MVVM mode developed from scratch for Ios (1)

MVVM mode developed from scratch for Ios (1)

1. previous projects have been using mvc to develop ios and found that ios has a drawback. In mvc, there is a lot of business logic in viewcontroller. When it is constantly modified, it is only a painful process.

2. I have previously worked on wpf and used the mvvm mode. I can put the business logic in the vm mode, and the vm can process the business logic. I have worked on several ios projects and thought about the mvvm mode, but I have never found it. Occasionally, I see an ios project in mvvm mode on the Internet. I will try to do this project from the beginning, and the source code will be published after the project is completed.

3. OK, this mvvm open source project is C-41, interested can go to the Internet search.

4. This project is associated with some class libraries. ios has a cocopods project management tool that can be configured by myself. I have already configured it.

5. Create a new project and create a Podfile in the project directory. Enter

Target "MyTools" do

Pod 'reactivecocoa ', '2. 1.8'

Pod 'libextobjc', '0. 3'

Pod 'reactiveviewmodel', '0. 1.1'

Pod 'uicolor-Utilities ', '1. 123'

Inhibit_all_warnings!

End

Target "MyToolsTests" do

Pod 'specta ',' ~> 0.2.1'

Pod 'expecta ',' ~> 0.2.3'

Pod 'ocmock ',' ~> 2.2.1'

Inhibit_all_warnings!

End

6. Run the pod install command to automatically download and add it to the project.

7. An error will be reported when the project is running. XCTest/XCTest. h file not found built in Xcode 6

8. if you encounter this error, you can check it online. I found a suitable answer in stackoverflow. in my remarks, this website is sometimes very slow in China, it is recommended that you create a software program that turns over the wall. Now I use a cloud ladder, which is easy to configure.

9. In order to fix this for any CocoaPod dependencies you need to add the followingFRAMEWORK_SEARCH_PATHSIn any Pod target that requires XCTest (e.g. Kiwi, Specta, FBSnapshotTestCase, etc ).

$(PLATFORM_DIR)/Developer/Library/Frameworks

10. You need to add $ (PLATFORM_DIR)/Developer/Library/Frameworks to the class Library that reports an error. This is added to BuildSettings-> Search Paths-> Framework Search Paths.

11. Run our mvvm architecture project. A project will be started later.
