ui 自定义的度如何把握

Great example of custom design of standard UI elements

A UITabbar, a UINavigationBar are basic blocks of construction for me in iOS user interface visual and behavioural language. One can paint a UITabbar or UINavigationBar in a different colour and this is still in line with Apple's HIG. Being just exactly the same as Apple's core application is being kind of dull and at some point is not really a good thing if, as developers or designers, we want to stand out. Looking at many examples like Gift Plan is a very good way to understand how being different from the core can be quite a good thing for the user experience with the application and a very good thing for the developers as they are very successful.

Gift Plan app is a very successful custom design of standard UI elements

Finally, I think to some degree that having a way to express variations of a basic UI element is a sign of life of the platform. iOS is pretty young and there is so much to be done from a UI point of view.
