UITableViewCell turns blue when scrolling
I am getting a really strange error and I can't figure out how to fix it: When I scroll around in my UITableView it will sometimes highlight a cell blue, even when I don't fully selected.
For example:
-Cell 1- -Cell 2- -Cell 3- -Cell 4- If I put my finger down on Cell 2 and scroll to Cell 4 it will leave Cell 2 highlighted, even though didSelectRowAtIndexPath: is never fired.Any ideas?
EDIT Added code:
UITableViewCell *cell = nil;
static NSString *cellId = @"StyleDefault";
cell = [tableView dequeueReusableCellWithIdentifier:cellId];
if (cell == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellId] autorelease];
}
cell.textLabel.text = @"Cell One";
cell.textLabel.t开发者_StackOverflow中文版extAlignment = UITextAlignmentCenter;
[cell setAccessoryView:nil];
return cell;
FIXED IT!
My solution was two parts:
1) In cellForRowAtIndexPath: put "cell.selected = NO;", which fixes the problem of if the cell gets touched down on then goes off screen (scrolling).
UITableViewCell *cell = nil;
static NSString *cellId = @"StyleDefault";
cell = [tableView dequeueReusableCellWithIdentifier:cellId];
if (cell == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellId] autorelease];
}
cell.textLabel.text = @"Cell One";
cell.textLabel.textAlignment = UITextAlignmentCenter;
[cell setAccessoryView:nil];
//Here:
cell.selected = NO;
return cell;
2) Put "[tableView deselectRowAtIndexPath:indexPath animated:YES];" into didSelectRowAtIndexPath: instead of what I used to have "[[tableView cellForRowAtIndexPath:indexPath] setSelected:NO];" which was wrong on so many levels.
[tableView deselectRowAtIndexPath:indexPath animated:YES];
Hopefully that helps others that have this issue. Case closed.
You can use following while creating cell.
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell = Your allocation.
cell.selectionStyle = UITableViewCellSelectionStyleNone;
I guess you need to also please have look at the UIViewTable Property for Touch i.e. Delay Content Touches and Cancellable Content Touches.
Hope this helps.
Override -tableView:willSelectRowAtIndexPath: in your UITableView delegate, and return nil for everything just to make sure you're not allowing it to select the rows.
