[Swift] Let's use Segmented Control
I investigated how to use UISegmentedControl, so I wrote an article.
| Implementation environment | version |
|---|---|
| Swift | 5 |
| Xcode | 12.0 |
What is Segmented Control?
A literal translation of Segmented Control Control device (control) divided into parts </ b>
Take a look at the official Apple documentation!
Very concisely Multiple individual buttons that can be operated horizontally </ b>.
Easy to use
Select Attributes Inspector of Segmented Control,
Set the color when the button is selected with Selected Tint </ code>
Set the number of buttons with Segments </ code>
Set the button title with Title </ code>
Get the title of the selected button
python
@IBAction func segmentedControl(_ sender: UISegmentedControl) {
print(sender.titleForSegment(at: sender.selectedSegmentIndex)!)
}
When you want to change the button selected during viewload
python
class ViewController: UIViewController {
@IBOutlet weak var segmentedControl: UISegmentedControl!
override func viewDidLoad() {
super.viewDidLoad()
segmentedControl.selectedSegmentIndex = 1
}
SegmentIndex increases from the left with 0, 1, 2, ...
This time,
segmentedControl.selectedSegmentIndex = 1
So, since 1 </ code> is assigned, it is displayed like this after startup.
It seems that Segmented control can be set not only with characters but also with images, so if you are interested, please try it.
