objective-c - 合适的 View 按钮 Action

Question

在我的表格 View 中，我在每个单元格中都有一个按钮

UIButton *editButton = [UIButton buttonWithType:UIButtonTypeCustom];
editButton.frame = CGRectMake(281,0, 20, 50);
UIImage *editButtonImage = [UIImage imageNamed:@"edit.png"];
[editButton setImage:editButtonImage forState:UIControlStateNormal];
[editButton setBackgroundColor:[UIColor clearColor]];
[editButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[editButton addTarget:self action:@selector(editButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:editButton];

按钮 Action 是这样的

-(IBAction)editButtonAction:(id)sender{
     UIButton *btn = (UIButton*) sender;
     UITableViewCell *cell = (UITableViewCell*) btn.superview.superview;
     NSIndexPath *indexPath =[self.table indexPathForCell:cell]; 
     int row = indexPath.row;
     NSLog(@"Selected row is: %d",row);
}

当我在表格 View 中单击按钮时，选定的行是总是给出 0有什么想法吗？和任何代码

editButton.tag = indexPath.row;
[editButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[editButton addTarget:self action:@selector(editButtonAction:) forControlEvents:UIControlEventTouchUpInside];

-(IBAction)editButtonAction:(id)sender{
UIButton *btn = (UIButton*) sender;
NSLog(@"Selected row is: %d",btn.tag);
}
