为什么CocoasPod会增加IPA规模？ 如何减小尺寸？

Question

CocoasPod is good, But sometimes it's not.
Why? Because there is a flag call "-ObjC" in your project.
It will pull ALL OBJECT FILES into your resulting binary.

For example, an empty project with "pod 'AFNetworking'" and the flag "-ObjC" is on, that will cause the binary will be 7MB. 7MB for an empty project, that's suck.

Some frameworks like Google Map SDK need the flag "-ObjC" is on.
So, if your project with "AFNetworking pod" and "Google Map SDK", it will cause the binary will be 17MB.

So my question is:
How can I turn off the "-ObjC" flag for special Library?
For example, just keep the "-ObjC" for Google Map SDK, but turn it off on AFNetworking.

Answer 1

You should try the answer to this question so as to reduce the .ipa size.

In general, adding a static library to your project in Objective-C will pull ALL OBJECT FILES into your resulting binary because cocoa pods installation adds -ObjC flag to your linker settings, and as stated in linker manual:

 -ObjC Loads all members of static archive libraries that implement an Objective-C class or category. 

This flag included to solve problem with linking categories, because by default linker will not include object files containing only categories into resulting binary.
