如何在 Swift 的 outlet 集合中将所有标签添加到标签数组的边框？
How to add a border all labels to an array of labels in an outlet collection in Swift?
class ViewController: UIViewController {
@IBOutlet var labels: [UILabel]!
override func viewDidLoad() {
super.viewDidLoad()
labels[0].layer.borderWidth = 1
labels[0].layer.borderColor = UIColor.black.cgColor
}
}
您可以loop通过labels并设置border如下，
labels.forEach { (label) in
label.layer.borderColor = UIColor.black.cgColor
label.layer.borderWidth = 1.0
}
