nsurlconnection - Does the iPhone / iPod touch cache data also on disk, or only in memory? -

-

I'm not sure, but I think I was reading some time ago that anything on the iPhone / iPod touch disc Does not cache. Cash only in memory so the cache is not persistent when the app ends. This will bring data back to the net after the relaunching the application. is it true?

You can use the iPhone simulator, open the terminal or finder, and `library / application support / IPhone simulator / user / application / then any directory that you have in your application must be opened.

You will see a document directory, library and tmp directory.

I have never seen whether UIWebView is caching anything but I know that core data

If you exclude your data using CF networks, then I believe that this will allow you to tmp or Keeps the document if you wish.

TMP will not be backed up with the iTunes sync process, but documents , hence will not use documents temporary cache Otherwise you will simply waste the space and slow down the sync backup.

In addition to the removal of the application entirely by the springboard or the total device memory being deleted, the delivery of documents may be anything, including the app upgrade.

In fact, directory directories in the Library directory are caches, webkit / local storage, and preferences so it can suggest some or the other.

The application can not be written to the bundle directory or bad things.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
