Xcode: how to link dylib library files

When linking with external dylib for an Xcode project. You might get this error:

dyld: Library not loaded: libXXX.dylib

Referenced from: .../Developer/Xcode/DerivedData/quack-gpfxwhnflltwzkdnerqlydkddvbj/Build/Products/Debug/zzz

Reason: image not found

Xcode 4.0 solution

1) click on the project in the side pane to bring up the properties.

2) click on "Target"

Checking the library:

3) In "Build Settings"

4) Using search, enter "library". There should be a path automatically set in the field for "Library Search Paths" if you added the dylib to your project.

Add a copy files phase:

3) In "Build Phases"

4) Click "Add Build Phases"

5) Click "Add Copy Files"

6) In "Destination" select "Executables"

7) Add entry by clicking the "+"

8) Choose the .dylib file from your project or manually locate it.

这种做法实际上是将dylib放在生成的app文件目录下（程序首次运行时，会将工程中的dylib文件copy到app目录）。经过测试，完全没有必要将dylib文件导入工程，直接拖到最终app目录下就可。
