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]; }

ios - Does Core Data autoupdate a many to many relationship on saving -

I have used 2 database tables and core data / NSManagedObjects in SQLite: User is user_id name group (multiple groups) Group group_id title group members (multiple users) By using core data to save a group and adding users ( Add to group) as follows: group * cordata = zero; Cordata = [NSEntityDescription insertNewObjectForEntityForName: @ Managed Object Contains in "Groups": Reference]; Request = [NSFetchRequest fetchRequestWithEntityName: @ "user"]; Request.predicate = [NSPredicate predicateWithFormat: @ "user_id =% @", user_id]; Result = [reference executeFetchRequest: request error: & amp; Error]; CoreData.group_id = group_id Cordettitle = Title [Cordata AdGroupMailersObject: [Last objections result]]; Is it right to say that core data manages a user with multiple users and groups with the code above? Yes, if the relationships are in the form of each other's inverse relationship The inverse relationships are updated automaticall...

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? ...
