Is it possible to prevent iOS 11 to log -999(NSURLErrorCancelled) error when NSURLSessionDataTask was cancelled?
iOS11, Xcode 9.
CODE:
- (void)testURLSession{
NSURLSession *urlSession = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLSessionDataTask *dataTask;
NSString *requestUrl = @"https://www.apple.com/";
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:requestUrl]];
for (NSInteger i = 0; i < 3 ; i++) {
if (dataTask) {
[dataTask cancel];
dataTask = nil;
}
dataTask = [urlSession dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error){
if ([error code] == NSURLErrorCancelled) {
NSLog(@"Cancelled");
}
}];
[dataTask resume];
}
}
OUTPUT:
Cancelled
Cancelled

Task <6B4808BC-3911-44D7-B1D6-C5BDFC2881B3>.<2> finished with error - code: -999
