Blur and vibrancy effects on UITableView - ios

Question

I just don't know how to do that. I've tried everything from Stackoverflow and nothing worked. I have a view, image and below all of that tableView in my hierarchy. But table view is still white. Is there somebody who knows how to do this? As I wrote, nothing from here worked.
I want to have this kind of UITableView:
Navigation bar is part of my question too (his blur and vibrancy).
After use of this code:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell
let backgroundImageView = UIImageView(image: UIImage(named: "background3.png"))
cell.backgroundView = backgroundImageView
var visualEffectView = UIVisualEffectView(effect: UIBlurEffect(style: .Light)) as UIVisualEffectView
visualEffectView.frame = CGRectMake(0, 0, cell.bounds.width, cell.bounds.height)
backgroundImageView.addSubview(visualEffectView)
cell.textLabel?.text = self.field[indexPath.row]
cell.textLabel?.textColor = UIColor.whiteColor()
cell.textLabel?.backgroundColor = UIColor.clearColor()
return cell
}
My tableView now look like this:
And that is logical, because it is the look of the background3.png image.

Subclass UITableViewController.
let effect = UIBlurEffect(style: .Dark)
let resizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight
Build a background view like this and stick it into your table view. Notice separator effect, which is new api.
override func viewDidLoad() {
super.viewDidLoad()
let backgroundView = UIView(frame: view.bounds)
backgroundView.autoresizingMask = resizingMask
backgroundView.addSubview(self.buildImageView())
backgroundView.addSubview(self.buildBlurView())
tableView.backgroundView = backgroundView
tableView.separatorEffect = UIVibrancyEffect(forBlurEffect: effect)
}
func buildImageView() -> UIImageView {
let imageView = UIImageView(image: UIImage(named: "coolimage"))
imageView.frame = view.bounds
imageView.autoresizingMask = resizingMask
return imageView
}
func buildBlurView() -> UIVisualEffectView {
let blurView = UIVisualEffectView(effect: effect)
blurView.frame = view.bounds
blurView.autoresizingMask = resizingMask
return blurView
}
Change background colour of cell to clear, so background is visible when you have cells.
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath)as! UITableViewCell
cell.backgroundColor = UIColor.clearColor()
return cell
}

So the solution is really simple. I've find a great tutorial on Youtube:
Swift iOS tutorial - Custom tableview appearance in Xcode 6
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell
var openSansSemibold = UIFont(name: "OpenSans-Semibold", size: 12)?.fontDescriptor().fontDescriptorWithSymbolicTraits(UIFontDescriptorSymbolicTraits.TraitBold)
cell.textLabel?.font = UIFont(descriptor: openSansSemibold!, size: 12)
if(indexPath.row % 2 == 1){
cell.backgroundColor = UIColor.clearColor()
}else{
cell.backgroundColor = UIColor.whiteColor().colorWithAlphaComponent(0.2)
cell.textLabel?.backgroundColor = UIColor.whiteColor().colorWithAlphaComponent(0.0)
cell.detailTextLabel?.backgroundColor = UIColor.whiteColor().colorWithAlphaComponent(0.0)
}
cell.textLabel?.textColor = UIColor.whiteColor()
return cell
}
In viewDidLoad() method:
self.tableView.rowHeight = 70
self.tableView.backgroundView = UIImageView(image: UIImage(named: "background"))
And that is it. Every odd cell has clear color, every even has blurred background. It looks really great!
