  • Strange problem with NSMutableArray - Possibly some memory corruption

    - by user210504
    Hi! I am trying to update data in a table view using a NSMutableArray. Quite simple :( What is happening is that I get my data from a NSURLConnection Callback, which I parse and store it in an array and call reload data on the table view. The problem is that when cellForRowAtIndexPath is called back by the framework. The array still shows the correct count of the elements but all string objects I had stored earlier are shown as invalid. Any pointers

  • reflection paths between points in2d

    - by Chris H
    Just wondering if there was a nice (already implemented/documented) algorithm to do the following Given any shape (without crossing edges) and two points inside that shape, compute all the paths between the two points such that all reflections are perfect reflections. The path lengths should be limited to a certain length otherwise there are infinite solutions. I'm not interested in just shooting out rays to try to guess how close I can get, I'm interested in algorithms that can do it perfectly. Search based, not guess/improvement based.

    - by ncohen
    Hi everyone, I was wondering if I need to release a copied NSObject? For example, I create only one dictionary that I copy into an array: Code: for (int num = 0; num < [object count]; num++) { [dictionary setObject:[object objectAtIndex:num] forKey:@"x"]; [array addObject:[dictionary copy]]; } Do I have to release the dictionary? If yes, when? Thanks

  • Objective-C: Loop through NSDictionary to create seperate NSArray's

    - by Nic Hubbard
    I have a large NSDictionary structure that I need to loop through and create seperate NSArray's. Here is the structure: ( { id = { text = ""; }; sub = { text = " , "; }; text = ""; "thumb_url" = { text = ""; }; title = { text = "2010-2011"; }; type = { text = "title"; }; }, { id = { text = "76773"; }; sub = { text = "December 13, 2010"; }; text = ""; "thumb_url" = { text = "http://www.puc.edu/__data/assets/image/0004/76774/varieties/thumb.jpg"; }; title = { text = "College Days - Fall 2010"; }; type = { text = "gallery"; }; }, { id = { text = ""; }; sub = { text = ""; }; text = ""; "thumb_url" = { text = ""; }; title = { text = "2009-2010"; }; type = { text = "title"; }; }, { id = { text = "76302"; }; sub = { text = "December 3, 2010"; }; text = ""; "thumb_url" = { text = "http://www.puc.edu/__data/assets/image/0019/76303/varieties/thumb.jpg"; }; title = { text = "Christmas Colloquy"; }; type = { text = "gallery"; }; } ) Each section has a type key, which I need to check. When it finds the "title" key, I need to add those to an array. Then the next sections that would use the "gallery" key needs to be in its own array until it finds another "title" key. Then the "gallery" keys after that into their own array. I am using this a UITableView section titles and content. So, the NSDictionary above should have one NSArray *titles; array, and two other arrays each containing the galleries that came after the title. I have tried using a for loop but I just can't seem to get it right. And ideas would be appreciated.

  • Call a constructor from variable arguments with PHP

    - by zneak
    Hello guys, I have a function that takes variadic arguments, that I obtain from func_get_args(). This function needs to call a constructor with those arguments. However, I don't know how to do it. With call_user_func, you can call functions with an array of arguments, but how would you call a constructor from it? I can't just pass the array of arguments to it; it must believe I've called it "normally". Thank you!

  • Threading cost - minimum execution time when threads would add speed

    - by Lukas
    I am working on a C# application that works with an array. It walks through it (meaning that at one time only a narrow part of the array is used). I am considering adding threads in it to make it perform faster (it runs on a dualcore computer). The problem is that I do not know if it would actually help, because threads cost something and this cost could easily be more than the parallel gain... So how do I determine if threading would help?

  • What is the meaning of the following?

    - by vj
    int sampleArray[] = {1,2,3,4,5}; I understand that the sampleArray now points to the first element of the array. However, what does it mean when I say &sampleArray ? Does it mean I am getting the address of the sampleArray variable? Or does it mean a two dimensional array variable? So, i can do this: int (*p)[5] = &sampleArray? Thanks
