How to tell which rows toggle switch was changed



I have a tableview with the accessoryview of a toggle switch. I specify the section and the row and am having a difficult time determining which row was toggled. I used the toggleSwitch.tag to grab the indexRow but as my indexRow is part of an indexPath.section I am not sure how to tell which row I toggled.





Here is the code:







- (UITableViewCell *)tableAlert:(SBTableAlert *)tableAlert cellForRowAtIndexPath:(NSIndexPath *)indexPath {

UITableViewCell *cell;



Category *cat = [allCategories objectAtIndex:indexPath.section];

Subject *sub = [cat.subjects objectAtIndex:indexPath.row];



cell = [[[SBTableAlertCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease];

UISwitch *toggleSwitch = [[UISwitch alloc] init];

cell.accessoryView = [[UIView alloc] initWithFrame:toggleSwitch.frame];

[cell.accessoryView addSubview:toggleSwitch];



cell.textLabel.text =sub.title;

cell.detailTextLabel.text = sub.category_title;



if (sub.active==1){

[toggleSwitch setOn:YES];

} else {

[toggleSwitch setOn:NO];

}



toggleSwitch.tag = indexPath.row;



[toggleSwitch addTarget:self action:@selector(viewButtonPushed:) forControlEvents:UIControlEventValueChanged];

[toggleSwitch release];



return cell;



}





- (void)viewButtonPushed:(id)sender {

UIButton *button = (UIButton *)sender;

UITableViewCell *cell = button.superview; // adjust according to your UITableViewCell-subclass' view hierarchy

NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];



Category *cat = [allCategories objectAtIndex:indexPath.section];

Subject *sub = [cat.subjects objectAtIndex:indexPath.row];



selectedSubject = sub;



UISwitch* switchControl = sender;

NSLog( @"The switch is %@", switchControl.on ? @"ON" : @"OFF" );



if(switchControl.on){

[sub setActive:1];

NSLog(@"%@ is being set to ACTIVE", selectedSubject.title);

}else{

[sub setActive:0];

NSLog(@"%@ is being set to INACTIVE", selectedSubject.title);

}



[sub setIsDirty:YES];



[cat.subjects replaceObjectAtIndex:indexPath.row withObject:sub];



[sub autorelease];

[cat autorelease];



}







Here is my didSelectRowAtIndexPath. Do I need to have any reference to the toggleSwitch here?







- (void)tableAlert:(SBTableAlert *)tableAlert didSelectRowAtIndexPath:(NSIndexPath *)indexPath {



Category *cat = [allCategories objectAtIndex:indexPath.section];

Subject *sub = [cat.subjects objectAtIndex:indexPath.row];



selectedSubject = sub;

NSLog(@"selectedSubject = %@", selectedSubject.title);





if (tableAlert.type == SBTableAlertTypeMultipleSelct) {

UITableViewCell *cell = [tableAlert.tableView cellForRowAtIndexPath:indexPath];

if (cell.accessoryType == UITableViewCellAccessoryNone)

[cell setAccessoryType:UITableViewCellAccessoryCheckmark];

else

[cell setAccessoryType:UITableViewCellAccessoryNone];



[tableAlert.tableView deselectRowAtIndexPath:indexPath animated:YES];

}



}

  1. I have found that you need to go to the superview of the superview of the item in the cell (assuming that the button or control is right off the root of the cell) in order to get the pointer to the cell.

    Try this instead:

    UITableViewCell *cell = button.superview.superview;


    and see if the results are any better. Check out my blog post on this for more information:

    Two superviews are better than one

div not scrolling properly with slimScroll plugin

I am using the slimScroll plugin for jQuery by Piotr Rochala Which is a great plugin for nice scrollbars on most browsers but I am stuck because I am using it for a chat box and whenever the user appends new text to the boxit does scroll using the .scrollTop() method however the plugin's scrollbar doesnt scroll with it and when the user wants to look though the chat history it will start scrolling from near the top. I have made a quick demo of my situation http://jsfiddle.net/DY9CT/2/ Does anyone know how to solve this problem?

Why does this javascript based printing cause Safari to refresh the page?

The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
