get section number and row number on custom cells button click?

Closed 9 years ago.
In my code I have a table view with many sections sorted alphabetically. I have checkboxes(UIButton) in table rows and I need check them according to respective status entered in row. I had done
checkbutton.tag = indexpath.row;
but when table scrolls and section get changed and I get status of previous section in my checkbox method. anyone please help me on this.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
CheckButton = [UIButton buttonWithType:UIButtonTypeCustom];
[CheckButton addTarget:self action:#selector(CheckBoxAction:) forControlEvents:UIControlEventTouchUpInside];
CheckButton.tag=indexPath.row;
//some other stuff
[cell.contentView addSubview:CheckButton];
}
and this my CheckBoxAction
-(void)CheckBoxAction:(UIButton *)btn
{
tag = btn.tag;
NSDictionary *tagdict =[statusArray objectAtIndex:tag];
}
Now, problem is that indexpath.row is 0 whenever section is changed, so I can't able to access exact row number in my CheckBoxAction.

Answer 1

use this for getting current row you tap.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
CheckButton = [[UIButton alloc] init];
[CheckButton addTarget:self action:#selector(CheckBoxAction:) forControlEvents:UIControlEventTouchUpInside];
CheckButton.tag=indexPath.row;
[cell addSubview:CheckButton];
}
-(void)CheckBoxAction:(id)sender
{
// Cast Sender to UIButton
UIButton *button = (UIButton *)sender;
// Find Point in Superview
CGPoint pointInSuperview = [button.superview convertPoint:button.center toView:self.tableView];
// Infer Index Path
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:pointInSuperview];
// Log to Console
NSLog(#"selected Row : %d", indexPath.row);
}

// Try this
CheckButton.tag = [[NSString stringWithFormat:#"%d%d",indexPath.section,indexPath.row] integerValue];

What you are doing is wrong in many ways. So, I am not going to give you a solution for the exact problem you have, but more of a guideline:
First you are adding the checkbox directly to the cell, which means you are possible adding multiple CheckButton to the same cell, if you scroll your UITableView a few times.
Add the checkButton on the cell directly instead of keep adding it in the cellForRowAtIndexPath, this can give you a performance boost.
Use a block that will be executed when a user clicks the button. This way you are able to capture the context of your UIViewController. You should assign that block to the cell on cellForRowAtIndexPath
