您可以将标准头文件导入所有控制器，并为样式设置几个常量...示例：

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"

控制器

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

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

我个人认为Interface Builder是***的造型方式，但这会直接回答你的问题。

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