General macro definitions and header files for the app development process

工欲善其事, its prerequisite.

Before you formally implement all the cool features and UI, getting ready is the only way to improve the efficiency of your next development.

So, this series, I am not in a variety of heap technology, more attention is "Bing" before the "grain line", some cumbersome, but when the whole context is clear, the follow-up work is only on the good Foundation and framework of unlimited expansion and optimization.

Macro definition is an effective tool for improving efficiency in the development process. It is necessary to summarize some globally common macro definitions for easy and efficient use.

As below, some general macro definitions should be developed as necessary:

The description is as follows:
1.[UIScreen mainscreen].bounds.size will change with the horizontal and vertical screen,[[UIScreen Mainscreen] currentmode].size will not change.

For example, the project general in the horizontal screen check, run on the iphone6s, the beginning of the vertical screen (375,667), the application rotated to the horizontal screen, the former width and height swapped (667,375); the latter is always (750,1334)

2.Deviceisiphone6plus Judge whether it is 6Plus, encountered some resolution is actually (1125, 2001) test machine, That is to say Bounds.size is (375,667), speculation is a refurbished machine

3.Deviceisipad When judging the ipad, there are more non-retina resolution ratios. Because debugging only iphone-type apps on ipad, you'll encounter this type of resolution

Macro definitions for the 4.ResizeSide and font series provide a simple reference scheme for width and font adaptation to multiple devices with code, and of course the masonry class library is the best solution for code adaptation devices, and is just for easy use

5.loadimage macro definition, uses the frequent IO way to load the picture resources, the purpose is avoids the memory cache to occupy for a long time. It is recommended that you add attributes or variable references when you need to preserve objects

6. If you are referencing a macro definition, __weak typeof (self) weakself = self; the typeof in the notation can also be replaced with the previous version __typeof, but the new notation is recommended, which is TypeOf

Focus on documenting the use of custom fonts

Previously, when configuring the Info.plist file, added a font key-value pair, which can now be used.

1. Add the. TTF font to the project first, and then in the source code of the Info.plist file, add the following code under the Uiappfonts key:

< Key > Uiappfonts</key>    <array>        <  string>fzzy.ttf</string>    </  array>

Of course, you can also find the fonts provided by Application key in list mode, and then add an item to fill in the TTF file name.

2. Use the following code in the appropriate place (for example, the agent method after the Appdelegate application is started):

 for inch [Uifont Familynames]) {        LOG (@ "familyname:%@", familyname);          for inch [Uifont Fontnamesforfamilyname:familyname]) {            LOG (@ "fontname:%@", FontName);        }    }

3. After running the app, look at the font output log in the console, since the Fzzy font is used, the actual name should be similar. So I found afont name like "fzy3jw--gb1-0."

4. You can view fontfzzyfixed macro-defined font display effect

It is important to note that in the same font family, fine, bold, italic, and so on, are different font names, which can be understood as using different fonts. A TTF font file, typically with only one font, which requires viewing the console output's font log.

Use of header files

Create a header file under the supporting files directory:

I put the generic macro definition into the COMMONHEADER.H for unified management and expansion.

Similarly, different types of macro definitions are suggested to be organized into different header files, for example: Stringsheader.h,imagesheader.h,urlsheader.h.

Finally, the integration of all header file references into the precompiled header file PrefixHeader.h the global effect.
