Answer 1

Can you try this?

- (void)tableView:(UITableView *)tableView 
  didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    AppDelegate_iPad *appDelegte = 
    (AppDelegate_iPad *)[[UIApplication sharedApplication] delegate];
    NSIndexPath *indexpath1 = appDelegte.indexPathDelegate;
    appDelegte.indexPathDelegate = indexPath;

    UITableViewCell *prevSelectedCell = [tableView cellForRowAtIndexPath: indexpath1];
    if([prevSelectedCell isSelected]){
       [prevSelectedCell setSelected:NO];
    }
}

It worked for me.

Answer 2

Based on saikirans solution, I have written this, which helped me. On the .m file:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    if(selectedRowIndex && indexPath.row == selectedRowIndex.row) {

        [tableView deselectRowAtIndexPath:indexPath animated:YES];
        selectedRowIndex = nil;

    }

    else {  self.selectedRowIndex = [indexPath retain];   }

    [tableView beginUpdates];
    [tableView endUpdates];

}

And on the header file:

@property (retain, nonatomic) NSIndexPath* selectedRowIndex;

I am not very experienced either, so double check for memory leaks etc.

Answer 3

use this code

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
 {
    //Change the selected background view of the cell.
     [tableView deselectRowAtIndexPath:indexPath animated:YES];
 }

Swift 3.0:

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    //Change the selected background view of the cell.
    tableView.deselectRow(at: indexPath, animated: true)
}

Answer 4

Use the following method in the table view delegate's didSelectRowAtIndexpath (Or from anywhere)

[myTable deselectRowAtIndexPath:[myTable indexPathForSelectedRow] animated:YES];

Answer 5

To have deselect (DidDeselectRowAt) fire when clicked the first time because of preloaded data; you need inform the tableView that the row is already selected to begin with, so that an initial click then deselects the row:

//Swift 3:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    if tableView[indexPath.row] == "data value"

        tableView.selectRow(at: indexPath, animated: false, scrollPosition: UITableViewScrollPosition.none)

    }
}

Answer 6

It might be useful to make an extension in Swift for this.

Swift 4 and Swift 5:

Swift extension (e.g. in a UITableViewExtension.swift file):

import UIKit

extension UITableView {

    func deselectSelectedRow(animated: Bool)
    {
        if let indexPathForSelectedRow = self.indexPathForSelectedRow {
            self.deselectRow(at: indexPathForSelectedRow, animated: animated)
        }
    }

}

Use e.g.:

override func viewWillAppear(_ animated: Bool)
{
    super.viewWillAppear(animated)

    self.tableView.deselectSelectedRow(animated: true)
}
