   3. Generate xcode project  
      - for arm64:  
-     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$axis_ROOT/cmake/ios.mini.cmake -DCMAKE_OSX_ARCHITECTURES=arm64```
+     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AXIS_ROOT/cmake/ios.mini.cmake -DCMAKE_OSX_ARCHITECTURES=arm64```
      - for armv7,arm64 combined:  
-     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$axis_ROOT/cmake/ios.mini.cmake "-DCMAKE_OSX_ARCHITECTURES=armv7;arm64"```
+     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AXIS_ROOT/cmake/ios.mini.cmake "-DCMAKE_OSX_ARCHITECTURES=armv7;arm64"```
      - for simulator x86_64:  
-     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$axis_ROOT/cmake/ios.mini.cmake -DCMAKE_OSX_ARCHITECTURES=x86_64``` 
+     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AXIS_ROOT/cmake/ios.mini.cmake -DCMAKE_OSX_ARCHITECTURES=x86_64``` 
 
   4. After cmake finishes generating, you can open the xcode project at ```build``` folder and run cpp-tests or other test targets.

   3. 生成xcode工程, 进入axis根目录执行如下命令之一:  
      - for arm64:  
-     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=cmake/ios.mini.cmake -DCMAKE_OSX_ARCHITECTURES=arm64```

   4. 之后就可以用xcode打开, 选择cpp-tests编译运行
