我写#import <AVFoundation/AVFoundation.h>
在我的代码中,但是当我编译它时出现以下错误: 'AVFoundation/AVAsset.h' 文件未找到我还收到以下警告:
ld: warning: ignoring file /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/System/Library/Frameworks//AVFoundation.framework/AVFoundation, file was built for unsupported file format which is not the architecture being linked (armv7)
请帮助
