A package can be directly understood as a namespace, a folder, which is used to organize the encapsulation of graphics. A package chart can be used to express the organizational layers of the namespace of a function group. Dynamic View

For example, the projection of the principle of interpretation, can be animated flash form the visual image of the entire projection process, so that students have a vision of the projection theory, for the three-view restoration of space-based content, teachers can use the computer in advance to make three-dimensional map, when the students can not come out, the three-dimensional graphic display to students.

BodyThe headline is a bit scary, but drawRect the evaluation is not too much. In the development of weekdays, the random coverage drawRect method, a little careless will make your program memory burst. Let's look at an example below.Do an artboard function, but suffer from memory problems have not been solved. The artboard function is simple, which is to record the track of your finger touch and then draw it on the screen. Let's take a look at the following:We see the state of the left memory de

It is a "virtual table" with only definitions but no data ". when creating a view, you only save the definition information of the view in the data dictionary. instead of copying the actual data to any place, you do not need to allocate storage space for the view in the tablespace.

When the activity receives the focus, it will request to describe its layout. The android framework will deal with this plotting process, but the activity must provide its layout hierarchy and nodes. It starts from the root node of the layout. It must measure and describe the layout tree. Plotting is done by traversing the entire layout tree, and each view object that is intersecting with the invalid area is displayed during the traversal process. Each viewgroup is responsible for requesting eac

Label:What is a view? ）1. A view is a database object, a virtual table that is exported from one or more data tables or views, and the data corresponding to the view is not really stored in the view, but is stored in the referenced data table, and the structure and data of the view are the results of querying the data table. 2. Depending on the criteria given when creating the view, the view can be part of a data table or a union of multiple base tabl

Drawing PeriodThe description system invokes the DrawRect: Method of the UIView object and passes it a rectangle containing the view area that needs to be redrawn. There are several actions to trigger a view update:Move or delete other views that obscure your view.Sets the hidden property declaration of the view to no so that it becomes visible from the hidden state.Roll the view out of the screen, and the

In iOS, windows and views are used to applyProgramIs displayed on the screen. Windows itself does not have visible content, but it provides a basic container for the application's views.

maintenance points. At the same time, if you try to describe the system through a large image, you will find that adding or even adding an element to the view will be an "impossible task". You will need to find free space to draw new elements and avoid cross-link connections. In the end, you can create a very complex graph. This graph is hard to understand, not really useful and almost impossible to print on a piece of paper.Modeling tools can better support such complex modeling tasks than
