refactoring. The following is a list of modified content: 1. Check whether the value of nextProjectile is nil at the beginning of the function. This means that our current touch event is happening in the shooting process. That is to say, the turret has shot a bullet. 2. Previously, we used a projectile local variable and added it to the current scenario. In this version, we added a member variable of nextProjectile, but it was not immediately added to the current scenario. Because it will be us

IOS development-Stage 3-Weibo (7) (Program 4) and ios Stage 3 Encapsulate the information displayed on the Cell into two model classes: The difference between the plus sign and the minus sign is very simple. In short, the difference is:The plus sign can directly call this method through the class name, while the minus sign will instantiate an object and the

C Language Enhancement (7) linked list intersection question _ 3 determine whether a linked list has a ring and intersection _ 3 The premise of the previous two discussions is that the linked list has no loops, but what if the linked list has loops? Obviously, if the linked list has a ring, the function of searching for the End Node of the linked list will be in

have seen, remember that vivid animated short film Big Buck Bunny? The interesting film shows the application of smooth streaming technology in Silverlight 3. So, what exactly is smooth streaming technology? A good explanation is that Smooth streaming is an extension of IIS Media Services, which enables Silverlight clients to adapt to streaming bandwidth via HTTP, and through special handling of video source files such as WMV, commonly used video fil

Raspberry Pi 3 already supports Bluetooth and built-in wireless NICs by default. The price is only $35. I was lucky enough to have a copy of X Package. I also used Raspberry Pi for the first time. Because Raspberry Pi 3 was just launched soon, there are few tutorials on the internet. Let's share with you how Raspberry Pi 3 installed centos

Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to run/bin/sh, and if it fails, the boot of the system will fail.Linux 7 RunLevel (0: shutdown, shutdown mode,1: single-user mode,2: Multi-

1. Windows Phone 7 is a multitasking operating system, but allows only one third-party application to run in the foreground 2. Initiators and selectors provide an indirect way for applications to access the built-in functionality of the phone. Some built-in initiators: Emailcomposetask, Marketplacedetailtask, Marketplacehubtask, Marketplacereviewtask, MarketplaceSearchTask , Mediaplayerlauncher, Phonecalltask, Searchtask, Smscomp

CentOS 7 has a built-in Python version of 2.x, and many programs rely on the 2.x version, which will invalidate some of the Python scripts.For example: Yum, Firewall-cmd, Firewall-config, and so on.If you encounter a similar reference error, this is basically the cause: [Email protected] bin]# Firewall-configTraceback (most recent):File "/usr/bin/firewall-config", line, in Import GIModulenotfounderror:no module named ' GI ' A python reference

One, object-oriented characteristics Three basic features: encapsulation, inheritance, and polymorphism. 1, packagingThe core idea of object-oriented programming this is to encapsulate the data with the operations of the data. By abstraction, that is, extracting common properties from concrete instances to form general concepts, such as class concepts. 2. InheritInheritance embodies an advanced programming pattern. Subclasses can inherit the properties and functionality of the parent class, whic
