swift - 如何声明数组并在同一行添加项目？

Question

我想声明一个自定义类型数组并添加几个项目。

class ClassA:NSObject {
  var property1: String?
  var property2: String?
}

var myarray = [ClassA]()

如何在与上述声明相同的行中将 ClassA 的新实例添加到数组中？

您可以像这样添加自定义初始化器并在数组上使用类型推断:

class ClassA: NSObject {
    var property1: String?
    var property2: String?

    init(property1: String, property2: String) {
        super.init()
        self.property1 = property1
        self.property2 = property2
    }
}

// ...

var myarray = [
    ClassA(property1: "A1", property2: "B1"),
    ClassA(property1: "A2", property2: "B2"),
    ClassA(property1: "A3", property2: "B3"),
    ClassA(property1: "A4", property2: "B4"),
]
