APP中的字体使用

苹果动态字体Demo

APP中添加自定义字体并使用。

效果图

实操：
1、添加自定义字体文件

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 

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);
    }];
}

其他事项
1、字体资源下载
字体吧

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。
