iOS 自定义-苹方字体的使用

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 

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";
            break;
        case FontWeightStyleLight:
            fontName = @"PingFangSC-Light";
            break;
        case FontWeightStyleUltralight:
            fontName = @"PingFangSC-Ultralight";
            break;
        case FontWeightStyleRegular:
            fontName = @"PingFangSC-Regular";
            break;
        case FontWeightStyleThin:
            fontName = @"PingFangSC-Thin";
            break;
    }
    
    UIFont *font = [UIFont fontWithName:fontName size:fontSize];
 
    return font ?: [UIFont systemFontOfSize:fontSize];
}
