objective c - What is the recommended method of styling an iOS app?

Question

What is the recommended method of styling an iOS app? For example, if there are multiple labels or text views how can updating font style/color at one place update the style/color at all other places?

I know sub classing could be one way... is there any other way?

Answer 1

You could import a standard header file into all your controllers with several constants set for styling... example:

Styles.h

#define kFontSize 14
#define kFontFamily @"Helevetica"

Controller

#import "Styles.h" // at the top

myLabel.font = [UIFont fontWithName:kFontFamily size:kFontSize];

I personally think Interface Builder is the best way to style, however this answers your question directly.
