Part 3 - UIView's Tag Property

The Tag property is a number and when used with the corresponding viewWithTag function one can access a specific subview without the need for an outlet.

Example

 
override func viewDidLoad() {
    super.viewDidLoad()
    
    let label = view.viewWithTag(1) as! UILabel
    label.text = "New text here"
}
 

Observations

• You can give the same Tag to multiple views
• The first view in the document outline matching the Tag number is selected when viewWithTag is used
