字体名称打印 及添加自定义字体

    NSArray *familyNames = [UIFont familyNames];
    for( NSString *familyName in familyNames ){
        printf( "Family: %s 
", [familyName UTF8String] );
        NSArray *fontNames = [UIFont fontNamesForFamilyName:familyName];
        for( NSString *fontName in fontNames ){
            printf( "	Font: %s 
", [fontName UTF8String] );
        }
    }

添加自定义字体：

1.导入xxx.tff文件到项目文件夹

2.在plist添加UIAppFonts项，在该项的子项添加xxx.tff

3.build phases->copy bundle resources里添加xxx.tff
