富文本离不开文字，下面我们学下字体Font

字体内容较多，我们从以下方面学下。

1.Font Types

1
CFTypeID CTFontGetTypeID( void )  获取font  CFTypeID

2.Font Constants

kCTFontCopyrightNameKey 版权key
kCTFontFamilyNameKey family（家族） key
kCTFontSubFamilyNameKey subfamily（子家族）key
kCTFontStyleNameKey 字体style key
kCTFontUniqueNameKey 独一无二key（value不是真的独一无二，不应该假设唯一）
kCTFontFullNameKey 字体全名key
kCTFontVersionNameKey 字体版本号key
kCTFontPostScriptNameKey 字体补充说明key
kCTFontTrademarkNameKey 商标key
kCTFontManufacturerNameKey 制造商key
kCTFontDesignerNameKey 设计者key
kCTFontDescriptionNameKey 字体描述key
kCTFontVendorURLNameKey 供应商url key
kCTFontLicenseNameKey 许可证key
kCTFontLicenseURLNameKey 许可证url key
kCTFontSampleTextNameKey 简单text key
kCTFontPostScriptCIDNameKey 补充说明CID key

这些key 暂时不知道干嘛用的。

CTFontDescriptor.h学习

该类从以下四个方面来学习。

1.Descriptor Types

1
CFTypeID CTFontDescriptorGetTypeID( void ) CT_AVAILABLE(10_5, 3_2);

2.Descriptor Constants

ke’y value 解释
kCTFontURLAttribute CFURLRef 通过 descriptor 访问字体的url
kCTFontNameAttribute CFStringRef 先从 PostScript arr 中找， 没发现在从 family 数字找，没发现 用 display name 。， 如果还是从字体列表中没找到，默认返回 Helvetica 字体
kCTFontDisplayNameAttribute CFStringRef 这个返回display name 大多数是 the full name。
kCTFontFamilyNameAttribute CFStringRef 返回 family name
kCTFontStyleNameAttribute CFStringRef 返回 the style name of the font。代表设计者对该字体样式的描述。
kCTFontTraitsAttribute CFDictionaryRef 返回改字体的特性 traits 字典。
kCTFontVariationAttribute CFDictionaryRef 不知道啥用
kCTFontSizeAttribute CFNumberRef 返回字体的大小
kCTFontMatrixAttribute CFDataRef 该data是 CGAffineTransform信息
kCTFontCascadeListAttribute CFArrayRef 级联表格数组，具体干嘛的不知道。看结果在说
kCTFontCharacterSetAttribute CFCharacterSetRef
kCTFontLanguagesAttribute CFArrayRef
kCTFontBaselineAdjustAttribute CFNumberRef
kCTFontMacintoshEncodingsAttribute CFNumberRef
kCTFontFeaturesAttribute CFArrayRef
kCTFontFeatureSettingsAttribute
kCTFontFixedAdvanceAttribute CFNumberRef
kCTFontOrientationAttribute CFNumberRef
kCTFontFormatAttribute CFNumber
kCTFontRegistrationScopeAttribute CTFontManagerScope
kCTFontPriorityAttribute
kCTFontEnabledAttribute
kCTFontDownloadableAttribute
