Does UITableView have an array property that holds all of the cells? - ios

Question

In one of my methods I want to iterate between the cells I have and perform changes on them, something like:
for (UITableViewCell *cell in ___________) {
cell.accessoryType = accessoryType = UITableViewCellAccessoryCheckmark;
}
so is there a property that will complete the ____________ ?
tnx!

Answer 1

There are only visible cells array self.tableView.visibleCells
for (UITableViewCell *cell in self.tableView.visibleCells) {
cell.accessoryType = accessoryType = UITableViewCellAccessoryCheckmark;
}

Answer 2

The UITableView itself doesn't know much about its content. That's the job of it's dataSource delegate. See documentation for UITableViewDataSource
Rather than thinking of the problem in a linear fashion. Think of the problem as event driven. If you want to modify the cell before it is displayed, you can check out tableView:willDisplayCell:forRowAtIndexPath: on the UITableViewDelegate
edit: given that you are looking to set the accesoryType you should probably try using tableView:cellForRowAtIndexPath:. Since that's where you're either dequeueing a reusable cell or manually alloc] init]'ing one .

Answer 3

Have you tried: yourTableView.visibleCells

Answer 4

Chikabuz is right.
BUT you should avoid making changes to the cells like this. Instead you should tell the tableView that your cells are updated and provide the changes in - [id<UITableViewDataSource> tableView:cellForRowAtIndexPath:] like so:
- (IBAction)toggleSelecting:(id)sender {
[[self tableView] setEditing:![[self tableView] isEditing] animated:YES];
// or with custom use with own BOOL property:
// [self setEditing:![self editing]];
[[self tableView] reloadRowsAtIndexPaths:[[self tableView] indexPathsForVisibleRows] withRowAnimation:UITableViewRowAnimationFade];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
// cell setup here...
// or with custom use with own BOOL property:
// if ([self editing]) {
if ([[tableView] isEditing]) {
[cell setAccessoryType:UITableViewCellAccessoryCheckmark];
}
return cell;
}

Probably you can't get all cells in one array. But you can try to use the following:
let cellsArray: []
func tableView(_ tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
//Your data source methods
let cell = ......
....
cellsArray.append(cell)
}
This way you can get array of cells after view loads. I think there is no any other way to do that.
