自己写的：

//统计缓存大小

letdataPath =NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory,FileManager.SearchPathDomainMask.userDomainMask,true).first

letfileManager =FileManager.default

letfiles = fileManager.subpaths(atPath: dataPath!)

print(files)

varDocSize:UInt64=0

forfileinfiles!{

iffile.hasSuffix("mp4")||file.hasSuffix("MP4")||file.hasSuffix("Mp4"){

letpath = dataPath!+"/\(file)"

do{

letfloder:NSDictionary=try!fileManager.attributesOfItem(atPath: path)asNSDictionary

//判断后缀是否为MP4，MP3，ACC

print(floder)

DocSize += floder.fileSize()

}catch_{

}

}

}
