如何添加的UIImage到uipickerview编程SWIFT 3

Question

我编程在控制器中创建UIPickerView，我需要将图像添加到UIPickerView与相应的标签。当我创建UIImageView编程，并添加到UIPickerView错误来了说，UIImage不能添加到UIPickerView。

我该如何解决这个问题。在此先感谢

Answer 1

func pickerView(pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusingView view: UIView!) -> UIView { 

    var myView = UIView(frame: CGRectMake(0, 0, pickerView.bounds.width, 60)) 

    var ImageView = UIImageView(frame: CGRectMake(0, 0, pickerView.bounds.width, 50)) 

    var row = String() 
    switch row { 
    case 0: 
     row = “animal1” 
     ImageView.image = UIImage(named:"animal1.jpg") 
    case 1: 
     row = “animal2” 
     ImageView.image = UIImage(named:"animal2.jpg") 
    case 2: 
     default: 
     rowString = "Error: too many rows" 
     ImageView.image = nil 
    } 
    myView.addSubview(ImageView) 

    return myView 
}

在斯威夫特3，试试下面的代码：

func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView { 
    let myView = UIView(frame: CGRect(x: 0, y: 0, width: pickerView.bounds.width - 30, height: 60)) 
    let myImageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 50, height: 50)) 
    var rowString = String() 
    switch row { 
    case 0: 
     rowString = "Washington" 
     myImageView.image = UIImage(named:"washington.jpg") 
    case 1: 
     rowString = "Beijing" 
     myImageView.image = UIImage(named:"beijing.jpg") 
    case 2: break 
    default: 
     rowString = "Error: too many rows" 
     myImageView.image = nil 
    } 
    let myLabel = UILabel(frame: CGRect(x: 60, y: 0, width: pickerView.bounds.width - 90, height: 60)) 
    myLabel.text = rowString 

    myView.addSubview(myLabel) 
    myView.addSubview(myImageView) 
    return myView 
}
