Question

我确信这是一个完全愚蠢的问题。我有一个viewController，它位于TabBarController内的导航控制器内。 Apple表示这是实现该设置的正确方法。但是，我如何为该复合体准备ForSeque并将数据发送到第一个ViewController。

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "presentActionItems" {
        println("preparing")
        let tabBarController:actionItemsTabController = segue.destinationViewController as! actionItemsTabController

        let navigationController = ???
        let viewController = ???

        viewController.givenURL = actionItemsURL
    }
}

我相信这是一个简单的问题，我可以帮忙吗？

在传递数据后，在TabController的viewDidLoad中尝试此操作

#include <fstream>
#include <iostream>
#include <string>
#include <vector>
using namespace std;


int main (){



std::vector< int > interrogation ;
std::vector< int > dot;



string look = "?";
string look_again = ".";


string test = "ver. o que e isto? nao sei. ola? adeus. fghfghfhfghf";



string::size_type pos = test.find(look);
string::size_type sop = test.find(look_again);
string::size_type exc = test.find(look_again_again);


while (pos != std::string::npos)
{



int a = pos ;
int b = sop;



   cout << " . found at : " << sop << std::endl;
   cout << " ? found at : " << pos << std::endl;

interrogation.push_back(a);
dot.push_back(b);


string fragment = test.substr (0 , pos );    // works
//cout << fragment << endl ;

string fragment2 = test.substr (0 , sop );    // works
//cout << fragment2 << endl ;


  pos = test.find(look, pos + 1);
  sop = test.find(look_again, sop + 1);

}





int x = 1;

if(x > 0){





int a = 1;

int q = dot[a];
int w = interrogation[a];
// to save text


// to save text
string save = "saved_question.txt" ;
ofstream myfile;
myfile.open (save.c_str(), ios::app);
myfile << test.substr( 18, 20 ) + "\n"  ;
myfile.close();


cout << "Question saved in text file" << endl;




}



}
