// 文件存放目录
            NSString *pngDir = [NSHomeDirectory()stringByAppendingPathComponent:@"Documents"];
            NSFileManager *fileMgr = [NSFileManagerdefaultManager];
            NSString *FileDir = [NSStringstringWithFormat:@"%@/AnnexFiles", pngDir];
            NSError *err;
            [fileMgr createDirectoryAtPath:FileDirwithIntermediateDirectories:YES attributes:nil error:&err];
            NSString *FileFullPath = [FileDirstringByAppendingPathComponent:[DBTopicAnnexData Name]];
            BOOL bRet = [fileMgrfileExistsAtPath:FileFullPath];
            if (bRet) {
                // 
                NSError *err;
                [fileMgr removeItemAtPath:FileFullPatherror:&err];
            }

上述方法过于复杂receipt.filePath 是本地文件的存储路径
NSLog(@"receipt.filePath==%@",receipt.filePath);
        NSFileManager *fileManager = [NSFileManager defaultManager];
        BOOL fileExists = [fileManager fileExistsAtPath:receipt.filePath];
        if (fileExists) {

            NSError *err;
            [fileManager removeItemAtPath:receipt.filePath error:&err];
        }


或者// 清除本地配置数据
            NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
            NSString *documentsDirectory = [pathsobjectAtIndex:0];

 NSFileManager *fileMgr = [NSFileManager defaultManager];
            NSString *MapLayerDataPath = [documentsDirectorystringByAppendingPathComponent:@"DBMapLayerData.xml"];
            BOOL bRet = [fileMgrfileExistsAtPath:MapLayerDataPath];
            if (bRet) {
                // 
                NSError *err;
                [fileMgr removeItemAtPath:MapLayerDataPatherror:&err];
            }



ios 下创建，删除文件夹的方法2  

创建文件夹： NSString *imageDir = [NSString stringWithFormat:@"%@/Caches/%@",NSHomeDirectory(), dirName];
 BOOL isDir = NO;
 NSFileManager *fileManager = [NSFileManager defaultManager];
 BOOL existed = [fileManager fileExistsAtPath:imageDir isDirectory:&isDir];
 if ( !(isDir == YES && existed == YES) )
 {
 [fileManager createDirectoryAtPath:imageDir withIntermediateDirectories:YES attributes:nil error:nil];
 }

删除文件夹及文件级内的文件：
 NSString *imageDir = [NSString stringWithFormat:@"%@/Caches/%@",NSHomeDirectory(), dirName];
 NSFileManager *fileManager = [NSFileManager defaultManager];
 [fileManager removeItemAtPath:imageDir error:nil];
