IOS ProtocolBuffer setup and demo, iosprotocolbuffer

This time I set up the ProtocolBuffer compiler for iOS and encountered many problems when compiling *. proto Source files into *. pbobjc. h and *. pbobjc. m files!

There was no problem when building the pb compiler. After compiling the *. proto file, I used cocoaPods to integrate ProtocolBuffers into my project,

During cocoaPods integration, I tried two libraries:

Https://github.com/google/protobuf.git,

The other one is:

Https://github.com/alexeyxo/protobuf-objc.git

However, an error is always reported during running:

It will be reported that the ProtocolBuffer library file cannot be found;

Report version mismatch later: This file was generated by a different version of protoc which is incompatible with your Protocol Buffer library sources;

The attribute data format does not exist and does not match.

 

Finally, I had to give up CocoaPods and drag the library downloaded from https://github.com/google/protobufinto the project. This is a good deal!

Briefly describe the installation process of the pb compiler and the demo after compilation:

 

I. Environment installation: Install the pb Compiler

1. Slave

For: https://github.com/google/protobuf/releases/download/v3.1.0/protobuf-objectivec-3.1.0.zip

2, extract the package, assuming that the decompressed folder name: protobuf-objectivec-3.1.0,
Open the terminal, enter the folder protobuf-objectivec-3.1.0, and execute the following commands in sequence:

./configuremakemake checksudo make install

If the compilation succeeds, you can use the protoc command to convert the. proto file to source code files in different languages.

 

2. Create a new project, import the pb library, compile the proto file, and use the process

1. Download the source code from https://github.com/google/protobuf.gitand decompress it. The source code that supports different languages appears,

We only need the folder name that supports objc: objectivec,

　　

 

2. Create a project named Tan_ProtocolBuffer and create a folder named protocolbuf. Copy the pb source code in step 1 to this folder:

　　

 

3. Use Xcode to open the project, click "+" in the lower left corner, and reference the protocolBuffer source file to the project.

4. Select the project: targets-> Build Phases-> Link Binary With Libraries, reference the source code static library file: libProtocolBuffers.

　　

 

5. Search for the static library header file in the Project Settings (the pb file is in the protocolbuf folder ):

Targets-> Build Setting-> Search Paths-> Header Search Paths, write: $ (PROJECT)/protocolbuf

　　

 

　　

6, write the test file *. proto, such as creating a new file Person. proto, according to the official standard syntax https://developers.google.com/protocol-buffers/ to write general code,
Enter the directory of the Person. proto file on the terminal, and use the protoc command: protoc *. proto -- objc_out = ../Pro_out to compile the file.
Compile the Person. proto file into Person. pbobjc. h and Person. pbobjc. m. The generated file is in the Pro_out folder.
If there is a syntax problem with the Person. proto Source file, an error will be reported during compilation. If no prompt is displayed during compilation, the compilation is successful:
Compile *. pbobjc. h and *. pbobjc. m is dragged into the project. Because arc is not supported, you need *. pbobjc. m sets-fno-objc-arc, and then you can use it.

As follows:

　　　　

 

 

 

 

 

 

7. Compile the test code and use the Person class for data serialization and deserialization:
