寫在前面
弄了下個(gè)人站...防止內(nèi)容再次被鎖定...所有東西都在這里面

個(gè)人博客
所有方法
都很簡(jiǎn)單跨释，大概記錄一下膛锭，寫文件并沒(méi)有是追加的方式而是簡(jiǎn)單的覆蓋
//創(chuàng)建文件夾
- (BOOL)creatDir:(NSString*)newDirName at:(NSString*)dirName ;
//創(chuàng)建文件
- (BOOL)creatFile:(NSString*)fileName at:(NSString*)dirName ;
//寫文件-字符串
- (BOOL)writeString:(NSString*)string inFilePath:(NSString*)filePath;
//寫文件-字典
- (BOOL)writeDict:(NSDictionary*)dict inFilePath:(NSString*)filePath ;
//寫文件-數(shù)組
- (BOOL)writeArray:(NSArray*)array inFilePath:(NSString*)filePath ;
//讀文件
- (NSString*)readFileAt:(NSString*)filePath;
//獲取某個(gè)目錄下所有文件
- (NSArray*)getAllFileAtDir:(NSString*)dirPath ;
//判斷文件是否存在
- (BOOL)fileIsExistAtPath:(NSString*)filePath ;
//計(jì)算某個(gè)文件大小
- (unsigned long long)computerFileSizeAtPath:(NSString*)filePath;
//計(jì)算整個(gè)文件夾中所有文件大小
- (unsigned long long)computerDirSizeAtPath:(NSString*)dirPath;
//刪除文件
- (BOOL)removeFileAtPath:(NSString*)filePath;
//移動(dòng)文件
- (BOOL)moveFile:(NSString*)fileName fromPath:(NSString*)fromPath toPath:(NSString*)toPath;

初始化一下NSFileManager 并獲取根路徑
主要是加了一些判斷岂座，代碼不是很精簡(jiǎn) 不要笑我太示。
