我想用動物列表做一個swift項目,然後當你點擊其中一行時,你會被運送到另一個窗口它告訴你動物的描述。Swift xcode錯誤:類型'DetailViewController'的值沒有成員'Animal'
這裏是代碼,如果截圖太小:
import UIKit
class DetailViewController: UIViewController
{
@IBOutlet weak var titleLabel: UILabel!
@IBOutlet weak var descriptionLabel: UILabel!
var animal: Animal?
var a = Animal?()
override func viewWillAppear(animated: Bool)
{
titleLabel.text = a!.name
descriptionLabel.text = a!.longDescription
}
override func viewDidLoad()
{
viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning()
{
didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
ListOfAnimals類代碼:
import Foundation
let animals = [
ListOfAnimals(name: "Cow",
shortDescription: "Cattle",
longDescription: "A cow is a mature female and bull of an adult male of a bovine family. A heifer is a female cow that hasn't had a calf yet. Cattle is the name for the whole cow family. THere are about 920 different breeds of cows in the world."),
ListOfAnimals(name: "Bird",
shortDescription: "Usually small, has wings, feathers, and can fly.",
longDescription: "A warm-blooded egg-laying vertebrate distinguished by the possession of feathers, wings, and a beak and (typically) by being able to fly."),
ListOfAnimals(name: "Dolphin",
shortDescription: "A large fish",
longDescription: "A small gregarious toothed whale that typically has a beaklike snout and a curved fin on the back. Dolphins have become well known for their sociable nature and high intelligence."),
ListOfAnimals(name: "Dog",
shortDescription: "Man's best friend",
longDescription: "A domesticated carnivorous mammal that typically has a long snout, an acute sense of smell, and a barking, howling, or whining voice. It is widely kept as a pet or for work or field sports."),
ListOfAnimals(name: "Zebra",
shortDescription: "A horse with white and black stripes",
longDescription: "an African wild horse with black-and-white stripes and an erect mane."),
]
class ListOfAnimals
{
var name: String
//var type: Type
var shortDescription: String
var longDescription: String
init(name: String, shortDescription: String, longDescription: String)
{
self.name = name
self.shortDescription = shortDescription
self.longDescription = longDescription
}
}
是工作,但現在我得到一個跟蹤誤差強調了「動物[indexPath.row]」和錯誤說「不能標a類型爲'[ListOfAnimals]'的值' – David
