See iOS - Objective-C - 1.6 - Release Notes.

Description

If you have an iOS mobile application written in Objective-C and built with Xcode and you want to view the source code object types and their links with other objects, then you should install this extension. Regarding Front-End to Back-End connections, we support the following cross-technology stacks:


iOS Front-End connected JEE Back-End	iOS Front-End connected Node.js Back-End

How CAST detects XCode projects

The iOS Objective-C extension includes a discoverer that enables Xcode projects to be detected (see com.castsoftware.dmtxcodediscoverer). CAST will search for the project.pbxproj (or a .pbxproj file) - when one is found, the contents are inspected and are used to determine the list of projects present in the root folder.

What are the differences with the extensions for Objective-C and C/C++?

The iOS Objective-C extension supports Objective-C and the com.castsoftware.cpp extension supports C/C++, however, the iOS Objective-C extension has built in support for discovering 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 to take advantage of the built in discovery feature.

Supported Languages

The following languages used to write iOS mobile applications are supported by this extension:

Technology	Supported
Objective-C
C/C++
Storyboard/XIB
Plist

When analysing application with mixed code Objective-C/Swift, links will be created between methods from Objective-C and methods from Swift on both directions.

Function Point, Quality and Sizing 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.

CAST Imaging Core compatibility

Release	Operating System	Supported
8.3.x	Microsoft Windows

Dependencies with other extensions

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

com.castsoftware.dmtxcodediscoverer (to identify Mobile application projects in the CAST Delivery Manager Tool)
com.castsoftware.wbslinker

Download and installation instructions

The extension will be automatically installed by CAST Imaging Console.

Source code discovery

A discoverer (see com.castsoftware.dmtxcodediscoverer) is provided with the extension to automatically detect Xcode code: CAST will search for the project.pbxproj (or a .pbxproj file) - when one is found, the contents are inspected and are used to determine the list of projects present in the root folder. For every Xcode project located, one C/C++ Technology Analysis Unit will be created:

Analysis configuration

For each C/C++ Technology Analysis Unit created for an Xcode project discovered by CAST, the following options should be set as shown below:

Known Limitations

awakeFromNib() method will be linked to NSObject and not the class instance that overwrites this method.
"id" object does not guarantee we could find the real Class object.
