The Fish Finder API for iOS is a port of the STFishFinder API to Apple's iOS platform, to allow use of the Sifferman Technology FE2 black box fish finder with the iPhone, iPod Touch, and iPad products.

The Fish Finder API for iOS combines the C++11-based STFishFinder API with a wrapper layer written in Objective C++. The wrapper layer presents an Objective C-style class interface to the application program. STFishFinder error codes are translated to NSError objects by the wrapper. The wrapper layer also provides connectivity to the Wi-Fi hardware in an iOS device through the CFNetwork API provided in the iOS SDK. In addition, the wrapper layer makes use of the NSNotification API to send notifications to user interface delegates within the application program when a STFishFinder API event invokes one of the callbacks.
