Contrasting the different ways of adding an existing framework to Xcode

Question

In Xcode (specifically v3.2.4), there are two ways of adding an external framework to a solution

1. Dragging and dropping a framework from finding into XCode
2. Clicking on add existing, and selecting one

Surprisingly, the two ways do not yield the same result (I learned this the hard way). Here is a diff of the two methods on the contents of project.pbxproj in the .xcodeproj package:

By dragging 005DB04C1255606C005A66F1 /* GHUnitIOS.framework */ = {isa = PBXFileReference; lastKnownFileType = wrapper.framework; path = GHUnitIOS.framework; sourceTree = ""; };

By adding existing 005DB06C12556222005A66F1 /* GHUnitIOS.framework */ = {isa = PBXFileReference; lastKnownFileType = wrapper.framework; name = GHUnitIOS.framework; path = Library/Frameworks/GHUnitIOS.framework; sourceTree = DEVELOPER_DIR; };

A different value for the path and a different one for the source tree is produced.

Does anyone know what these differences are, and what the advantage of each method is?

Answer 1

These are just different defaults for how the path to the framework is defined. You can change these by doing a "Get Info" on the framework and setting the "Path Type" popup in the "General" tab accordingly.
