How to select single button on UITableView - ios

Question

I have an issue in an UITableView as I need to place a button on each row of the tableview and if i click the button, it gets selected at a time and selecting is like toggle. How to achieve this, please help me out to solve this problem.
Below is the following code that am trying to get it out. I am creating button on cellForRowAtIndexPath as shown below:
UIButton *Btn = [[UIButton alloc]init];
Btn .frame = CGRectMake(3, 10, 33, 30);
[Btn setImage:[UIImage imageNamed:#"deselect.png"] forState:UIControlStateNormal];
[Btn addTarget:self action:#selector(method:) forControlEvents:UIControlEventTouchUpInside];
Btn.tag=indexPath.row;
[cell.contentView addSubview:Btn];
and the method: for button action:
-(void)method:(UIButton*)sender
{
NSIndexPath *indexpath1 = [NSIndexPath indexPathForRow:sender.tag inSection:0];
Btn = (UIButton *)sender;
//Btn.tag=sender.tag;
[Btn setImage:[UIImage imageNamed:#"select.png"] forState:UIControlStateNormal];
}

Answer 1

You have an array to store whether the button of a cell is selected or not. In the cellForRowAtIndexPath method, you should set 2 images for 2 states UIControlStateNormal and UIControlStateSelected of the button:
[Btn setImage:[UIImage imageNamed:#"select.png"] forState:UIControlStateSelected];
[Btn setImage:[UIImage imageNamed:#"deselect.png"] forState:UIControlStateNormal];
Then in the method: function, you switch the state of the button via Btn.selected based on the value in the array.

Answer 2

UIImage * btnLinkNormal = [UIImage imageNamed:#"select.png"];
[cell.linkButton setImage:btnLinkNormal forState:UIControlStateNormal];
// Add image to button for pressed state
UIImage * btnLinkHighlighted = [UIImage imageNamed:#"deselect.png"];
[cell.linkButton setImage:btnLinkHighlighted forState:UIControlStateHighlighted];
