j2objc0.9.5 using J2OBJC in two--xcode

There are two ways of using J2OBJC in Xcode: External build and Xcode build Rule.

Xcode Build Rules mode:

First, create a new project

Open Xcode and choose New Project-Choose a application, such as single View application.

Product name and organization name are optional. My project is named Java2objctest.

Second, add J2OBJC Build Rule

1. Create a new Settings.xcconfig file with the following contents:

J2objc_home = ${j2objc_install_dir}/= $ (inherited) "${j2objc_home}/include" "${derived_files_dir}"  = $ (inherited) "${j2objc_home}/lib"= $ (inherited)-L "Z"-L "Jre_emul"-L "Icucore";

The j2objc_home is set to the Dist directory compiled by J2OBJC.

2. Use this file as a compiled configuration:

Both the project--project--info,debug and release are set to this configuration file.

3. Add Custom Build Rule:

Engineering-Engineering Target--build Rules, click the plus sign to create a new rule.

Process Select Java source files

Using the custom script, enter in the following input box:

if [!-F "${J2OBJC_HOME}/J2OBJC"]; Then echo "J2objc_home not correctly defined in Settings.xcconfig, currently set to ' ${j2objc_home} '"; Exit 1; fi;" ${J2OBJC_HOME}/J2OBJC "-D ${derived_files_dir}-sourcepath" ${project_dir}/classes "--no-Package- Directories--prefix othello.engine=oe-g ${input_file_path};

In output files, click the plus sign to add two lines:

${derived_files_dir}/${input_file_base}.h${derived_files_dir}/${input_file_base}.m

The result should be this:

4. Adding Java code and dependent libraries

Create a new Java source folder in the project and add Java code to it, such as I added Skylead/sign/signtool.java in TESTJ2OBJC.

The code is as follows:

 Package skylead.sign;  Public class SignTool {    publicstatic  string getsign (String sign) {        = ' sign is: ' +  sign;                 return result;}    }

Introduce the header file where you need to call this method:

#import "SignTool.h"

You can then use the static methods provided by this class:

nsstring* test = [Skyleadsignsigntool getsignwithnsstring:@ "my Sign"];

Test returns the result: Sign Is:my sign
