ios - Correct adding and UIViewController to another -


आज रात एक का सामना करना पड़ा: 

  - (शून्य) लोड दृश्य {वीसी * वीसी = [[वीसी आलोक] इनिटविथ स्टाइल: यूआईटीबलव्यूस्टाइल समूह []; [आत्म जोड़ें चाइल्डव्यूकंट्रोलर: वीसी]; [Vc removeFromParentViewController]; [स्व सेटव्यू: vc.view]; }   
 और एक बम मिला:  
  अनचाहे अपवाद 'UIViewControllerHierarchyInconsistency', कारण: 'एक दृश्य केवल एक में सबसे अधिक एक दृश्य नियंत्रक के साथ संबद्ध किया जा सकता है पहर!   
 प्रश्न: हम वर्तमान में  vc  और इसकी मौजूदा कार्यक्षमता को वर्तमान  ViewController  बिना  AddSubView  जोड़ सकते हैं?   
 
 
 मौजूदा दृश्य के एक सबव्यू के रूप में अपनी तालिका दृश्य नियंत्रक का दृश्य जोड़ें आपको  removeFromParentViewController  पर  vc  कॉल नहीं करनी चाहिए क्योंकि इससे पहले लाइन को अनिवार्य रूप से नकारना होगा माता-पिता से मेल करने के लिए फ्रेम सेट करना भी एक अच्छा विचार है।  
  - (शून्य) लोड दृश्य {[सुपर लोडव्यू]; // यह एक बुनियादी दृश्य बना देगा VC * vc = [[वीसी आलोक] initWithStyle: UITableViewStyleGrouped]; [आत्म जोड़ें चाइल्डव्यूकंट्रोलर: वीसी]; Vc.view.frame = self.view.bounds; Vc.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; [self.view addSubview: vc.view]; [Vc didMoveToParentViewController: self]; }

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c# - passing input text from view to contoller with FacebookContext using Facebook app -

Calling a C++ function from C# by passing a string with variable size to it -

I am calling a string with a C + code and calling from the C # code. The C ++ function is responsible for filling the string material. The following code is: C #party: var abc = new string builder (4096); // will have to change this var result = Basic methods. SignCrcFile (ABC); C ++: bool __cdecl SignCrcFile (char * abc) {... char * tempStr = "hello all"; // for example // copy it to ABC string strcpy (ABC, tempStr); Back true; } The problem is that tempStr's size in the C ++ function is dynamic (the above assignment for TempStr is only an example). In such a case, it is not a hard code that the size of ABC string is in the size of 4096 bytes on the C #. The first solution can be a solution to create 2 functions on the C ++ side to get the size of the string. Then allocate that size using StringBuilder in the C # side then use the next function to bring the entire string from C ++ to the C #. But no suggestion this may not be the most optimal way? ...
