After reading the “iOS Human Interface Guidelines”, I realized the design of mobile apps basically should follow the guidelines, because the apps are on the iOS platform, as a designer, I should know deeply about what iOS7’s concept, what iOS7’s advantage and restrict, what iOS7 designers care about and what they have done.
I aware that the legibility is so important, because of the mobile screen is smaller in contrast with other interfaces, the text must be legible at every size. I also noticed the iPhone apps’ text size normally controlled in the limit of 22pt to 34pt.
Use plenty of negative space, this rule is what I need to follow, I always try to express more in this limited screen, and the consequence is all information looks like crowed, and no one want to pick the information in such a mess screen. Negative space is very helpful to highlight the real important text.
The confusing part is the more important area is on the upper left corner, I always consider it should be in the center, because of the iPhone’s screen is small. But when the whole page is all texts, like a novel, the most important area must be on the upper left corner, according to people reading habit. Only if images on this view, the most important area should be the center or on the image area, I’m not sure it is right.
I noticed some well-designed apps not follow the frame of UIKit, they do not have navigation bar or tab bar, if they do not want use these tool, they have to design a simple way to let users learn their frame and how to interact part quickly and easily.
