Today, I saw the shortcut point of running a project and the shortcut key of creating a project

Recompile the Xcode project

command + R
Copy the code

2. Create a shortcut key for the project

shift+command+N
Copy the code

Note that on the MAC desktop, using this key is to quickly create folders for me to remember

3. Move the cursor quickly to the beginning and end of a file

command+up 

command+down
Copy the code

We know that in Vim /vi the shortcut for the cursor to the beginning and the last line of the file is

gg

shift + G
Copy the code

4, move the cursor to the front/back of the line:

Command + left/rightCopy the code

5. Quickly switch to.m /.h files:

command + control + up/down
Copy the code

6. Fast to the line of text

command + L
Copy the code
