Uitableview is a control with high usage during iOS development. For me, almost every view I make has its own figure. But for a long time, I had a superficial understanding of her. Two things that touched me a lot. One is the custom uitableviewcell mentioned above, and the other is the reuse that we will mention today.The so-called reuse of the surface meaning to understand is reuse.

Often used in the development of the iphone application process should be regarded as uitableview, with iOS to UITableView endowed with this flexible framework structure, let it in the display list or in the layout has a certain advantage. Although UITableView is powerful, there are some problems in the development process for some complex application requirements, such as dynamically changing the cell height of the UITableView display is one of themA
This is often the case when using Table view: The contents of the cell in the table view are dynamic, resulting in a cell's height being not known at the time of development, so it is necessary to provide an algorithm for calculating the cell height, each time it is loaded into this cell Calculate the true height of the cell.Prior to IOS 8Without using AutoLayout
UITableViewCell Height Calculation rowheightUITableViewWe are familiar with the view, its delegate and data source callback do not know how many times, but also encountered the UITableViewCell height calculation. UITableView queries the cell height in two ways.One is for cases where all cells have a fixed height, by: 1 Self. 88; The above code specifies that all cells are 88-height uitableview, and it is strongly recom

In J2EE-based information systems, Java Applet with rich performance is an important form of interface layer. However, Java APIs have poor support for printing, and printing and outputting complex documents and reports requires a lot of work. The system described in this article solves this problem by introducing an ActiveX control-Cell plug-in. In this system, the interface is displayed by a Java Applet and printed and output by the
