NXOperationManager

多線程異步處理數據

FileCacheManager使用說明

• 文件數據少則幾十k大則上百兆，文件緩存處理不好嚴重影響用戶體驗
• FileCacheManager能夠異步處理多個文件而不影響界面交互
  

FileCacheManager

• FileCacheManager
• FileCacheOperation
• FileCacheOperationManager

建立FileCacheModel對象

NSString * content = @"定風波 蘇軾\n（三月七日沙湖道中遇雨。雨具先去，同行皆狼狽，余獨不覺。已而遂晴，故作此 ）。\n莫聽穿林打葉聲，何妨吟嘯且徐行。竹杖芒鞋輕勝馬，誰怕？ 一蓑煙雨任平生。\n料峭春風吹酒醒，微冷，山頭斜照卻相迎。回首向來蕭瑟處，歸去，也無風雨也無晴。";
FileCacheModel * fileCacheModel = [[FileCacheModel alloc] init];
fileCacheModel.fileName = @"定風波.蘇軾";
fileCacheModel.fileData = [content dataUsingEncoding:NSUTF8StringEncoding];
fileCacheModel.fileType = @"txt";

注：文件名、數據不能為空

建立FileCacheOperationManager對象

FileCacheOperationManager * fileCacheOperationManager =[[FileCacheOperationManager alloc] initWithSearchPathModel:NXSearchPathModelCache rootFilePath:@"宋詞.蘇軾"];
[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：可以進行二次封裝，類似于AFNetworking;rootFilePath是存儲目錄路徑，多層次包含用‘.’隔開，例如本例子中‘宋詞.蘇軾’轉化為存儲目錄為/宋詞/蘇軾

二次封裝說明

• SongCiDataCacheConfiguration:來封裝存儲模式、根目錄
• SongCiCacheOperationManager:繼承于FileCacheOperationManager，單例
  注：這里用一個例子來說明二次封裝

[[SongCiCacheOperationManager sharedSongciCacheOperationManager] cacheFileWith:fileCacheModel success:^(FileCacheOperation *operation, NSString *filePath) {
    NSLog(@"二次封裝----%@",filePath);
} failure:^(FileCacheOperation *operation, NSString *errorInfo) {
    NSLog(@"二次封裝----%@",errorInfo);
}];
