DZNEmptyDataSet is a library that makes it extremely easy to add custom "empty" data sets, for when a screen in your app either currently has no data, or the user hasn’t created any data yet.
You can configure it by implementing a bunch of different optional methods in the DZNEmptyDataSet
protocol. A pretty simple setup is shown here, but the there are lots of more advanced options including custom views and even easily adding a button below the text.
extension PhotosViewController : DZNEmptyDataSetSource {
func titleForEmptyDataSet(scrollView: UIScrollView!) -> NSAttributedString! {
return NSAttributedString(string: "No Photos")
}
func descriptionForEmptyDataSet(scrollView: UIScrollView!) -> NSAttributedString! {
let text = "Photos you take will appear here"
return NSAttributedString(string: text, attributes: [
NSForegroundColorAttributeName: UIColor.grayColor()
])
}
func imageForEmptyDataSet(scrollView: UIScrollView!) -> UIImage! {
return UIImage(named: "cracked-egg")
}
}
Detect interaction by implementing one of the methods in the DZNEmptyDataSetDelegate
protocol.
extension PhotosViewController : DZNEmptyDataSetDelegate {
func emptyDataSetDidTapButton(scrollView: UIScrollView!) {
println("tapped button on the empty view!")
}
}
Here's some example empty screens DZNEmptyDataSet can help you create:
