as a wireframe editor and contains a large number of wireframe parts. We can use this to create wireframe for our own websites and applications. It is designed for iOS and Android applications and features storyboards, which means we can combine storyboards with wireframe to complete the scene design. All in all, if you want to make your interface design more convincing, then visual paradigm is an option.Ten. Dub–denimThis model tool has the advantage of paper sketching and also provides modern

Some of the pages in the project, I used the HTML page development, and then loaded the design with Wkwebview. In the loading process encountered some problems, here are some records and discussion. If you have a different opinion, please feel free to comment. The problem is this: it can't be loaded in WebView's loadrequest.webview.m中的代码：//self.PageUrlString:加载的链接地址 if (self.PageUrlString) { [self.wekView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:self.PageUrlString]]]

, waste space, but the destruction of two times there is a problem. Because the same object is manipulated at the time of the destruction. So assuming that the object has allocated memory internally, it will cause double free for this memory because the pointer is the same.

Linux Shell and commandsThere are many commands for Linux, and a simple classification is given below.It is shell programming to organize the Linux commands in the shell to complete a series of tasks. Shell,perl and Python are the most common scripting languages on Linux, and I recommend using Python.Linux applicationsStandard Linux systems generally have a set of assemblies called applications, includin

Nano shortcuts available are shown below the user interface, and the Nano has only the functionality of the most basic text editing software. It is very compact and is ideal for editing system configuration files. For those who do not need complex command-line editing capabilities, the Nano is perfectly equipped.What do you think?Here are some other editors I'd like to mention: the Nice editor (NE): The official website says: "If you have enough information, you have the patience of using Emacs

and commandsThe shell is the user interface of the system and provides an interface for users to interoperate with the kernel. It receives the command entered by the user and sends it to the kernel to execute, which is a command interpreter. There are many types of shells, and bash is recommended here. Bash is the GNU Bourne Again Shell, the default shell on the GNU operating system, and most Linux distribution kits use this shell.There are many commands for Linux, and a simple classification i
