编译移动IOS的2.7.1版本；源码从github下载； 

output_dir="${HOME}/Desktop/freetype"
min_iphoneos="7.0"
AR_POS=“/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ar“
CC_POS=“/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang”  
export CC=$CC_POS  
ARCH=“arm64“  #在iPhone下使用静态库时,指定指令集ARM64,IPAD armv7.

export LDFLAGS=“-arch $ARCH -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk -miphoneos-version-min=$min_iphoneos“#指定链接选项
./configure --host=“aarch64-apple-darwin” --enable-static=yes --enable-shared=no #生成静态链接库,编译出来的库文件执行的主机类型
make clean
make
mkdir -p $output_dir && cp objs/.libs/libfreetype.a "$output_dir/libfreetype-${ARCH}.a"

2.7.1编译的时候Freetype不支持bitcode属性；

使用：在配置文件info plist 上添加Fonts Provided by application ,在里边添加字体库支持

 

 

 编译使用的时候需要加上一些附加依赖库：libbz2.tbd,libz.tbd

写字需要使用的函数：

?

1 2 3 4 5 6 7 8 9 10 11

FT_init_freetype,创建,装载渲染模块,字体驱动模块,助手模块等 通过流FT_STREAM的形式读取字体文件 FT_new_face则会根据参数2的文件路径,创建文件流对象   FT_Set_Pixel_Sizes( face, 0,16 ); 设置字体像素大小16*16(以像素的形式设置字符大小)   FT_Set_Char_Size(   face    , 0    ,  16*64,    300, 300 );   在300*300dpi分辨率的设备上将字符大小设置成16*16pt(以点的形式设置字符的大小)   FT_BITMAP结构体内的 buffer存放字体的点阵,rows ，width存放点阵的宽,高. 逐行输出即可得到字体的点阵数据(8位抗锯齿模式FT_RENDER_MODE_NORMAL渲染点阵,点的数值0-255) FT_SET_Transform 形变：仿射变换
