如何将UIImage放入AnyObject数组？

Question

在Xcode 6 beta 7中，我无法在AnyObject数组中放置UIImage：

var objects = [pizzaImage.image, title, ingredients.text]

错误： Cannot convert the expression's type 'Array' to type 'ArrayLiteralConvertible“

beta 6中没有问题

修改 这是完整的代码，尝试了一切，但是没有运气：

var objects = [pizzaImage.image!, title, ingredients.text!]]
var act = UIActivityViewController(activityItems: objects, applicationActivities: nil)
self.presentViewController(act, animated: true, completion: nil)

Answer 1

解决：

var objects = [pizzaImage.image!, title!, ingredients.text]]
var act = UIActivityViewController(activityItems: objects, applicationActivities: nil)
self.presentViewController(act, animated: true, completion: nil)

但是如果你只输入标题和textField，那么编译器就没有什么可抱怨的了：

var objects = [title, ingredients.text]

为什么？ 这真的不清楚......
