https: //github.com/AFNetworking/AFNetworking/issues/2314

Switch to iOS Simulator and do "Reset Content and Settings ..." from top menu.
切换到 iOS 模拟器并从顶部菜单执行“重置内容和设置...”。
