//不论是创建还是写入只需调用此段代码即可 如果文件未创建 会进行创建操作
- (void)writeToFileWithTxt:(NSString *)string{
    dispatch_async(dispatch_get_global_queue(0, 0), ^{
        @synchronized (self) {
            //获取沙盒路径
            NSArray *paths  = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
            //获取文件路径
            NSString *theFilePath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"testLogs2.text"];
            //创建文件管理器
            NSFileManager *fileManager = [NSFileManager defaultManager];
            //如果文件不存在 创建文件
            if(![fileManager fileExistsAtPath:theFilePath]){
                NSString *str = @"日志开始记录
";
                [str writeToFile:theFilePath atomically:YES encoding:NSUTF8StringEncoding error:nil];
            }
            NSLog(@"所写内容=%@",string);
            NSFileHandle *fileHandle = [NSFileHandle fileHandleForUpdatingAtPath:theFilePath];
            [fileHandle seekToEndOfFile];  //将节点跳到文件的末尾
            NSData* stringData  = [[NSString stringWithFormat:@"%@
",string] dataUsingEncoding:NSUTF8StringEncoding];
            [fileHandle writeData:stringData]; //追加写入数据
            [fileHandle closeFile];
        }
    });
}
 
 
 
 
 
 
 

自己是程序员,干嘛不自己写代码完成?下载工具还不一定管用!具体解决方案如下:

1,获得内容

NSArray *dictionary = [NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"DiseaseListData" ofType:@"plist"]];

2,保存文件格式和路径
NSString *documents = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES).lastObject;
NSString *filePath = [documents stringByAppendingString:@"/lala.txt"];

3,把内容保存到txt文件
[dictionary writeToFile:filePath atomically:YES];
NSLog(@"%@",[NSBundle mainBundle].resourcePath);
