实操：  
1、添加自定义字体文件  
![在这里插入图片描述][20181204000413784.png]  
2、配置项目`plist`文件  
设置属性`Fonts provided by application`类型为`NSArray`

3、配置`Build Phases`

4、实现字体设置

NSString *fontName = xxxx;
    UIFont *font = [UIFont fontWithName:fontName size:15.0];

代码实现示例

#import <Foundation/Foundation.h>
    
    NS_ASSUME_NONNULL_BEGIN
    
    #define SaveFont(name) [FontUtil saveFontName:name]
    #define SetFont(size) [FontUtil fontWithSize:size]
    
    @interface FontUtil : NSObject
    
    /// 保存字体
    + (void)saveFontName:(NSString *)name;
    /// 获取字体
    + (UIFont *)fontWithSize:(CGFloat)size;
    
    /// 显示所有字体
    + (void)showFonts;
    
    @end
    
    NS_ASSUME_NONNULL_END

#import "FontUtil.h"
    
    #ifdef DEBUG
    #define NSLog(FORMAT, ...) fprintf(stderr,"%s\n",[[NSString stringWithFormat:FORMAT, ##__VA_ARGS__] UTF8String]);
    #else
    #define NSLog(...)
    #endif
    
    
    @implementation FontUtil
    
    + (void)saveFontName:(NSString *)name
    {
        if (name == nil || name.length <= 0) {
            name = @"";
        }
        [[NSUserDefaults standardUserDefaults] setObject:name forKey:@"fontName"];
        [[NSUserDefaults standardUserDefaults] synchronize];
    }
    
    + (UIFont *)fontWithSize:(CGFloat)size
    {
        if (size <= 0.0) {
            size = [UIFont systemFontSize];
        }
        NSString *name = [[NSUserDefaults standardUserDefaults] objectForKey:@"fontName"];
        if (name == nil || name.length <= 0) {
            return [UIFont systemFontOfSize:size];
        }
        UIFont *font = [UIFont fontWithName:name size:size];
        return font;
    }
    
    + (void)showFonts
    {
        //
        UIFont *font = [UIFont systemFontOfSize:[UIFont systemFontSize]];
        NSLog(@"current font: %@", font);
        //
        NSArray *fonts = [UIFont familyNames];
        [fonts enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
            NSLog(@"%@: %@", @(idx), obj);
        }];
    }
    
    @end

其他事项  
1、字体资源下载  
[字体吧][Link 1]

2、使用Mac字体册  
步骤：程序坞——Launchpad——其他——字体册——查看字体——菜单栏——文件——导出字体

3、自定义字体实际名称查找及使用  
添加自定义到项目中后，不清楚字体的实际名称？怎么办？  
解决方法把添加自定义字体前后的所有字体名称打印出来，通过使用Xcode自带的文件对比工具`FileMerge`对比两个文件得出。
