Generic Development Principles

• Common principles for Apple’s native resources or a third party resource:resources or a third‐party resource:– Design patterns

– Licensing

– Device compatibility

Design patterns: • Many of the frameworks use well‐known design patterns for implementing your application. 

• For example, the Model‐ View‐Controller (MVC) design pattern is very common.

Licensing:

• Understanding h h li i d l k f h hi d– how the licensing model works for the third‐party applications, 

d li it ti diti– and any limitations or conditions 

• Be aware of – any restrictions that Apple’s App Store policy might enforce.

Device compatibility: • Writing an application for one device doesn’t mean it will automatically run or behave the same on another ydevice. 

• Take some time to understand h i– the constraints 

– and differences, and design your application for a multi‐device scenario, if applicable. 

• For example, the iPad has more real estate that an iPhone.
