ios 怎样判断某个文件是否存在

- (void)createFileDirectories

{

// 判断存放音频、视频的文件夹是否存在，不中和蠢存在则卖陪创建棚基对应文件夹

NSFileManager *fileManager = [NSFileManagerdefaultManager]

BOOL isDir = FALSE

BOOL isDirExist = [fileManager fileExistsAtPath:DOCUMENTS_FOLDER_AUDIOisDirectory:&isDir]

if(!(isDirExist &&isDir))

{

BOOL bCreateDir = [fileManager createDirectoryAtPath:DOCUMENTS_FOLDER_AUDIOwithIntermediateDirectories:YESattributes:nilerror:nil]

if(!bCreateDir){

NSLog(@"Create Audio Directory Failed.")

}

NSLog(@"%@",DOCUMENTS_FOLDER_AUDIO)

}

isDir = FALSE

isDirExist = [fileManager fileExistsAtPath:DOCUMENTS_FOLDER_VEDIOisDirectory:&isDir]

if(!(isDirExist &&isDir)){

BOOL bCreateDir = [fileManager createDirectoryAtPath:DOCUMENTS_FOLDER_VEDIOwithIntermediateDirectories:YESattributes:nilerror:nil]

if(!bCreateDir){

NSLog(@"Create Audio Directory Failed.")

}

NSLog(@"%@",DOCUMENTS_FOLDER_VEDIO)

}

}

用cp命令冲汪！

给你举个例子吧！把/home/a下的所有岩判扒文件拷贝到/usr/local/src下：

cp /home/a/* /usr/粗昌local/src/a
