How can I tell if a UITableView contains a specific NSIndexPath?

Question

Here is the code I\'m using:

if (appDelegate.currentMainIndexPath != nil /* && doesPathExistInTableView */)
{
    [tblView scrollToRowAtIndexPath:appDele         


        

Answer 1

There is a more convenient method to tell if a indexPath is valid:

For Swift 3.0:

open func rectForRow(at indexPath: IndexPath) -> CGRect

For Objective-C

- (CGRect)rectForRowAtIndexPath:(NSIndexPath *)indexPath;

You will get CGRectZero if the indexPath is invalid.

func isIndexPathValid(indexPath: IndexPath) -> Bool {
    return !tableView.rectForRow(at: indexPath).equalTo(CGRect.zero)
}
