所以最后，我有一个代码，它有效！
NSString *content = @"field1=42&field2=Hello";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.example.com/form.php"]];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:[content dataUsingEncoding:NSUTF8StringEncoding]];
// generates an autoreleased NSURLConnection
[NSURLConnection connectionWithRequest:request delegate:self];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:JSONURL];
NSURLSessionDataTask * dataTask = [[NSURLSession sharedSession] dataTaskWithRequest:request
completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if(data == nil){
completion(nil,error);
return;
}
NSError *myError;
NSArray *tableArray = [[NSArray alloc]initWithArray:[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&myError]];
completion(tableArray,myError);
}];
[dataTask resume];
}
