swift 使用计算属性+结构管理内存

class GooClass {

deinit {

print("aaaaaaaa")

}

var str = "gooClass"

}

struct GooStruct {

var goo = GooClass()

}

extension ViewController{

var gooStruct:GooStruct {

get {

return GooStruct()

}

}

}

class ViewController: UIViewController {

override func viewDidLoad() {

super.viewDidLoad()

// Do any additional setup after loading the view, typically from a nib.

print(self.gooStruct.goo.str)

}

}
