This document discusses how to create a custom transition for modal views in iOS using CocoaPods. It describes a custom segue called ITFScaleModalSegue that animates modal transitions with a scale and fade effect. It provides instructions for creating a podspec file to distribute the custom segue as a CocoaPod, including defining metadata, source code files, dependencies and more. The document concludes by explaining how to submit the podspec to the CocoaPods specs repository.

30. Get hands dirty

32. Creating a
podspec

33. Podspec
$ ~/ pod spec create <pod_name>

34. CocoaPods
Change the authors
Point to the component github repository
Tag a commit and reference it
Add a LICENSE

35. Podspec
Pod::Spec.new do |s|
s.name = "ITFScaleModalSegue"
s.version = "0.0.1"
s.summary = "A custom modal segue with a scale n fade effect."
s.homepage = "https://github.com/lafosca/ITFScaleModalSegue"
s.license = 'MIT'
s.author = { "Arol" => "arol@lafosca.cat",
"David Cortés" => "david@lafosca.cat" }
s.source = { :git => "https://github.com/lafosca/ITFScaleModalSegue.git",
:tag => "0.0.1" }
s.platform = :ios, '6.0'
s.source_files = "ITFScaleModalSegue/ITFScaleModalSegue/*.{h,m}"
s.exclude_files = 'Classes/Exclude'
s.framework = 'QuartzCore'
s.requires_arc = true
end

36. Check
$ ~/ pod spec lint <pod_name>.podspec

37. Submit to CocoaPods
Fork the specs respository
[https://github.com/CocoaPods/Specs]
Add your podspec in /<pod_name>/<tag>/
And then make the pull request!
