How do you install a pod's sub spec without installing the whole pod?

Question

I just want one subspec of one library, for example, the nimbus podspec is as follows:

pod search Nimbus

-> Nimbus (1.0.0)

An iOS framework whose growth is bounded by O(documentation).

I just want to install the Nimbus/core, what should the podfile contain?

Answer 1

just use following line in your pod spec

pod 'Nimbus/Core', '= 1.0.0'

Complete pod spec sample:

platform :iOS,'6.0'

pod 'Nimbus/Core', '= 1.0.0'
