1.HTML5 slow execution and poor user experience
2. Native application development, that is, iOS and Android developed separately, need two technical staff, late code maintenance difficult, it is difficult to achieve unity.
3.xamarin is a C # solution for a fee. Xamarin.form is a cross-platform interface for users. Add a group heard very pit, not mature, give up to continue to study.
4. Hybrid development, that is, using the HTML5 interface, respectively, the iOS and Android to provide the native interface. This is the same problem as the native application.
5.cocos2d-x,unity3d is a game development engine. Looked at some of the controls to check the data, there are few people using the game engine to develop common applications.
6.crossapp Open Source C + + cross-platform engine, is developing, the official has to provide on-line product source learning. This is not mature, but I think since it is open source encountered
The problem should be solved, the efficiency of C + + is not a problem, the code can also achieve unity in no other better choice, first select it.
