iphone - CoreData the save method is not working -

-

I am creating an app using coredata for my iPhone

There is a visual controller with the object that I want to save that object to my favorite ViewController. By clicking on the Favorites button I want to save my object in managed objectText, but I am getting the following error:

End the app due to an incomplete exception 'NSInternalInconsistencyException', Reason: 'Trying to do another operation with a fetch already in progress' *

My code: 

  // Step 1: Favorite the object * NewFavorite = (favorite *) [NSEntityDescription insertNewObjectForEntityForName: @Popularity SFTP Dropbox Account object Contaks: managedObjectContext]; // Step 2: Set properties newFavorite.name = @ "Company"; NSLog (@ "% @", newFavorite); // Step 3: Save Item NSError * Error = Zero; If (! [Newfavorite.managedObjectContext save: & amp; error]) {// This is where the program crash NSLog (@ "Unsolved error% @,% @", error, [error user information]); Abortion (); }

I'm not sure what I'm doing wrong

I'm guessing that you have a UI element, such as table, which activates a fetch The UI turns. For example, if you have a controller with no result, then any result of any scrolling in the table can be achieved by the controller's fetch.

You can not change a collection by going through that collection, because the journey is in progress, while the repetition is in the process. An object is repeated on the collection of objects that match its existence and ingenuity. If Fetch is working, then if you include something, then you will get an error.

Normally you see this problem with many threads but I think the UI can set the problem in the right circumstances

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
