This article mainly introduces the _ init _ () method in Python, __init _ () is an important basic knowledge in Python learning, for more information, see _ init. The first reason is that initialization is the most important step in the object lifecycle; each object must be correctly initialized before it can work normally. The second reason is that the _ init _

We call the class method to receive and process a color, finally return a value of the string type, and then use a string variable to receive the value, and then output this value, this is the whole ideaNSString *str=[iphone TOGETIPHONECOLOR:KCOLORTHJ];NSLog (@ "%@", str);}return 0;} ———————————————————————————————————————————The concept and use of anonymous classes #import #import "Car.h"int main (int argc, const char * argv[]) {@autoreleasepool {① use anonymous classes to i
The recommended init Method for objective-C is written as follows:
-(ID) Init {If (Self = [Super init]) {// Add attributes to the subclass for initialization} return self ;}
The return value is of the ID type. The ID type can be assigned to other types of pointers. Other types of pointers can also be assigned to the ID type.
In OBC, subclass pointers cannot be d
condition occurs, the action is added to the end of the execution queue unless it is already in the queue.
Each action in the queue is extracted in sequence, and each command in the action is executed in sequence. During the execution of these commands, init also controls other activities (device node creation and cancellation, attribute setting, and process restart ).
The form of actions is as follows:

Difference between initialize, init, and load methods and when to call initializeinit
Initialize is not init
When initialize is called for the first time, for example, [[class alloc] init] will call the initialize method once. No matter how many times this class is created, it will only call this method once, we use it to initialize static variables. The
Linux initrd (linuxrc, init)
From Linux Oracle Baidu Space
Linux's initrd technology is a very common mechanism. The file format of initrd in the Linux kernel is changed from the original file system image file to the cpio format, and the changes are not only reflected in the file format, the Linux kernel processes initrd in these two formats differently. This article first introduces what is initrd technology, and then introduces the initrd proc
This article describes the differences between _ init _ and _ new _ in Python, it also highlights the role of _ new _ and when _ new __is used. For more information, see

1.Initwithcoder This function is called when a view is initialized from the nib. Use Keyedarchiver to serialize the strength of a class, which is then called back with Keyedunarchiver2.initialize This is still the first time these days, and the usual use of the init is different. Initialize I understand as passive invocation. Scenario: When writing a class where all the methods are class methods (+), if you need to have global variables, where should

public static function init(){ /** 设置自动载入函数 */ if (function_exists('spl_autoload_register')) { spl_autoload_register(array('Typecho_Common', '__autoLoad')); } else { function __autoLoad($className) { Typecho_Common::__autoLoad($className); } }}
What does the static method above mean, define a function, but not invoke it to execute? I can't read and answer.

Recently I wrote a Weibo client using Android-universal-image-loader.
InProgramBefore development, I do not know that there is such a good thing as Android-universal-image-loader. In fact, it is very convenient to use it. You can refer to the demo for details.
Android-universal-image-loader encountered some problems during use. At that time, it was built based on the official demo, but the program was never running. The following error will be reported:
