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");
        }
    }
}
