不是系统已经自带苹方字体了为什么还要自定义呢？因为苹方字体是在iOS 9引入的，所以如果要支持iOS 9以下都要手动引入苹方字体。
添加苹方字体到项目中
获取苹方字体，Command+G输入
/System/Library/Fonts/PingFang.ttc直接拖到将PingFang.ttc文件拖到项目中
-
在 info.plist文件中添加
Fonts provided by application，并设置字体包名称
添加设置字体
我在iOS 8系统的模拟器中没有在Info.plist中添加
Fonts provided by application，也已经可以正常使用苹方字体了
获取当前系统支持的字体
for (NSString *fontFamilyName in UIFont.familyNames) {
NSLog(@"familyName:%@", fontFamilyName);
for (NSString *fontName in [UIFont fontNamesForFamilyName:fontFamilyName]) {
NSLog(@"fontName:%@", fontName);
}
}
打印结果省略了苹方字体以外的字体

字体册-苹方
设置苹方字体
// 苹方字体，默认为PingFangSC-Regular
UIFont *font = [UIFont fontWithName:@"PingFangSC-Regular" size:14];
NSString *familyName = font.familyName;
NSString *fontName = font.fontName;
NSLog(@"familyName:%@\nfontName:%@", familyName, fontName);
/**
familyName:PingFang SC
fontName:PingFangSC-Regular
*/
扩展
每次都要输入字体名称比较麻烦，并且还要支持iOS 9以下，使用分类方法比较好。
#import <UIKit/UIKit.h>
typedef NS_ENUM(NSInteger, FontWeightStyle) {
FontWeightStyleMedium, // 中黑体
FontWeightStyleSemibold, // 中粗体
FontWeightStyleLight, // 细体
FontWeightStyleUltralight, // 极细体
FontWeightStyleRegular, // 常规体
FontWeightStyleThin, // 纤细体
};
@interface UIFont (Ex)
/**
苹方字体
@param fontWeight 字体粗细（字重)
@param fontSize 字体大小
@return 返回指定字重大小的苹方字体
*/
+ (UIFont *)pingFangSCWithWeight:(FontWeightStyle)fontWeight size:(CGFloat)fontSize;
@end
#import "UIFont+Ex.h"
@implementation UIFont (Ex)
+ (UIFont *)pingFangSCWithWeight:(FontWeightStyle)fontWeight size:(CGFloat)fontSize {
if (fontWeight < FontWeightStyleMedium || fontWeight > FontWeightStyleThin) {
fontWeight = FontWeightStyleRegular;
}
NSString *fontName = @"PingFangSC-Regular";
switch (fontWeight) {
case FontWeightStyleMedium:
fontName = @"PingFangSC-Medium";
break;
case FontWeightStyleSemibold:
fontName = @"PingFangSC-Semibold";

}
UIFont *font = [UIFont fontWithName:fontName size:fontSize];
return font ?: [UIFont systemFontOfSize:fontSize];
