iOS 自定义-苹方字体的使用

发表于 | 分类于 | | 阅读次数:

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

UIFont *font = [UIFont fontWithName:@"PingFangSC-Regular" size:14];
NSString *familyName = font.familyName;
NSString *fontName = font.fontName;
NSLog(@"familyName:%@\nfontName:%@", familyName, fontName);
/**

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。
