func

NSIndexPath){

       

alert(str[indexPath.row])

   
}

   

//侧滑选项

   

func

//返回cell高度

}

 

}

 

 

 
 

 

TableViewCell代码

 

import
UIKit

 

class
TableViewCell:
UITableViewCell
{

 

 

   

@IBOutlet
weak
var
title:
UILabel!

   

   

override
func
awakeFromNib() {

       

super.awakeFromNib()

       

// Initialization code

   
}

 

   

override
func
setSelected(selected:
Bool,
animated:
Bool)
{

       

super.setSelected(selected,
animated: animated)

 

       

// Configure the view for the selected state

   
}

 

}
 

补充
设置cell没有点击效果

cell.selectionStyle = UITableViewCellSelectionStyle.None
