The beginning of the nonsense: simply create a keyboard extension class available for use by the system, it is the hand of the code world, useless world.
First, to achieve the effect display
Since the third-party keyboard is added in the phone Settings, you can use a custom keyboard in wechat, isn’t it interesting?
Second, create a project
1: Create a new project first
2: Click CreateTarget
Select a custom keyboard
After completion, the project will have more folders as shown in the figure.
Three, code implementation
KeyboardViewController file
1:KeyboardViewController.h
KeyboardViewController inherits from UIInputViewController in iOS
2:KeyboardViewController.m
Step 1: DeclarationWishView 类
It is the carrier of the surrounding wall and records the current azimuth Angle range, whether it has been used and the content
MinAngle: the minimum azimuth range Angle
MaxAngle: indicates the maximum azimuth range Angle
The rotation Angle of the center “tank” is judged between the maximum and minimum Angle to be the current brick
Step 2 createnextKeyboardButtonButton to ensure that the keyboard can be switched
You must switch keyboard input methods; otherwise, other input methods may be affected.
Step 3. Draw a picture: “ME” surrounded by bricks
Start by declaring some properties
Draw the tanks that are surrounded
The effect
Handle tank tap event, rotate random interval Angle
Handling fire incidents
Explosion effect
Circled in red is the text content to the current as the first responder input box!
Fourth, summary and thinking
After the app runs successfully, you need to add the current custom keyboard to the phone Settings to use it.
Don’t laugh at bad code.
