i am confused about indexPath and indexPath.row, does each cell of a tableView correspond to an indexPath? so why do we look for the "row" of this indexPath? i checked the doc but i think it confuses me.
i found this code :
// this method is used in case the user scrolled into a set of cells that don't have their app icons yet
- (void)loadImagesForOnscreenRows
{
if ([self.entries count] > 0)
{
NSArray *visiblePaths = [self.tableView indexPathsForVisibleRows];
for (NSIndexPath *indexPath in visiblePaths)
{
AppRecord *appRecord = [self.entries objectAtIndex:indexPath.row];
if (!appRecord.appIcon) // avoid the app icon download if the app already has an icon
{
[self startIconDownload:appRecord forIndexPath:indexPath];
}
}
}
}
Can you explain me the difference between the two?
Thanks a lot
Paul
Each instances of NSIndexPath class has two properties: row and section (Documentation)
Each cell of tableView corresponds to unique indexPath (N-th row in M-th section). Often there is only one section and people use only row
to reference to the data.
