Sort a tableview

[iAppCode]

Hi,
I would like to sort my entries in my tableview after the detailtextlabel.
Do you know how to do that???

Thanks,

The answer depends. How are you providing data for your table view? Are you using Core Data, an array of items, or some other form of model?

Core Data provides support for sorting items in a table view.

If you're using an array as your data model, you can simply sort your array in place (if its a mutable array) or replace the array with a sorted version, and then call reloadData on the table view to get it to reload all it's cells.

Ok great! I am using a MutableArray. How can I sort it alphabetically?
Thank you!

well I found a solution myself:

[yourArray sortUsingSelector:@selector(localizedCaseInsensitiveCompare:)];

But the problem is that I have got all my songs from the Music Library as NSStrings in the TableView. In contrast to Apple I want to sort these songs after the artists which are in the detailtextlabel. How to do this I have to find out now.

You can do multi-key sorts using sort NSSortDescriptor objects. You create an array of sort NSSortDescriptors, and then use the method sortUsingDescriptors: to sort the array.

Don't think of it in terms of sorting by cell label and detail label. The table view is a way of displaying the underlying data. You sort the data, and the table view updates to show the new order.

How are you organizing the data that you display in the table view? Do you have a single array of records, each of which holds the artist and song name for each song?
