获取文件夹总大小

+ (long long)getTotleFileSize{    NSFileManager* fileManager=[NSFileManager defaultManager];    NSDirectoryEnumerator * enumerator = [fileManager enumeratorAtPath:NSHomeDirectory()];    long long totalSize = 0;    NSString * aPath = @"";    while (aPath = [enumerator nextObject]) {        NSString * realPath = [NSHomeDirectory() stringByAppendingPathComponent:aPath];                NSDictionary * dic = [fileManager attributesOfItemAtPath:realPath error:nil];        totalSize += [dic[@"NSFileSize"] longLongValue];    }    NSLog(@"------- 总大小为:  %.2f",totalSize/1000.0/1000.0);    totalSize = totalSize/1000.0/1000.0;        return totalSize;}

获取某个文件夹大小

+(float)fileSizeForDir:(NSString*)path{    NSFileManager *fileManager = [[NSFileManager alloc] init];    float size =0;    NSArray* array = [fileManager contentsOfDirectoryAtPath:path error:nil];    for(int i = 0; i<[array count]; i++)    {        NSString *fullPath = [path stringByAppendingPathComponent:[array objectAtIndex:i]];        BOOL isDir;        if ( !([fileManager fileExistsAtPath:fullPath isDirectory:&isDir] && isDir) )        {            NSDictionary *fileAttributeDic=[fileManager attributesOfItemAtPath:fullPath error:nil];            size+= fileAttributeDic.fileSize/ 1024.0/1024.0;        }        else        {            [self fileSizeForDir:fullPath];        }    }    return size;}

  获取某文件Documents下的路径

+ (NSString*)GetPath:(NSString*)fileName{    NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);    NSString* documentsDirectory = [paths objectAtIndex:0];    NSString* fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName];    return fullPathToFile;}

删除沙盒里对应文件

+ (void)deleteFileWithImageName:(NSString*)str {    NSFileManager* fileManager=[NSFileManager defaultManager];    //    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);    //    NSString *uniquePath=[[paths objectAtIndex:0] stringByAppendingPathComponent:str];    NSString *uniquePath=[self GetPath:str];    BOOL Have=[[NSFileManager defaultManager] fileExistsAtPath:uniquePath];    if (!Have) {        NSLog(@"no  have");        return ;    }else {        NSLog(@" have");        BOOL Delet= [fileManager removeItemAtPath:uniquePath error:nil];        if (Delet) {            NSLog(@"delete success");        }else {            NSLog(@"delete failed");        }    }}
