MATLAB search cell array for string subset

試著忘記壹切 提交于 2019-12-10 14:24:52
问题 I'm trying to find the locations where a substring occurs in a cell array in MATLAB. The code below works, but is rather ugly. It seems to me there should be an easier solution. cellArray = [{'these'} 'are' 'some' 'nicewords' 'and' 'some' 'morewords']; wordPlaces = cellfun(@length,strfind(cellArray,'words')); wordPlaces = find(wordPlaces); % Word places is the locations. cellArray(wordPlaces); This is similar to, but not the same as this and this. 回答1: The thing to do is to encapsulate this

ios8 UITableView scrollToRowAtIndexPath inaccurate with auto sizing cells

假如想象 提交于 2019-12-10 14:12:56
问题 When I try to scroll all the way to the bottom of a table view when my view first appears, it doesn't scroll to the correct bottom cell. It's somewhere close to the end but not quite. If the method is called again later, it then scrolls to the bottom. For now my solution was to scroll twice, and it only works if there's a delay on the second one. I'm wondering if this is a bug in iOS 8 or if there's anything I can actually do the proper way. NSIndexPath* path = [NSIndexPath indexPathForRow:

Why is Cell.CellReference optional? How do I get cell location otherwise?

爷,独闯天下 提交于 2019-12-10 14:05:51
问题 According to the OpenXml spec CellReference is optional. But is there an alternative way to get a cell's location? For example, I can get a row's cells by something like: foreach (Row r in sheetData.Elements<Row>()) { foreach (Cell c in r.Elements<Cell>()) { Console.WriteLine(c.CellReference); } } But without CellReference, how do I know the cells' locations? I have done some research and all solutions seem to rely on comparing a cell's CellReference against a given string. 回答1: The

Keep selected cell on heavily reloadRowsAtIndexPaths UITableView

问题 In one of the views there is a UITableView which is getting updated rather often. Tracking the changes are done in a classic way using "reloadRowsAtIndexPaths" -(void)refreshCells:(NSArray *)changedCells { NSLog(@"refreshCells %i",[changedCells count]); [TableView beginUpdates]; [TableView reloadRowsAtIndexPaths:changedCells withRowAnimation:UITableViewRowAnimationBottom]; [TableView endUpdates]; } Question: How can I preserve the user's last selected Cell. the cell position may change after

iOS核心动画高级技巧 - 7

13. 高效绘图 高效绘图 不必要的效率考虑往往是性能问题的万恶之源。 ——William Allan Wulf 在第12章『速度的曲率』我们学习如何用Instruments来诊断Core Animation性能问题。在构建一个iOS app的时候会遇到很多潜在的性能陷阱,但是在本章我们将着眼于有关绘制的性能问题。 13.1 软件绘图 软件绘图 术语绘图通常在Core Animation的上下文中指代软件绘图(意即:不由GPU协助的绘图)。在iOS中,软件绘图通常是由Core Graphics框架完成来完成。但是,在一些必要的情况下,相比Core Animation和OpenGL,Core Graphics要慢了不少。 软件绘图不仅效率低,还会消耗可观的内存。 CALayer 只需要一些与自己相关的内存:只有它的寄宿图会消耗一定的内存空间。即使直接赋给 contents 属性一张图片,也不需要增加额外的照片存储大小。如果相同的一张图片被多个图层作为 contents 属性,那么他们将会共用同一块内存,而不是复制内存块。 一个开发者,有一个学习的氛围跟一个交流圈子特别重要,这是一个我的iOS交流群:1012951431, 分享BAT,阿里面试题、面试经验,讨论技术, 大家一起交流学习成长!希望帮助开发者少走弯路。 但是一旦你实现了 CALayerDelegate 协议中的

动态布局UITableView的cell , header , footer

生来就可爱ヽ(ⅴ<●) 提交于 2019-12-10 11:57:14
对于固定显示的 直接添加个一个view 上就行, 类似上面的 开单办卡, 用一个bgView 添加这两个控件 需求 : 上面的 view 是 UITableview 的 头部, 不是分区的头部, 有卡显示卡模块, 没卡, 就不显示 此时最好的解决方法, 就是 卡的背景view换成UIScrollView 。 然后给它 添加一个高度约束, 因为 UIScrollView 有contentSize 改变约束, 内部 不会出现UIView 一样的 设置高度0 但是子控件还会撑满的情况 代码 /// 卡view的高度 private var svHeightCon:NSLayoutConstraint? /// 卡view private func configCardBgSV() -> UIScrollView{ let cardBgSV = JYUIModel.createScrollView(showVScrollIndicator: false, showHScrollIndicator: false, bounces: false) self.svHeightCon = cardBgSV.heightAnchor.constraint(equalToConstant: 56) self.svHeightCon?.isActive = true return cardBgSV }

iOS 8 Self Sizing Cells - Allow Zero Height

寵の児 提交于 2019-12-10 11:54:31
问题 I am using the self sizing cell feature and it works well until I want to hide a cell completely. I moved away from heightForRowAtIndexPath for this and I setup the following: override func viewDidLoad() { self.tableView.rowHeight = UITableViewAutomaticDimension self.tableView.estimatedRowHeight = 0 } However when I have no text for a tableviewcell to render I get the following message: Warning once only: Detected a case where constraints ambiguously suggest a height of zero for a tableview

Change a Value of the columnModel JQgrid after draw

好久不见. 提交于 2019-12-10 11:54:00
问题 when i draw the grid i have some column like this.. name: 'codigo', index: 'codigo', width: 50, align: 'center', editable: true } But after i want to do a query and then set the editable option, for example to false, is this possible? Thanks. 回答1: You can get reference to internal colModel using getGridParam : var colModel = $("#grid").jqGrid("getGridParam", "colModel"); Now you can enumerate elements in colModel array and find the element which has property name with the value "codigo" .

Find Last cell from Range VBA

问题 How to find location of last cell from defined Range? Cell does not have to contain any data but must be most right and most down located cell from certain Range. Set rngOrigin = wksOrigin.Cells(IntFirstRow, IntFirstColumn).CurrentRegion I wish to receive Cells(i,j) 回答1: Perhaps this is what you want: Dim rngLastCell As Range Set rngLastCell = rngOrigin(rngOrigin.Count) 回答2: try the following rngOrigin.End(xlDown).End(xlRight) or you could use the CurrentRegion and count the rows and columns
