我做到了这一点,它回答了我的文字没有问题:
class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {
@IBOutlet weak var foodLabel: UILabel!
@IBOutlet weak var foodSlider: UIPickerView!
var picker = UIPickerView()
let foodsScroll = ["pizza \npepperoni" ,"chicken \nnuggets ","meat \nballs","hamburger \nbloody","omelette \ngrilled","ice cream \nberry"]
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, rowHeightForComponent component: Int) -> CGFloat {
return 80.00
}
func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {
let cgRect = CGRect(x: 0.00, y: 0.00, width: 400, height: 200)
let label = UILabel(frame: cgRect)
label.lineBreakMode = .byWordWrapping
label.numberOfLines = 0
label.text = foodsScroll[row]
label.sizeToFit()
return label
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return foodsScroll[row]
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return foodsScroll.count
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
foodLabel.text = foodsScroll[row]
}
override func viewDidLoad() {
}
}
它涉及到我需要在每个食物名称的一侧添加单个图标的部分。我无法弄清楚它是如何完成的,但我知道你可以使用两种简单的方法:
也欢迎任何替代方法。

你是问题,你就是答案是的!!这里有两个简单的方法来添加你的想法 1)使用额外的UIView和 2)使用UIImage。 3)创建一张卡片 最后,这是一张卡片。但它与UIView相同
