In iPhone development, we often need to perform animation switching between different pages, which looks better. There are three basic animations:
1. uiview
Uiview provides five official animation effects for you:
Uiviewanimationtransitionnone does not use the animation rotate from left to right to flip pages. The opposite is uiviewanimationtransitioncurlup, and uiviewanimationtransitioncurldown.
Example:

Java list is just a container interface. Defining a list must be implemented using some implementation classes such as arraylist.
Several key points for using list:
① The add () method of list can only add objects and cannot add basic data
List data types and common operations of python, and list data types of python
A list is the most common Python data type. It can appear as a comma-separated value in square brackets.
Each element in the list is assigned a number-
for choosing the data format:
· If the space is not a problem, use linear PCM to encode each audio. This not only enables you to play audio as quickly as possible, but also enables you to play multiple sounds simultaneously without occupying CPU resources.
· If space is a problem, most of the time you use AAC to encode your background music and ima4 to encode your sound effects.
Many variants of linear PCM
Another important issue about linear PCM needs to be emphasized, that is, this uncompress

There are two main ways to achieve beautiful iPhone animation effects: one is at the uiview level, and the other is to use catransition for lower-level control,The first is uiview. The uiview method may also be encapsulated by catransition on the lower layer. It can only be used for some simple and common effects. Here, we will write a common sample code, for your reference.

Last week the code encountered a problem, because of design constraints, a method accepts parameters only listEnumerable.oftypeThis method is implemented by using deferred execution. The immediate return value is an object that stores all the information that is required to perform the operation. The query represented by this method is executed only when the object is enumerated by invoking the GetEnumerator method of the object directly or by using foreach in Visual C # (or for each in visual B
