切换到swift 2.0并得到AnyObject错误

Question

为什么我可以得到Cannot convert value of type [AnyObject]! to expected argument type.我试图加载nib到视图控制器。

func loadNibNamed(name: String!, owner: AnyObject!, options: [NSObject : AnyObject]!) -> [View1]!{
    NSBundle.mainBundle(loadNibNamed("View1", owner: self, options: nil)).lastObject
}

Answer 1

我认为这是正确的代码在Swift2.0

NSBundle.mainBundle()。loadNibNamed("View1"， owner: self, options: nil).last

lastObject是用于Swift1.2的，现在在swift2.0中不可用，请使用last。

要使用它，你可以把它转换成UIView

Answer 2

试试这个:

func loadNibNamed(name: String, owner: AnyObject, options: [NSObject : AnyObject]) -> [AnyObject] {
        return NSBundle.mainBundle().loadNibNamed(name, owner: owner, options: options)
}
