A framework is a dynamic library and resources for that library, such as images and localization strings. Frameworks have the file extension <tt>.framework</tt>.
   
On the iPhoneOS there are 2 kinds of frameworks: '''public frameworks''' and '''private frameworks'''. Public frameworks are those ones endorsed by Apple and are allowed to be used in AppStore apps. Private frameworks are intended to be used only by original apps, and are more unstable against firmware changes, but many of the interesting features are in the private frameworks.

In [[iOS]] there are two kinds of frameworks: '''public frameworks''' and '''private frameworks'''. Public frameworks are allowed to be used in App Store apps. Private frameworks are intended to be used only by Apple's apps, and are more unstable against firmware changes, but many of the interesting features are in the private frameworks.

Since iOS 3.1, all default (private and public) libraries have been combined into a big cache file in <tt>/System/Library/Caches/com.apple.dyld/dyld_shared_cache_armX</tt> to improve performance. See [http://iphonedevwiki.net/index.php/Dyld_shared_cache dyld_shared_cache] for more details. The original libraries are no longer useful for non-on-device-developers, so they are eliminated from the system. The framework folders still contain other resources, such as localization strings.

A framework is a dynamic library and resources for that library, such as images and localization strings. Frameworks have the file extension .framework.

In iOS there are two kinds of frameworks: public frameworks and private frameworks. Public frameworks are allowed to be used in App Store apps. Private frameworks are intended to be used only by Apple's apps, and are more unstable against firmware changes, but many of the interesting features are in the private frameworks.

Since iOS 3.1, all default (private and public) libraries have been combined into a big cache file in /System/Library/Caches/com.apple.dyld/dyld_shared_cache_armX to improve performance. See dyld_shared_cache for more details. The original libraries are no longer useful for non-on-device-developers, so they are eliminated from the system. The framework folders still contain other resources, such as localization strings.

Private Frameworks

See /System/Library/PrivateFrameworks.

Public Frameworks

Resources for public frameworks can be found inside /System/Library/Frameworks.
