What does the iOS error “request for rect of invalid section” mean?

Question

Google reveals no posts at all for this error message. I\'m getting it in iOS 5 trying to update a UITableView. While the exact code is a bit tortured, this is what I\'m doi

Answer 1

Leaving this here as well as a separate possible cause.

If you are trying to delete rows in the moveRowAtIndexPath: method you will get the same crash. You have to wait until it finishes to do that.

Answer 2

Looks like your code is trying to work with a section of your table that does not exist.

Since NSArrays are zero-indexed, the index value of count will be outside the bounds of the array. You should subtract one from the count when using indexSetWithIndex: here:

[table insertSections: [NSIndexSet indexSetWithIndex: [sections count]-1] 
                                    withRowAnimation: UITableViewRowAnimationNone];

Answer 3

Posting as answer in case it happens to somebody else as well.

I found the issue looking at jonkroll's answer, but in my case this happened because I was calling the same method twice and that method removed a row from the table view.
