Question

问题：我正在寻找的是在表格中显示这些信息，所以我认为我需要：

MyHouses1 [第] [行] .getAddressDetails（）

如何正确定义MyHouses1？

    import UIKit

class House {
    var address = "Address"
    var street = "Street"
    var city = "City"
    var state = "State"
    var zip = "Zip"

    func getAddressDetails() -> String {
        return "\(address) \(street) \(city) \(state) \(zip)"
        //return "\(address) \(street)"
    }
    func getCityState() -> String {
        return "\(city) - \(state)"
    }
}

class newhouse: House {
    var lighting = "crappy"
    var plumbing = "sucks"
    var heating = "heats good"
    var cooling = "cools good"
    var repairs = "needs alot of repairs"

    func getFixtureDetails() -> String {
        return "\(lighting) \(plumbing) \(heating) \(cooling)"
    }
}

// THIS WORKS
var MyHouses: [newhouse] = [] 
MyHouses.append(newhouse())  
MyHouses[0].address = "test" 
MyHouses[0].getAddressDetails() 


// THIS DOESN'T WORK 

var MyHouses1: [[newhouse]] = [] // No Error Yet
MyHouses1.append // Getting an error here, not sure how to append

你可以这样做..

var MyHouses1: [[newhouse]] = []// No Error Yet
var houses = [newhouse]() //Initialize your `newhouse` array here

for i in 0...4 {
    houses += [newhouse()]
}

MyHouses1 += [houses] 

print("\(MyHouses1[0][0].city)") // will print "City"

使用多维属性定义对象
