Q: 如何在XCode中使用gcc编译生成的.a库文件？ 1. 把你的.a文件添加到^projectName下的任意一個組里（例如默認的Classes組）。 2. 找到Target > ^targetName，在這個^targetName下會有Link Binary With Libraries。把你已經在某組里的那個.a文件拖到Link Binary With Libraries這個Build Phase中。（也可能同時也要添加到某個Copy的Build Phase中...） 3. 提供一個可用的頭文件。 4. Build and Go.

封裝的話，標準的Cocoa做法是用Cocoa Framework。也就是在新建工程的時候，選擇Cocoa Framework。

do shell script " cd ~/Documents/iphone_svn/iphone/Projects/GTLib; ar crv ./lib/libgtlibd.a ./build/GTLib.build/Debug-iphoneos/GTLib.build/Objects-normal/armv6/GT*.o; ar crv ./lib/libgtlibsd.a ./build/GTLib.build/Debug-iphonesimulator/GTLib.build/Objects-normal/i386/GT*.o; ar crv ./lib/libgtlib.a ./build/GTLib.build/Release-iphoneos/GTLib.build/Objects-normal/armv6/GT*.o; ar crv ./lib/libgtlibs.a ./build/GTLib.build/Release-iphonesimulator/GTLib.build/Objects-normal/i386/GT*.o; " 给你个例子，你把路径什么的改掉就可以了 2. To link to a .a library like this in Xcode you need to: Double-click on your target or application in Xcode to open the Info window Switch to the "Build" tab Add -lfftw3 to "Other Linker Flags" (under "Linking") Add the path to your library to the "Library Search Paths" (under "Search Paths"). In your case this will be /usr/local/lib We use FFTW (it's great by the way), this works for us!
