Xcode reference a framework instead of link binary with libraries

问题

When developing cocoa touch framework, how can i use code from third party framework by referencing it other then including it in the "link binary with libraries" option?

I dont want to link to binary in order to prevent symbol conflicts between hosting project and the framework (project which will use the framework)

Additionally i will need the framework code to use the hosting project reference to the third party framework, how can it be done?

Or should i take different approach for example static framework (i am not familiar with the small differences of the two)

回答1:

1. Select the target you want to modify and reveal its build phases.
2. Expand the Link Binary With Libraries build phase to view the frameworks currently linked by the target.
3. If the framework you want to weakly link to is listed in the Link Binary With Libraries build phase, select it, and choose Edit > Delete to remove it. Now you can tell the linker to use weak linking for that framework.
4. Select the target, open its Info window, and click Build.
5. To the Other Linker Flags build setting, add the following command-line option specification, where is the name of the framework you want to weakly link to:

-weak_framework <framework_name>

6. Build your product.

Here is a docs section for that. Docs
