Zimt is a collection of various utilities that should help you with iPhone Objective-C development. Pretty much like Facebook's Three20, but less UI-Oriented
Adding Zimt to your project
Drag and drop Zimt.xcodeproj to your project's "Groups & Files" sidebar. Make sure "Copy items" is unchecked and "Reference Type" is set to "Relative to Project"
From newly added Zimt.xcodeproj, drag and drop libZimt.a to "Targets" > Your application target > "Link binaries with Library"
Under "Targets", right click your Application target, choose "Get Info" and under "General" tab add direct dependency to "Zimt"
Include Zimt headers in your project: Under "Project" > "Edit Project Settings", go to "Build" tab. Search for "Header Search Paths" and double-click it. Add the relative path from your project's directory to the "zimt/src" directory
Setup the debug macro: in "Projects" > "Edit Project Settings", under "Build tab", choose "Debug Configuration". Search for "Preprocessor macros", add DEBUG=1
If you're using ZTWebSocket, you need to add the CFNetwork to your project. Right click on the "Frameworks" group in your project (or equivalent) and select "Add" > "Existing Frameworks". Locate CFNetwork.framework and add it to the project.
CLLocationManager subclass that can read a list of waypoints from a file and simulate location updates. Meant to be used on simulator for testing. See samples/FakeLocation
