Radio button behaviour in table view

[mini998]

I have a table view that contains many rows from a sqlite table ,I need to restrict the number of cells user can select and continue to the next view . Kind of like the radio button feature . The number of rows need to be restricted can vary from 1 to 10 depending on the situation.

I found this tutorial Osmorphis: Radio-button behavior for table rows

but it was written good 3 years back ,is there an obvious way to do this in xcode 4?

cheers

First off, please don't discredit code written years ago. It still works, the only code that should be reworked are big blobs of code that are basically hacks to get features that weren't available in the SDK but are now. To accomplish your idea, you'll need to create an array called indexPathsOfSelectedRows. When a user touches a row, check whether the amount of objects in the array is greater than your maximum. If so, delete the object at index 0. Then, add the indexpath of the row that user just touched. Then reload your tableview.

In the cellForRowAtIndexPath, you'll want to check whether your array contains the indexPath. If so, give it a checkmark, if not, don't.

indexPathsForSelectedRows is only available in IOS5 isn't it ? then its no use .

I am talking about creating an instance variable.
