Question

我正在制作日视图日历，就像本机iPhone日历一样。我试图将瓷砖与原生日历中的瓷砖相同放置，如果它们的大小和时间相同。

但是，我只能弄清楚如何对2个瓷砖而不是多个瓷砖。在附图中我有4个瓷砖。一个稍微扩展到另一个3.然后我在最左边有第一个瓷砖，第二个瓷砖在第一个瓷砖之后。现在我需要弄清楚如何添加额外的瓷砖？

我如何为2个以上的瓷砖做这个？

关于图像：如果你看不到第三块瓷砖在第二块瓷砖的顶部（你可以看到它有点暗，因为它们在彼此的顶部。

Answer 1

看来你的测试

if ((selectedView.frame.origin.y == theView.frame.origin.y) && (selectedView.frame.size.height == theView.frame.size.height))

仅适用于等y原点和高度的视图。我将使用以下伪代码解决此问题：

initialize an empty arranged subviews array
initialize a nil previous subview
for every subview
    if the subview intersects with the previous subview
        ensure the subview and the previous subview are added to the arranged subviews array
    else if the arranged subviews array is not empty
        arrange the subviews in the array across the width of their superview
        empty the arranged subview array

确定，

然而，我接受了SaltyMule的方法，他的伪代码在if / else中没有意义。
