代码：
var attachmentListCollectionView:UICollectionView func reloadDataAndUpdateFrame() { gLog.verbose("self.curItemList.count=\(self.curItemList.count)") self.attachmentListCollectionView.frame = CGRectMake( 0, 0, AttachmentTableViewCellWidth, calcAttachmentViewHeight(self.curItemList.count)) let orginContentFrmae = self.contentView.frame self.contentView.frame = CGRectMake( orginContentFrmae.origin.x, orginContentFrmae.origin.y, orginContentFrmae.width, self.attachmentListCollectionView.frame.height) gLog.verbose("orginContentFrmae=\(orginContentFrmae) -> self.contentView.frame=\(self.contentView.frame)") //orginContentFrmae=(0.0, 0.0, 320.0, 71.5) -> self.contentView.frame=(0.0, 0.0, 320.0, 72.0) //orginContentFrmae=(0.0, 0.0, 320.0, 71.5) -> self.contentView.frame=(0.0, 0.0, 320.0, 144.0) let orginSelfFrmae = self.frame self.frame = CGRectMake( orginSelfFrmae.origin.x, orginSelfFrmae.origin.y, orginSelfFrmae.width, self.attachmentListCollectionView.frame.height) gLog.verbose("orginSelfFrmae=\(orginSelfFrmae) -> self.frame=\(self.frame)") //orginSelfFrmae=(0.0, 476.0, 320.0, 72.0) -> self.frame=(0.0, 476.0, 320.0, 72.0) //orginSelfFrmae=(0.0, 476.0, 320.0, 72.0) -> self.frame=(0.0, 476.0, 320.0, 72.0) //orginSelfFrmae=(0.0, 476.0, 320.0, 72.0) -> self.frame=(0.0, 476.0, 320.0, 144.0) self.attachmentListCollectionView.reloadData() } |
还是没有效果：
－》
字页面中高度，还是没有反应到父页面中。。。
ios – Autoresize UICollectionView height to adjust to its content size – Stack Overflow
xcode – Resize UICollectionView Height – Stack Overflow
ios – UICollectionView autosize height – Stack Overflow
uicollectionview change frame size
最后的最后，还是强制更新了整个父页面的TableView后，才使得UICollectionView的父页面中的cell的高度正常：
相关部分的代码：
