How to deselect a selected UITableView cell?

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?

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)
}

There is a didDeselectRowAtIndexPath to use to deselect the previous one.
I like to think I can't upvote this post because it would cause an integer overflow :)
hi @ram, you need to select an answer on this question
I don't understand... this code is never going to let anything get selected.
@matrixugly is right. It's more appropriate to do this inside willSelectRowAt:. See a more complete answer here: stackoverflow.com/questions/12693402/…

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

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

It's worth noting that indexPathForSelectedRow is a method and not a property.
Sweet! Didn't know about [myTable indexPathForSelectedRow]. I was looping through the cells before. Thanks!
@FreeAsInBeer Is this distinction important somehow? Property accessors are methods.
@chaiguy That's fine if you don't mind your colleagues considering you evil.
@Supertecnoboff There is no difference in performance between the two variations.

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)
}

In my opinion, this answer is better because putting the desolation in the viewWillAppear() method helps the user to understand where he comes back from.
the perfect one as i needed

Try this:

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

Good job... I think 'index' on the 2nd line should be indexPath
this is not supported on iOS 11 Swift 4

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

Was calling the wrong method this whole time, arghh!! Thank you!
oh man.... bloody autocompletion!!! It took me several hours to figure it out!!! OMG...I want to kiss you!

Swift 4:

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

Doesn't need to be declared non-optional but this is correct.

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
}

until you add selection on editing in your tableview, it will be impossible to select any cell because it will deselect it when you done selecting it :)
This is certainly the correct approach, when you're not editing, when you're "tapping a row to do something"

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.


Absolutely correct. I think that [cell setSelected:YES] could be omitted: selectRowAtIndexPath will take care of the cell's selected state
This answer works for UITableView's with multiple selections. Thumbs up.

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.

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?


i have tested with NO but that also not solve my problem. but i fixed this issue with another way as reloaded Data when ever the didselect delegate fired.

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;
    }
}

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
    }
}

This worked for me in Swift 3. Just had to add self.tableView(tableView, didDeselectRowAt: indexPath) after tableView.deselectRow... because it was not called automatically

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
}

try this

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

try explaining your answer, else it should be a comment.

rahulchona
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.

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.

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)

}

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)
    }
}

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)
    }
}

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)

    }
}
