Sometimes we need to add other sub-projects in a main project, to write modifications to the sub-project, or to take advantage of the library files in the subproject, and so on, we need to use the project nesting. Step: (see picture to speak) 1. Create a new main project, called TESTTTTT, to create a new static framework project named MyLibrary. Put the two project files in a folder, such as:2. In Testtttt, do the following: The sub-project in the lower left corner "+" inside execute Add File to find MyLibrary in the project file added. 3. Add Dependencies:4. Add a path 5. You're done, now test to see if you can call a class in a sub-projectAdd header file: (as we add sub-works directly under AddFile)#import <MyLibrary/MyView.h>
Initializes an instance of://Add an external engineering test
MyView*view=[[MyViewAlloc]initwithframe:cgrectmake (100 , 100 100100 [selfview Addsubview:view];
Run the project, the view is displayed, no problem. callout: When using this method mylibrary can only be opened once, that is, in the case of TESTTTTT Open, mylibrary can no longer be opened, in order to avoid conflicts
