Select multiple rows in UITableview [duplicate]

Answer 1

"Selected" rows in Clock application are cells with UITableViewCellAccessoryCheckmark accessory type.

Possible steps to achieve that are:

1. Store checked/not checked state somewhere for each row.
2. In cellForRowAtIndexPath: method for cell in checked row set cell's accessoryType property to UITableViewCellAccessoryCheckmark
3. In cellForRowAtIndexPath: for cell in not checked row set cell's accessoryType property to UITableViewCellAccessoryNone
4. When cell is selected (tapped) deselect it, invert its checked status and reload cell at that index path

Answer 2

In

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

do

    if([tableView cellForRowAtIndexPath:indexPath].accessoryType == UITableViewCellAccessoryCheckmark){
       [tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryNone;
    }else{
       [tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryCheckmark;
    }

Edit:

You also have to use an array that maps the checked cells and in cellForRowAtIndexPath you have to verify if the accessoryType should be checked or not.

Answer 3

Easiest way i've found:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryCheckmark;
}

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
    [tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryNone;
}

You can see which cells are selected by calling:

NSArray *selectedCells = [self.tableView indexPathsForSelectedRows];

Answer 4

If you are using Storyboards, just click on the Table View and then on the Attributes Inspector on the right hand panel, set the "selection" property to "Multiple Selection". I've verified this using Xcode version 8.2.1.
