How to deselect a selected UITableView cell?

Question

I am working on a project on which I have to preselect a particular cell.

I can preselect a cell using -willDisplayCell, but I can't deselect it when the user clicks on any other cell.

- (void)tableView:(UITableView*)tableView 
        willDisplayCell:(UITableViewCell*)cell
        forRowAtIndexPath:(NSIndexPath*)indexPath
{ 
    AppDelegate_iPad *appDelegte = 
      (AppDelegate_iPad *)[[UIApplication sharedApplication] delegate];

    if ([appDelegte.indexPathDelegate row] == [indexPath row])
    {
        [cell setSelected:YES];    
    } 
}

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

    AppDelegate_iPad *appDelegte = 
      (AppDelegate_iPad *)[[UIApplication sharedApplication] delegate];

    NSIndexPath *indexpath1 = appDelegte.indexPathDelegate;
    appDelegte.indexPathDelegate = indexPath;
    [materialTable deselectRowAtIndexPath:indexpath1 animated:NO];
}

Can you help?

Answer 1

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 2

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

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

Answer 3

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)
}

Answer 4

Try this:

for (NSIndexPath *indexPath in tableView.indexPathsForSelectedRows) {
    [tableView deselectRowAtIndexPath:indexPath animated:NO];
}

Answer 5

Please check with the delegate method whether it is correct or not. For example;

-(void) tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath

for

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

Answer 6

Swift 4:

tableView.deselectRow(at: indexPath, animated: true)

Answer 7

This is a solution for Swift 4

 in tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)

just add

tableView.deselectRow(at: indexPath, animated: true)

it works like a charm

example:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        tableView.deselectRow(at: indexPath, animated: true)
//some code
}

In addition to setting the cell as selected, you also need to inform the tableView that the cell is selected. Add a call to -tableView:selectRowAtIndexPath:animated:scrollPosition: to your willDisplayCell: method: and you will be able to deselect it as normal.

- (void)tableView:(UITableView*)tableView 
  willDisplayCell:(UITableViewCell*)cell
forRowAtIndexPath:(NSIndexPath*)indexPath
{ 
    AppDelegate_iPad *appDelegte = (AppDelegate_iPad *)[[UIApplication sharedApplication] delegate];

    if ([appDelegte.indexPathDelegate row] == [indexPath row])
    {
        // SELECT CELL
        [cell setSelected:YES]; 
        // TELL TABLEVIEW THAT ROW IS SELECTED
        [tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];   
    } 
}

Be sure to use UITableViewScrollPositionNone to avoid odd scrolling behavior.

Answer 9

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 10

This should work:

[tableView deselectRowAtIndexPath:indexpath1 animated:NO];

Just make sure materialTable and tableView are pointing to the same object.

Is materials connected to the tableView in Interface Builder?

Answer 11

If you want to select any table cell with the first click and deselect with the second, you should use this code:

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

    if (self.selectedIndexPath && 
        [indexPath compare:self.selectedIndexPath] == NSOrderedSame) {

        [tableView deselectRowAtIndexPath:indexPath animated:YES];
         self.selectedIndexPath = nil;
    } 
    else {
        self.selectedIndexPath = indexPath;
    }
}

Answer 12

Swift 4:

func tableView(_ tableView: UITableView, willSelectRowAt indexPath: IndexPath) -> IndexPath? {
    let cell = tableView.cellForRow(at: indexPath)
    if cell?.isSelected == true { // check if cell has been previously selected
        tableView.deselectRow(at: indexPath, animated: true)
        return nil
    } else {
        return indexPath
    }
}

Answer 13

Swift 2.0:

tableView.deselectRowAtIndexPath(indexPath, animated: true)

Answer 14

Swift 3/4

In ViewController:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    tableView.deselectRow(at: indexPath, animated: true)
}

In Custom Cell:

override func awakeFromNib() {
    super.awakeFromNib()
    selectionStyle = .none
}

Answer 15

try this

[self.tableView deselectRowAtIndexPath:[self.tableView indexPathForSelectedRow] animated:YES];

Answer 16

NSIndexPath * index = [self.menuTableView indexPathForSelectedRow];
[self.menuTableView deselectRowAtIndexPath:index animated:NO];

place this code according to your code and you will get your cell deselected.

Answer 17

Swift 3.0:

Following the protocol conformance section of the ray wenderlich swift style guide, to keep related methods grouped together, put this extension below your view controller class like that:

// your view controller
class MyViewcontroller: UIViewController {
  // class stuff here
}

// MARK: - UITableViewDelegate
extension MyViewcontroller: UITableViewDelegate {
      // use the UITableViewDelegate method tableView(_:didSelectRowAt:)
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        // your code when user select row at indexPath

        // at the end use deselectRow
        tableView.deselectRow(at: indexPath, animated: true)
    }
}

Answer 18

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 19

Swift

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    // your code

    // your code

    // and use deselect row to end line of this function

    self.tableView.deselectRowAtIndexPath(indexPath, animated: true)

}

Answer 20

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    tableView.deselectRow(at: indexPath, animated: true)
}

Answer 21

Swift 3

I've run into this as well - when you navigate or unwind back to the table view it usually doesn't deselect the previously selected row for you. I put this code in the table view controller & it works well:

override func viewDidAppear(_ animated: Bool) {
    if let lastSelectedRow = tableView.indexPathForSelectedRow {
        tableView.deselectRow(at: lastSelectedRow, animated: true)
    }
}
