From 56542ae8cf57d5f8cbb9802bc52ca62a91b6f043 Mon Sep 17 00:00:00 2001 From: ctaodream Date: Sun, 24 Aug 2014 02:34:04 +0800 Subject: [PATCH] leave one cell in quiltView MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit sometimes ,there is only one cell in quiltView ,at this time,*top == *bottom,if we remove the only cell ,then we can not see any cell. I often use class with "top view" or "bottom view", yeah! for example ,I set the margin top 300dp,and I add a TopView in the quiltView ,the TopView like the head of UITableView, but When I drag it down until the first cell disappear in quiltView ,I loosen. I am so puzzled that I can only see the TopView , the cell disappear,but when I swipe the quiltView fastly ,sometimes all cells has appear.Although like this，I think the quiltView still has one flaw，so I restore it . --- TMQuiltView/TMQuiltView/TMQuiltView.m | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/TMQuiltView/TMQuiltView/TMQuiltView.m b/TMQuiltView/TMQuiltView/TMQuiltView.m index abad306..a887121 100644 --- a/TMQuiltView/TMQuiltView/TMQuiltView.m +++ b/TMQuiltView/TMQuiltView/TMQuiltView.m @@ -466,7 +466,9 @@ - (void)layoutSubviews { // Harvest any any views that have moved off screen and add them to the reuse pool for (NSIndexPath* indexPath in [indexPathToView allKeys]) { TMQuiltViewCell *view = [indexPathToView objectForKey:indexPath]; - if (![TMQuiltView isRect:view.frame partiallyInScrollView:self]) { // Rect intersection? + // the indexPathToView must has one indexPath，we should not remove all cell in quiltView, + // if *top == *bottom ,there is one cell in quitView ,so at this time,cell can not be removed + if (![TMQuiltView isRect:view.frame partiallyInScrollView:self] && indexPathToView.count > 1) { // Rect intersection?
