＆QUOT;不能分配给物业：＆QUOT;任何＆QUOT;是不可改变的＆QUOT;错误 [英] "Cannot assign to property: "any" is immutable" error

问题描述

tiledViewsStack 包含的UIImageViews。我试图给数组的新中心坐标中的每个的UIImageView。不知道为什么我得到这个错误在for循环......

  VAR tiledViewsStack = [AnyObject]（）    VAR randLocInt = INT（）
    VAR randLoc = CGPoint（）    在tiledViewsStack任何变种
    {
        randLocInt = INT（（arc4random（）* 10）％9）// 0，--- 8
        randLoc = allCenters [randLocInt] .CGPointValue（）
        any.center = randLoc
    }
 

解决方案

需要做出 tiledViewsStack UIImages，不AnyObjects一叠。改变 VAR tiledViewsStack = [AnyObject]（）到 VAR tiledViewsStack = [UIImageView的（）。

tiledViewsStack contains UIImageViews. I'm trying to give each UIImageView in the array a new center coordinate. Not sure why I'm getting this error for the last line in the for loop...

    var tiledViewsStack = [AnyObject]()

    var randLocInt = Int()
    var randLoc = CGPoint()

    for var any in tiledViewsStack
    {
        randLocInt = Int((arc4random()*10) % 9) // 0, --- 8
        randLoc = allCenters[randLocInt].CGPointValue()
        any.center = randLoc
    }

解决方案

Needed to make tiledViewsStack a stack of UIImages, not AnyObjects. Changed var tiledViewsStack = [AnyObject]() to var tiledViewsStack = [UIImageView]().
