尝试用Carthage安装：
github "brightec/CustomCollectionViewLayout"
结果出错：
licrifandeMacBook-Pro:SalesAppiOS crifan$ carthage update CustomCollectionViewLayout –platform iOS *** Cloning CustomCollectionViewLayout No tagged versions found for github "brightec/CustomCollectionViewLayout" |
直接下载和导入源码吧
最后用代码：

注：
其中对于原有的：
CustomCollectionViewLayout.swift
中有少许改动：
class CustomCollectionViewLayout: UICollectionViewLayout { // let numberOfColumns = 8 var numberOfColumns = 8 |
然后后来为了允许自定义（CGSize类型的）itemSize：
let collectionViewLayout:CustomCollectionViewLayout = CustomCollectionViewLayout() collectionViewLayout.numberOfColumns = PotentialAnalysisColumnNumber let eachItemSize = CGSize(width: ScreenWidth/CGFloat(collectionViewLayout.numberOfColumns), height: 30) let itemSizeColumnList = Array<CGSize>(count: collectionViewLayout.numberOfColumns, repeatedValue: eachItemSize) gLog.verbose("eachItemSize=\(eachItemSize), itemSizeColumnList=\(itemSizeColumnList)") //eachItemSize=(64.0, 30.0), itemSizeColumnList=[(64.0, 30.0), (64.0, 30.0), (64.0, 30.0), (64.0, 30.0), (64.0, 30.0)] collectionViewLayout.itemsSize = itemSizeColumnList gLog.verbose("collectionViewLayout=\(collectionViewLayout)") //collectionViewLayout=<Sales_App.CustomCollectionViewLayout: 0x7b1a7ca0> self.collectionView = UICollectionView(frame: collectionViewFrame, collectionViewLayout: collectionViewLayout) |
然后把整个CustomCollectionViewLayout改动了不少，主要是语法上面的和个别变量全局化的：

UICollectionViewLayoutAttributes // let sectionAttributes = self.itemAttributes[indexPath.section] as! [UICollectionViewLayoutAttributes] let sectionAttributes = self.itemAttributes[indexPath.section] return sectionAttributes[indexPath.row] as UICollectionViewLayoutAttributes } override func layoutAttributesForElementsInRect(rect: CGRect) -> [UICollectionViewLayoutAttributes]? { var attributes = [UICollectionViewLayoutAttributes]() if self.itemAttributes != nil { for section in self.itemAttributes { // let filteredArray = section.filteredArrayUsingPredicate( // // NSPredicate(block: { (evaluatedObject, bindings) -> Bool in // return CGRectIntersectsRect(rect, evaluatedObject.frame) // }) // ) as!
