能不能 用一个 int 类型的 构造 NSIndexPath？

Question

我看了一下 NSIndexPath 的构造方法 应该可以
于是我尝试
videoArray.removeAtIndex(index)
var indexPath = NSIndexPath(index: index) self.collectionView?.deleteItemsAtIndexPaths([indexPath])

但是 最后一行的时候 会报错

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of sections. The number of sections contained in the collection view after the update (1) must be equal to the number of sections contained in the collection view before the update (1), plus or minus the number of sections inserted or deleted

我觉得应该是构造的不对

Answer 1

var index: NSIndexPath = NSIndexPath(forRow: 1, inSection: 1) 这样可以 我弄错了
