IOS development practices-cell download image (custom NSOperation) The image downloading operations in the previous article are all placed in blocks. When complicated operations are encountered, a bunch of code is put in blocks. Obviously, this is not a wise choice, and the code looks bloated. Therefore, place thread operations in custom NSOperation. Step for customizing NSOperation: Inherit NSOperation and override-(void) main method to implement the

In this article, let's talk about the cell adaptive height of uitableview and the solution to the problems encountered. Before reading the article, I hope you will have UITableView basic use.The GitHub address for the demo of this article first: Uitableviewcellheightdemo. You can download it and read the article together.History of cell height calculationsBefore iOS8, if the height of UITableViewCell is dyn

We often need to edit the table in WPS text. Sometimes, you need to enter more content in a cell, but you can not arbitrarily increase the column or row height of the cell, it is not appropriate to arbitrarily adjust the small size. I have encountered such a problem, when there is a "one millimeter baffled hero Han" feeling. I am not a hero Han, we can not let this one millimeter in vain to baffle us. After

Use coordinates of an image to generate a cell, similar to csssprite. The general idea is that each cell has two indexes that are data-driven. When creating an instance, arrange the instance in disorder in 0-9. Each cell corresponds to two indexes. One is the index of the actual location, and the other is the record... SyntaxHighlighter. all (); Use coordinates o

When I first started learning iOS, I asked the big gods what was the hardest part of iOS development. Some people say that custom controls, UI, and interaction design. At that time I was doubtful, with the development of their own in-depth, I really have experience. Development of an app product, a large part of the time is to deal with the UI. Because many of the features in the development are directly encapsulated or have ready-made templates to use, only the UI is changeable according to the

Recently using the Pea pod at a glance at the app when you see it's click cell after the pop-up interface animation is very handsome, so I figured out the realization of one, the effect is as follows:Careful observation of the effect is divided into several parts, click on the cell, the first background will appear shadow, only click on the cell is still lit, and

Last episode "CSS in-depth study: Display of the horror of the Story of decryption (1)-Display-inline" has pulled the list of properties of display to sneak out, found in this property horror is actually a fragile disguise. In addition to some of the commonly used properties, the others are legendary brother. Since it is legend brother, please do not infatuation. Let the legend continue to legend. This time we'll take care of the Table-cell. (TABLE-CE

The column order set in DataGridView is not index of the represented cell[]. The index of the cell corresponds to the column index in the data source.For example: Select unique number, resume number, field number, status, field name, SQL, sequence number from table sothe column corresponding to the cell in the DataGridView iscell[0]: unique number

The last shared custom cell was optimized: http://blog.csdn.net/qq_31810357/article/details/49611255To specify the root view: Self.window.rootViewController = [[Uinavigationcontroller alloc] initwithrootviewcontroller:[[ Roottableviewcontroller alloc] Initwithstyle:uitableviewstyleplain];Roottableviewcontroller.m#import "WGModel.h" #import "WGCell.h" @interface Roottableviewcontroller () @property (nonatomic, Strong) Nsmutabledictionary *datadict;

align elements on both sidesThe first case is to align the two elements to the left and right, and if it is in the past, I will definitely use float to do so, but in fact it can be done with table:* { box-sizing:border-box;}. Content { display:table; border:1px solid #06c; padding:15px 5px; max-width:1000px; margin:10px Auto; min-width:320px; width:100%;}. box { width:100px; height:100px; border:1px solid #ccc; Text-align:center; Display:inline-block; fo

Cell editor requirements Recently, I need to develop a small application by myself and use SWT to design the interface. In this case, I need to use JFace TableViewer. After using TableViewer, I found that it is easier to use than Swing JTable, in addition, it is more convenient and easy to add an editor to the cells in the table (it may also be the illusion that I have not studied the cell editor in Swing's

Next, let's take a look at the simple use of Table View in iOS. Here we will focus on Cell operations in UITableView, including tag, move, delete, and insert. For the sake of simplicity, directly from the original code, code: http://download.csdn.net/detail/totogo2010/4361870 To perform data operations, change the immutable array in the code to variable: NSArray * list-> NSMutableArray * list1.
