Tips and skills for Xcode Development

XcodeDevelopment tips andTipsIs the content to be introduced in this article, I always try to remember a varietyXcodeAs well as various prompts andTips. During programming, I always try to use the mouse as little as possible. Without these prompts, I will be at a loss. Here we record these prompts andTipsThe best place. This is the first article. I hope there will be moreXcodeAndTipsArticle.

Vertical Split editor View

If you prefer to use multiple code windows at the same time, the editor split option can help you pay attention to small and medium-sized square grid icons ).

By default, windows are horizontally split. If you want to observe your code in parallel for comparison), the following describes how to vertically split the window:

Press the Option key when you split the window icon.

You can add annotations for a piece of code as follows:

Select one or more lines of code to be annotated

Press Command -/

To remove the annotation of a piece of code, repeat the above steps.

Key and action ing Key Binding)

The above prompt can indeed save a lot of time. However, I found that I prefer to map actions to buttons as usual. For example, I can map the action in the previous prompt to Option-S, just like most switching and switching actions.

1. Select Prefereces preference from the Xcode menu)

2. select Key Bindings to bind)

Option-Command Right-Arrow move to the next file
 
 

Bookmarks

I can't imagine there is no way to do it during programming.BookmarksSet what will happen. When I want to continue to find a piece of code in another file, I often need to set bookmarks. Bookmarks are simple:

 
 

  
  
Control-D 
 
 

Enter the bookmarks

Jump to bookmarks

There are two ways to jump to bookmarks. First, you can select the bookmarks icon in the upper-right corner of the editor window.

You can use the following key to obtain the same menu:

Command-] Move code to the right
 
 

The above method works no matter where you are in the code line. In other words, you do not have to be at the beginning of a line.
