Answer 1

(1). In this method cellForRowAtIndexPath: , assign button with a tag . For example:

cell.yourbutton.tag = indexPath.row;

(2). Add action for you button with same selector

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

(3). Then

-(void)cellButtonClicked:(UIButton*)sender
{
    NSIndexPath *path = [NSIndexPath indexPathForRow:sender.tag inSection:0];
}

Answer 2

You can define your custom property and you can use it like below:-

#define kCustomProperty @"CustomProperty" 

Associate your object with that custom property like below

objc_setAssociatedObject(yourButton,kCustomProperty , yourCellIndexPath, OBJC_ASSOCIATION_RETAIN_NONATOMIC);

Get your data using the same property and object like below

NSIndexPath *yourCellIndexPath = (NSIndexPath *)objc_getAssociatedObject(yourButton, kCustomProperty);

Its a kind of custom property you can create by coding if you don't want to use tag.
