iphone - Calculate the size of a folder -


Just a quick one ...

I was making a folder for cache images inside the document My iPhone app I want to be able to keep this folder size up to 1 MB, so I need to check the size in the bytes of my folder.

I have the code to calculate the size of the file, but I need the size of the folder.

What would be the best way to do this? Will I need a loop through each file?

Cheers

Cheers for that Alex, you've helped a lot, Now the following is the task which is written the trick ... 

  - (unsigned long long int) folder size: (NSString *) folder path {NSArray * filesArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath: Folder Path Error: zero]; NSEnumerator * filesEnumerator = [FilesArray objectEnumerator]; NSString * fileName; Unsigned long file file size = 0; While {fileName = [FilesEnumerator nextObject]) {NSDictionary * fileDictionary = [[NSFileManager defaultManager] File attributeAppet: [FolderPath stringBeffingPath Company: Filename] Trust link: Yes]; FileSize + = [fileDictionary file size]; } Return file size; }

The explorer does as it comes with the exact number of bytes.

On one side, Finder returns the number two. The size on one disk is the actual number of the second bytes.

For example, when I run this code from my folders, it comes back in code with 'File Size' of 130398. When I check in Finder, then it says that size is 201KB on disk (130,398 bytes).

Whether to go with the actual size here (201 KB or 130,398 bytes) is a little uncertain, for now, I will go to the safe side and cut my threshold to half as long as I I do not know what it means ...

If someone can add more information to these different numbers, then I appreciate it.

Cheers,

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
