NSString *dataUrl = @"https://st2.depositphotos.com/2001755/5408/i/450/depositphotos_54081723-stock-photo-beautiful-nature-landscape.jpg";
NSURL *url = [NSURL URLWithString:dataUrl];
NSURLSessionConfiguration *configuration = NSURLSessionConfiguration.defaultSessionConfiguration;
configuration.allowsCellularAccess = YES;
configuration.waitsForConnectivity = YES;
configuration.allowsExpensiveNetworkAccess = YES;
configuration.allowsConstrainedNetworkAccess = YES;
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration];
NSURLSessionDataTask *downloadTask = [session
dataTaskWithURL:url completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSLog(@"%@", error);
}];
[downloadTask resume];
我们有一个 2015 年开发的旧应用程序，它有很多旧代码。在 iOS 13 上，不幸的是在 CELLULAR 上所有 NSURLSession 请求(不仅对我们的服务器而且对任何服务器)都失败并出现错误:
Error Domain=NSURLErrorDomain Code=-1009 "The Internet connection appears to be offline." UserInfo={_kCFStreamErrorCodeKey=50, NSUnderlyingError=0x280526af0 {Error Domain=kCFErrorDomainCFNetwork Code=-1009 "(null)" UserInfo={NSURLErrorNetworkUnavailableReasonKey=1, kCFStreamErrorCodeKey=50, kCFStreamErrorDomainKey=1}}, NSURLErrorNetworkUnavailableReasonKey=1, NSLocalizedDescription=The Internet connection appears to be offline.
其中 NSURLErrorNetworkUnavailableReasonKey=1 是 URLError.NetworkUnavailableReason.expensive
NSURLConnection 请求没问题(弃用警告除外)
我应该打开什么全局设置，或者至少是本地设置，才能发出成功的请求？
最佳答案
经过 7 小时的调查，我发现问题出在库 CCInfiniteScrolling (github.com/ziryanov/CCInfiniteScrolling)。 NSObject 类别的问题和错误的运行时编码:NSObject+DProperty.m。我们将所有内容重写为 object_associations 并且一切正常。
关于ios - nsurlsession ios 13 蜂窝错误域=NSURLErrorDomain 代码=-1009 "The Internet connection appears to be offline."，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58052982/
