Target audience:

Users of the extension providing support for applications written in Objective-C.

Summary: This document provides information about the extension supporting applications written in Objective-C.

What's new: Two new quality rules was added; "Avoid using risky cryptographic hash" and "Avoid using unsecured cookie"

Description

This extension provides support for applications written in Objective-C.

In what situation should you install this extension?

If your application contains Objective-C source code and you want to view these object types and their links with other objects, then you should install this extension.

Note that while this extension does provide some support for C/C++, official support for C/C++ is provided by the C and Cpp Analyzer embedded in CAST AIP and available as an extension.

What are the differences with the CAST AIP extension for iOS?

The CAST AIP extension for iOS - Objective-C also supports Objective-C, however, the iOS extension has built in support for discovering (in the CAST Delivery Manager Tool) XCode projects that are primarily used to build Mobile applications for the iOS Operating System. Therefore, if your project is an XCode project, you should use the iOS - Objective-C extension instead to take advantage of the built in discovery feature.

Function Point, Quality and Sizing support

This extension provides the following support:

Function Points (transactions): a green tick indicates that OMG Function Point counting and Transaction Risk Index are supported
Quality and Sizing: a green tick indicates that CAST can measure size and that a minimum set of Quality Rules exist

Function Points (transactions)	Quality and Sizing

CAST AIP compatibility

This extension is compatible with:

CAST AIP release	Supported
8.3.x
8.2.x
8.1.x
8.0.x
7.3.x

Supported DBMS servers

This extension is compatible with the following supported DBMS servers:

CAST AIP release	CSS	Oracle	Microsoft
All supported releases

Prerequisites

An installation of any compatible release of CAST AIP (see table above)

Dependencies with other extensions

Some CAST extensions require the presence of other CAST extensions in order to function correctly. The Objective-C extension requires that the following other CAST extensions are also installed:

Web services linker service (internal technical extension)

Note that when using the CAST Extension Downloader to download the extension and the Manage Extensions interface in CAST Server Manager to install the extension, any dependent extensions are automatically downloaded and installed for you. You do not need to do anything.

Packaging, delivering and analyzing your source code

Once the extension is installed, no further configuration changes are required before you can package your source code and run an analysis. The process of packaging, delivering and analyzing your source code is as follows:

Packaging and delivery

Using the CAST Delivery Manager Tool:

create a new Version
create a new Package for your Objective C source code using the Files on your file system option:

Define the root folder of your Application source code:

Run the Package action: depending on this type of project you are packaging, the CAST Delivery Manager Tool will either discover a project or not. For non-iOS projects, no project will be discovered:

Deliver the Version

Configuring the source code in the CAST Management Studio

Using the CAST Management Studio in the Application editor:

Accept and deploy the Version in the CAST Management Studio. Depending on the type of project that has been packaged, Analysis Units will have been created automatically or not:

*

If your source code contains Non-iOS projects, then no Analysis Units will have been automatically created in the Current Version tab - this is the expected behaviour:

You will now need to create an Analysis Unit for each of your projects. In the Current Version tab, add a new Analysis Unit selecting the Add new C/C++/Objective-C Analysis Unit option:

Edit the new Analysis Unit and configure in the Source Settings tab:

a name for the Analysis Unit
define the location of the deployed project source code (the CAST Management Studio will locate this automatically in the Deployment folder):

You now need to change the analyzer engine to the new Clang based analyzer.
Move to the Analysis tab.
Change the Analyzer to invoke option to the Clang-based analyzer option as shown below:

Note that it is possible to change this option at Application level, however, this will change the option for all C/C++/Objective-C Analysis Units, which may not be appropriate.

Analysis/snapshot generation

Run a test analysis on the Analysis Units
Make sure you have manually run the Import Assessment Models option.
Generate a new snapshot.

What results can you expect?

Once the analysis/snapshot generation has completed, you can view the results in the normal manner:
