Confused as to how to install using CocoaPods

[tachang]

I have read numerous issues on how to install but am failing pretty badly.

I have a pure objective-c project and am using CocoaPods. I believe this is a very common scenario.

So first thing I do is look at "CocoaPods Install" of the README and add it into my Podfile:

platform :ios, '9.0'
pod 'Charts'
use_frameworks!

Do a pod install and everything works.

I even am able to create a view and use Module 'Chart' and BarChartView as the class. And it compiles and I see "No chart data available" in orange.

However now I am trying to add a reference to that chart but I can't figure out what to import. I've tried to import lots of different things but none of it is resolving. What do I do in this case?

The name you use for import is the module name so for this library it's import Charts

Okay I believe what is confusing is that this is the correct way to do it but you need to add the line

@import Charts;

to your .h file.

What was confusing to me is that when I saw "@import" it looked kinda like Swift syntax/code so I ignored it thinking I had to do something like #import <Charts/Charts.h> or something like that. When in fact "@import Charts" is a perfectly valid statement and will compile (is it converting it to objective-c in the background or is that actually valid? Like is the preprocessor converting it).

Thank you.

It's perfectly valid ObjC, since iOS 8 where Apple have introduced Modules.
Instead of #includeing specific headers and looking at the docs to figure out which- you can @import a module.
This also layed the ground for Swift's import and is the reason that you don't worry about .h files in Swift.
