TableView rounded corners and shadow

问题

I have a tableview with three rows. I am trying to make the table rows have rounded corners and also a shadow effect around the entire tableview. For some reason, I cannot make the tableview both have the rounded corners and shadow effect but I could do them separately if I comment out the code responsible for one of the features. Here is the code I am using:

//this is for shadow effect

tableView.backgroundColor = UIColor.clearColor()

tableView.layer.shadowColor = UIColor.darkGrayColor().CGColor   

tableView.layer.shadowOffset = CGSize(width: 2.0, height: 2.0

tableView.layer.shadowOpacity = 1.0

tableView.layer.shadowRadius = 2

// This is for rounded corners

tableView.layer.cornerRadius = 10

tableView.layer.masksToBounds = true

You can add your table view to a container view and add drop shadow to that container view:

let containerView:UIView = UIView(frame:CGRect(x: 10, y: 100, width: 300, height: 400))
self.tableView = UITableView(frame: containerView.bounds), style: .Plain)
containerView.backgroundColor = UIColor.clearColor()
containerView.layer.shadowColor = UIColor.darkGrayColor().CGColor   
containerView.layer.shadowOffset = CGSize(width: 2.0, height: 2.0)
containerView.layer.shadowOpacity = 1.0
containerView.layer.shadowRadius = 2
// This is for rounded corners
self.tableView.layer.cornerRadius = 10
self.tableView.layer.masksToBounds = true
self.view.addSubview(containerView)
containerView.addSubview(self.tableView)

Edit

Swift 3.0:

let containerView:UIView = UIView(frame:CGRect(x: 10, y: 100, width: 300, height: 400))
self.tableView = UITableView(frame: containerView.bounds, style: .plain)
containerView.backgroundColor = UIColor.clear
containerView.layer.shadowColor = UIColor.darkGray.cgColor
containerView.layer.shadowOffset = CGSize(width: 2.0, height: 2.0)
containerView.layer.shadowOpacity = 1.0
containerView.layer.shadowRadius = 2

self.tableView.layer.cornerRadius = 10
self.tableView.layer.masksToBounds = true
self.view.addSubview(containerView)
containerView.addSubview(self.tableView)

The RDC's answer is good, but for me the result didnt resolve my case, follow is my fix :

//for table view border
tableView.layer.borderColor = UIColor .grayColor().CGColor
tableView.layer.borderWidth = 1.0

//for shadow
let containerView:UIView = UIView(frame:self.tableView.frame)
//dont use clear color,fit blue color
containerView.backgroundColor = UIColor.blueColor()
//shadow view also need cornerRadius
containerView.layer.cornerRadius = 10
containerView.layer.shadowColor = UIColor.lightGrayColor().CGColor
containerView.layer.shadowOffset = CGSizeMake(-10, 10); //Left-Bottom shadow
//containerView.layer.shadowOffset = CGSizeMake(10, 10); //Right-Bottom shadow
containerView.layer.shadowOpacity = 1.0
containerView.layer.shadowRadius = 2

//for rounded corners
tableView.layer.cornerRadius = 10
tableView.layer.masksToBounds = true
self.view.addSubview(containerView)
self.view.addSubview(tableView)

Thanks to @beyowulf

I have upgraded for me with Swift 2.2, to

• set Border,
• Rounded corner and

• Drop shadow to the table view

  //for table view border
  tableView.layer.borderColor = UIColor .grayColor().CGColor
  tableView.layer.borderWidth = 1.0
  
  //for shadow
  let containerView:UIView = UIView(frame:self.tableView.frame)
  containerView.backgroundColor = UIColor.clearColor()
  containerView.layer.shadowColor = UIColor.lightGrayColor().CGColor
  containerView.layer.shadowOffset = CGSizeMake(-10, 10); //Left-Bottom shadow
  //containerView.layer.shadowOffset = CGSizeMake(10, 10); //Right-Bottom shadow
  containerView.layer.shadowOpacity = 1.0
  containerView.layer.shadowRadius = 2
  
  //for rounded corners
  tableView.layer.cornerRadius = 10
  tableView.layer.masksToBounds = true
  self.view.addSubview(containerView)
  containerView.addSubview(tableView)
  

result looks like
