UITableView 系列之自定义 UITableViewCell

左心房为你撑大大i 提交于 2019-11-28 14:58:12
本来不打算写UITableView的,因为网上已经有很多这方面的文章,尤其是 趣味苹果开发中的TableViewController系列 已经有很详细的讲解了。但是群里还是有很多童鞋会问这方面的问题,所以在这里以自己的理解方式比划一下。 让我们先来看一张从模拟器截下来的图: 上图是一个UITableView列表,红色的1、2、3、4、5...是一个个的UITableViewCell。 从这张截图我们可以看出来 UITableView 是由一系列 UITableViewCell 组成的列表,由此我们可以知道 UITableViewCell 在 UITableVeiw 中的重要性了。 在真实地项目中,UITableViewCell 中的各项内容的排列都不同(如上图4中的 2013年、全国等),它自带的那几种样式根本无法满足我们的需求,所以这就需要我们来自定义自己的Cell(下文中的Cell都表示UITableViewCell)了。 以上图中的Cell为例,我们来自定义一个UITableViewCell。首先我们来创建一个应用——CustomTableVeiwCellDemo, 打开XCode,选择File -> New -> Project...,如下图所示: 然后选择iOS->Application->Single View Application,然后点Next,如下图所示:

Grouping matrix rows in terms of one column

别来无恙 提交于 2019-11-28 13:59:39
First of all it is really hard for me to describe the problem really good but I'll try. Say that we have matrix A A = [23 1; 45 1 78 1 86 1 98 2 1 2 23 2 14 3 15 4 85 4] What I want as an output is B{1} = [23,45,78,86] B{2} = [98,1,23] B{3} = [14] B{4} = [15,85] Bear in mind that the original A is a huge matrix, and I do not wanna do this with for loops. I would like to use functions that uses parallel processing. You could use accumarray here: B = accumarray(A(:,2),A(:,1),[],@(x){x},{}); If you know that A is sorted, and that there is no missing entry from the second column, you can also use

what are “virtualized controls” ? (mentioned in JavaFX documentation).

眉间皱痕 提交于 2019-11-28 13:51:26
from http://docs.oracle.com/javafx/2/api/javafx/scene/control/Cell.html : "The Cell API is used for virtualized controls such as ListView, TreeView, and TableView. A Cell is a Labeled Control, and is used to render a single "row" inside a ListView, TreeView or TableView." Why are they virtualized? When you have a lot of data to display in a Control such as a ListView , you need some way of virtualizing the Nodes created and used. Otherwise it will affect the memory footprint and consequently the time. For example, if you have 10 million data items, you don’t want to create 10 million Nodes. So

Highlighting adjacent cell ten business days (exclude holidays) after the date found in the cell beside it

偶尔善良 提交于 2019-11-28 11:38:55
问题 I have been trying to work on this with conditional formatting for a couple of days now to no avail I have made it so that every time a "FILE NUMBER" is entered the cell to the right in grey shows the date it was entered in dd-Mmm-yy (ex. file number is C8 date is entered in D8). Now what I need is a macro or conditional formatting that will highlight the "Motion" (B, E...) and "FILE NUMBER" (C, F...) cells in red when 10 ***business/work days have passed from the initial date entered in the

i'm currently developing on an app, which displays some tweets in a tableview. On the storyboard i created a prototype-cell, which includes the basic gui concept of a tweet entry. It looks circa like this: ++++++++++++++ ++Username++++ ++++++++++++++ ++Tweet+++++++ ++++++++++++++ ++Time-Ago++++ ++++++++++++++ Now i'm calculating the height of the cell with the following code, but somehow it fails. - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { NSDictionary * currentTweet = [tweetArray objectAtIndex: indexPath.row]; NSString * tweetTextString =

Floorplan : 要做好floorplan需要掌握哪些知识跟技能? 通常,遇到floorplan问题,大致的debug步骤跟方法有哪些? 如何衡量floorplan的QA? Floorplan基本上是后端硅农最花时间的部分,一般是在解决三个问题: IP、MEM、I/Opin、PAD/BUMP规划:琐碎重复且龟毛,可能就是在讲一个后端工程师在摆floorplan,经常的经历就是试过9527个FP后最后才发现第一个结果最佳。一般跟前端要一份data flow再去搞FP是明智选择,当然同时有前端详解各个不同模块的之间的联系和时序约束那是更棒。IP/IO的文档内一般会有一些place&route的建议,比如PLL周边的是否需要place halo/Litho,端口接线层次要求、方式(是否直连不可交叉),不可与哪些device临近摆放。 各种physical cell的放置:WELLTAP、ENDCAP、DECAP、PowerSwitch这些玩意儿在前端的世界里不代表什么,而跑到后端的世界里属于稍有闪失便会DRCfail 甚至打回重来的窘迫境地。熟读FAB提供的DRC file必要至极,各种基于DRC、DFM、甚至是后期PV tool run time的考量都会收录其中。 Power plan:想要chip跑的快,供电不足怎么行,FP里占比重较大的一部分就是Power plan

jqGrid Cell Editing - Double Click to Edit?

蓝咒 提交于 2019-11-28 10:26:17
By default, if a jqGrid cell is editable, single click on that cell changes it to edit mode. Is there any way I can make it edit on a double click instead? It would make it easier to do row-level operations such as deleting, as all the columns in my grid are editable. Yes, you can use the ondblClickRow event to capture a double-click. Here is a simple example to get you started: ondblClickRow: function(){ var row_id = $("#grid").getGridParam('selrow'); jQuery('#grid').editRow(row_id, true); } I got the answer. You only need to place the code on the jqgrid properties For example: width: 800,
