Tableview Cell requires two taps to reveal the view - ios

Question

I had a problem with table view didSelect method and prepareForSegue. I used SWRevealController in my app. While selecting cell it reveals the view. Sometimes it not worked properly. It takes two taps to reveal the view. A few months back I used old reveal view frame which contains perform block action. Its worked perfectly.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
for (int i=0; i<6; i++)
{
UITableViewCell *cell = [self tableView:tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:0]];
if (i == indexPath.row)
{
cell.contentView.backgroundColor = [UIColor colorWithRed:KColorRedSelected green:KColorGreenSelected blue:KColorBlueSelected alpha:1];
}
else
{
cell.contentView.backgroundColor = [UIColor colorWithRed:KColorRed green:KColorGreen blue:KColorBlue alpha:1];
}
}
}

Answer 1

Add this code inside of didSelectRowAtIndexPath and didDeselectRowAtIndexPath functions
dispatch_async(dispatch_get_main_queue(), ^{
//Write code what you need
});
That works for me.

The problem is with this line
[self tableView:tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:0]];
You are calling the delegate method, which dequeues a reusable cell (I assume, since it's standard behavior). You do not want to dequeue a reusable cell, you want to do something with a cell that is currently displayed at indexPath. To do that use method from UITableView
[tableView cellForRowAtIndexPath:indexPath];
The full code
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// grab the selected cell and give it selected color
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
cell.contentView.backgroundColor = [UIColor colorWithRed:KColorRedSelected green:KColorGreenSelected blue:KColorBlueSelected alpha:1];
}
- (void)tableView:(UITableView*)tableView didDeselectRowAtIndexPath:(NSIndexPath*)indexPath
{
// grab the deselected cell (if it's still visible) and give it deselected color
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
cell.contentView.backgroundColor = [UIColor colorWithRed:KColorRed green:KColorGreen blue:KColorBlue alpha:1];
}
You will also need to set appropriate color in UITableViewDelegate method cellForRowAtIndexPath, since the color you once set will stay in the cell when it's reused.

Answer 3

This s completely wrong method to get clicked cell
UITableViewCell *cell = [self tableView:tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:0]];
And don't use for loop as well. instead of this you should use
UITableViewCell *cell = [tableView cellForIndexPath:indexPath];
to get correct cell.
