多线程异步处理数据
FileCacheManager使用说明
- 文件数据少则几十k大则上百兆，文件缓存处理不好严重影响用户体验
- FileCacheManager能够异步处理多个文件而不影响界面交互
FileCacheManager
- FileCacheManager
- FileCacheOperation
- FileCacheOperationManager
建立FileCacheModel对象
NSString * content = @"定风波 苏轼\n（三月七日沙湖道中遇雨。雨具先去，同行皆狼狈，余独不觉。已而遂晴，故作此 ）。\n莫听穿林打叶声，何妨吟啸且徐行。竹杖芒鞋轻胜马，谁怕？ 一蓑烟雨任平生。\n料峭春风吹酒醒，微冷，山头斜照却相迎。回首向来萧瑟处，归去，也无风雨也无晴。"; FileCacheModel * fileCacheModel = [[FileCacheModel alloc] init]; fileCacheModel.fileName = @"定风波.苏轼"; fileCacheModel.fileData = [content dataUsingEncoding:NSUTF8StringEncoding]; fileCacheModel.fileType = @"txt";
注：文件名、数据不能为空
建立FileCacheOperationManager对象
FileCacheOperationManager * fileCacheOperationManager =[[FileCacheOperationManager alloc] initWithSearchPathModel:NXSearchPathModelCache rootFilePath:@"宋词.苏轼"]; [fileCacheOperationManager cacheFileWith:fileCacheModel success:^(FileCacheOperation *operation, NSString *filePath) { NSLog(@"%@",filePath); dispatch_async(dispatch_get_main_queue(), ^{ _filePathLabel.text = filePath; }); } failure:^(FileCacheOperation *operation, NSString *errorInfo) { NSLog(@"%@",errorInfo); dispatch_async(dispatch_get_main_queue(), ^{ _filePathLabel.text = errorInfo; }); }];注：可以进行二次封装，类似于AFNetworking;rootFilePath是存储目录路径，多层次包含用‘.’隔开，例如本例子中‘宋词.苏轼’转化为存储目录为/宋词/苏轼
二次封装说明
- SongCiDataCacheConfiguration:来封装存储模式、根目录
- SongCiCacheOperationManager:继承于FileCacheOperationManager，单例
注：这里用一个例子来说明二次封装
[[SongCiCacheOperationManager sharedSongciCacheOperationManager] cacheFileWith:fileCacheModel success:^(FileCacheOperation *operation, NSString *filePath) { NSLog(@"二次封装----%@",filePath); } failure:^(FileCacheOperation *operation, NSString *errorInfo) { NSLog(@"二次封装----%@",errorInfo); }];
