Answer 1

Here is Objective-C version:

- (void) playPauseAction:(id)sender {

    UIButton *button = (UIButton *)sender;

    if ([button.currentTitle isEqualToString:@"Play"]) {
        [button setTitle:@"Pause" forState:UIControlStateNormal];
        // Playing code
    } else {
        [button setTitle:@"Play" forState:UIControlStateNormal];
        // Pausing code
    }
}

Answer 2

Try this

In your cellForRowAtIndexPath

   UIButton *button = [[UIButton alloc]initWithFrame:Your Frame];
   [button addTarget:self action:@selector(ButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
   Button.tag = indexPath.row;
    [cell.contentView addSubview:Button];

Then write ButtonClicked method

-(void)ButtonClicked:(UIButton*)button{
      if (button.tag == 0)
      {
             //Here button at 0th row is selected.
            //Write your code here
      }
}

Hope it helps.

1) In your cellForRowAtIndexPath: method, assign button tag as index:

cell.yourbutton.tag = indexPath.row;

2) Add target and action for your button as below:

[cell.yourbutton addTarget:self action:@selector(yourButtonClicked:) forControlEvents:UIControlEventTouchUpInside];

3) Code actions based on index as below in ViewControler:

-(void)yourButtonClicked:(UIButton*)sender
{
     Bool cicked=1;
     if(clicked)
     {
       [cell.yourbutton setTitle: @"myTitle" forState:@""]; 
     }

}

1.Add TargetAction to the button as

[btn addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];

2.Just follow action method like this

-(void)buttonClicked:(UIButton*)btn
    {
        if ([btn.titleLabel.text isEqualToString:@"Play"]) {
            [btn setTitle:@"Stop" forState:UIControlStateNormal];
        }else{
             [btn setTitle:@"Play" forState:UIControlStateNormal];
        }
    }
