Question

Targeting iOS 5.0 I see SIGABRT when I try to access row or section properties of NSIndexPath object in the following code:

NSIndexPath* path = [[NSIndexPath alloc] initWithIndex:0];
int row = path.row; //SIGABRT
int section = path.section;//SIGABRT

This example suggests using indexPathWithIndex: instead http://developer.apple.com/library/mac/#samplecode/SourceView/Listings/BaseNode_m.html#//apple_ref/doc/uid/DTS10004441-BaseNode_m-DontLinkElementID_6

path = [NSIndexPath indexPathWithIndex:0];

The results remain consistent. Does anyone have an explanation of why this might happen? Is it that we just cannot operate on NSIndexPath in iOS 5.0?

Thanks in advanced.

Answer 1

Try creating the index path using indexPathForRow:inSection:

NSIndexPath* path = [NSIndexPath indexPathForRow:0 inSection:0];
