init

问题 On my Fedora Core 9 webserver with kernel 2.6.18, init isn't reaping zombie processes. This would be bearable if it wasn't for the process table eventually reaching an upper limit where no new processes can be allocated. Sample output of ps -el | grep 'Z' : F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME CMD 5 Z 0 2648 1 0 75 0 - 0 exit ? 00:00:00 sendmail <defunct> 1 Z 51 2656 1 0 75 0 - 0 exit ? 00:00:00 sendmail <defunct> 1 Z 0 2670 1 0 75 0 - 0 exit ? 00:00:02 crond <defunct> 4 Z 0 2874

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: initWithNibName VS viewDidLoad I'm new at iOS development. I would just like to know the main differences between these 2 functions ? Thanks for your help 回答1: viewDidLoad Is called when the view loads and is initiated/Unarchived and loaded into the memory. This is a great customisation stop. initWithNibName: Is used for initializing a certain class ( it is an overriden init method) with a xib file's name, the

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . I don't understand what these are used for, particularly the self argument? Could some please explain this to me and why on earth you would want to pass this in? Also, I've always thought __init__ was for 'initialisation', but it didn't occur to me that I've never had to put

问题 I have been working on a new installation of a Zend Framework application for a while now, and I cannot figure out what's going on. I have two custom action helpers I would like to use and I would like to initialize those in the bootstrap. But it seems as though my _init functions are not being called at all. In the index.php that starts the application I have: require('Zend/Application.php'); $app = new Zend_Application(APPLICATION_ENV, APPLICATION_PATH .'/configs/application.ini'); $app-

问题 If I have an NSObject subclass which either has no -init method or simply does nothing in -init , is there any difference between an instance created these two ways: MyClass *instance = [MyClass alloc]; MyClass *instance = [[MyClass alloc] init]; By "does nothing in -init " I mean - (id)init { self = [super init]; if (self) { } return self; } Since NSObject 's -init method itself does nothing, I can't see there being any difference, but of course the advice is that you must call -init to

问题 This is a follow up to my other post Installing signal handler with Python. In short, Linux blocks all signals to PID 1 (including SIGKILL) unless Init has installed a signal handler for a particular signal; as to prevent kernel panic if someone were to send a termination signal to PID1. The issue I've been having, is it would seem that the signal module in Python doesn't install signal handlers in a way the system recognises. My Python Init script was seemingly, completely ignoring all

问题 I have a class Message with two attributes, name and message , and another class MessageController with two text fields, nameField and messageField . I want to make an instance of Message in MessageController , passing these two attributes as arguments. Right now, I am doing this: Message *messageIns = [[Message alloc] init]; messageIns.name = nameField; messageIns.message = MessageField; How can I pass the values at the creation of an instance? I tried to redefine init in Message.m, but I

问题 I am trying to use python logging with a config file and an own handler. This works to some degree. What really puzzle me is __init__ being called twice and __del__ being called once. When I remove the whole config file stuff and create the handler directly within the code __init__ is called once and __del__ is never called. My questions: Why is __init__ called twice? Why is __del__ called less often than __init__ ? The code: #!/bin/env python import logging import logging.handlers import

问题 Is it possible, if yes how, to have multiple init without parameter, in a Class like this (the string is just an exemple): aVar: String init() { aVar = "simple init" } initWithAGoodVar() { aVar = "Good Var!" } initWithFooBar() { aVar = "Foo Bar" } 回答1: You cannot have multiple init s without parameters since it would be ambiguous which init method you wanted to use. As an alternative you could either pass the initial values to the init method. Taking the example from your question: class

问题 I am wondering what is the cleanest way to initialize a custom UIView with a specific frame. The UIView is designed from a XIB file. Here is my implementation : class CustomView : UIView { @IBOutlet var outletLabel: UILabel! public required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) setupView() } public override init(frame: CGRect) { super.init(frame: frame) setupView() } private func setupView() { // Set text for labels } } Here is how I want to initialize it in my
