Question

Edit: This post is kinda long so the end question is copied here:

So obviously it is not checking the cell I am clicking, it is checking a
new cell that it is creating. How would I go about checking the cell
that is clicked, and checking the content that is in that specific
cell (i.e. checking the text of that cell’s label).

So in InterfaceBuilder I have a prototype cell, and I do the following code to create a number of cells ina uitableview

//tableview datasource delegate methods
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    return 1;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return cellIconNames.count;
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

static NSString *CellIdentifier = @"Cell";

cellIconName = [cellIconNames objectAtIndex:indexPath.row];


NSString *cellIconImageName = [[self cellIconImages] objectAtIndex:[indexPath row]];

CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];


if(cell == nil){
    cell = [[CustomCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.rightLabel.text = [cellIconNames objectAtIndex:indexPath.row];
cell.carrierImage.image = [UIImage imageNamed:cellIconImageName];

urlString = [cellButtons objectAtIndex:indexPath.row];

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0, 0, 290, 88);
[button setTitle:@"" forState:UIControlStateNormal];
[button addTarget:self action:@selector(startCarrierSite:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button];
[cell.contentView bringSubviewToFront:button];

return cell;
}

So basically what I did is made an imageview, a label, and a seethrough button on each cell, and made the respective images and labels say different things according to an array.

The button I have in each cell points to the same selector, startCarrierSite:

This is the method for startCarrierSite

-(IBAction)startCarrierSite:(CustomCell *)cell;{

UILabel *rightLabel = (UILabel*) [cell.subviews objectAtIndex:0];

NSString *labelText = rightLabel.text;

if(labelText == @"Aetna"){
    NSURL *url = [NSURL URLWithString:@"www.aetna.com"];
    [[UIApplication sharedApplication] openURL:url];
}else{
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"www.google.com"]];
    }
}

What I am trying to do is check the label of the cell, and if the .text of that label is equal to a certain string, I run the code for opening safari and blah blah blah, thats not the issue.

The issue is that I can’t seem to check the labels in a cell. The current way I am trying to do this is by running the action with the argument of CustomCell (which is a child of the UITableViewCell class).

This works and the cell is checked when you click it, but then I go to check the text of the label and it crashes. I’m getting the error

Terminating app due to uncaught exception ‘NSRangeException’, reason: ‘* -[__NSArrayI objectAtIndex:]: index 4294967295 beyond bounds for empty array’

So obviously it is not checking the cell I am clicking, it is checking a new cell that it is creating. How would I go about checking the cell that is clicked, and checking the content that is in that specific cell (i.e. checking the text of that cell’s label).

EDIT (ADDING IN UPDATED METHOD):

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

CustomCell *cell = (CustomCell*)[tableView cellForRowAtIndexPath:indexPath];

if ([cell.urlString isEqualToString:@"Aetna"]) {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"www.aetna.com"]];
}else if([cell.urlString isEqualToString:nil]){
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"www.google.com"]];
    }

}

Answer 1

Use this UITableViewDelegate method:

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

From there you can access the cell with [tableView cellForRowAtIndexPath:indexPath]

EDIT

Also, do not compare strings with yourString == @"someString".

Use [yourString isEqualToString:@"someString"].

*EDIT 2 *

Add a property to your CustomCell

@property (nonatomic) NSString *urlString;

Set the property when you are creating the cell, and then in the didSelectRowAtIndexPath method, do this;

CustomCell *cell = (CustomCell*)[tableView cellForRowAtIndexPath:indexPath];

Now the URL is simply cell.urlString.
