UITableView inherits from Uiscrollview, a scroll-based control that Apple encapsulates for us. The above is mainly a uitableviewcell, you can let UITableViewCell respond to a few click events, you can also add Uitextfield or Uitextview in the UITableViewCell, and other sub-views, Makes it possible to edit text on the cell.
The cell in the UITableView can have a lot of memory, typically by reusing the
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. The general working principle is: uitableview is lazy loading, that is, loading only the part that will be displa
TableView reuse mechanism, in order to achieve display and data separation, IOS TableView implementation and not for each data item to create a TableCell. Instead of creating a screen to display the largest number of cell, and then reuse these cell, the cell to do a separate display configuration, to achieve neither the effect of the display, but also the purpose

Different raster datasets do not need to be stored with the same cell resolution. However, when working with multiple datasets, it is best to use the same cell resolution. When you enter multiple raster datasets of different resolutions into any ArcGIS Spatial Analyst extension tool, one or more input datasets are automatically resampled to the most coarse resolution of the input dataset.By default, the nea

The first problem is that a uitextfield is placed on a cell in tableview, and the content of textfield is removed after the screen is displayed. Later, we knew that the cell was replaced (not released), and then re-built a textfield, which is not the previous one, so it must be empty. However, it is interesting to see that if you are editing a textfield and you draw it out on the screen, the
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

When the machine prompts that the power is low or the remaining power is insufficient, it can be charged.Tips for using cell phone battery:1. Do not overdischarge. When the device prompts "insufficient power", it should be charged. When the device is automatically shut down, it will be charged, and the battery has been o

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.
