考虑将特殊字符放入 .csv 文件中

发布于 2024-11-07 12:38:32 字数 609 浏览 0 评论 0原文

我正在开发应用程序，在其中我必须考虑所有特殊字符。我正在使用下面的代码，但在其中我也想考虑“空格和逗号”，但在其中，当触发空格时，它会在该位置分割并创建新的字段为它..所以朋友们有没有考虑特殊字符的解决方案。如果您有任何想法，请建议我。谢谢

   arrCsv=[[NSArray alloc]initWithObjects:@"Hello",@"Hi",@"traun  testdata",@"Hi,fine",nil];
NSArray *paths = NSSearchPathForDirectoriesInDomains

(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *fileName = [NSString stringWithFormat:@"%@/try.csv", documentsDirectory];


[[arrCsv componentsJoinedByString:@","] writeToFile:fileName atomically:YES encoding:NSUTF8StringEncoding error:NULL];

以简单的方式编写您自己的 CSV 解析例程既容易出错，又会浪费不必要的时间。我强烈建议您使用 Dave DeLong 优秀的 CHCSV 库。

如果您想使用此库，您可以按照以下方式执行操作以将两行写入文件：

NSArray *row1 = [NSArray arrayWithObjects:@"Field One", @"Field Two", @"Field, three", nil];
NSArray *row2 = [NSArray arrayWithObjects:@"Field' One", @"Field,, Two", @"Field\" three", nil];
NSArray *rows = [NSArray arrayWithObjects:row1, row2, nil];

NSError *error = nil;
[rows writeToCSVFile:@"path/to/file.csv" atomically:YES error:&error];
if (error) {
    // do something with error
}

Writing your own CSV parsing routines in a simplistic fashion is both error-prone and needlessly time-consuming. I highly recommend you use Dave DeLong's excellent CHCSV library.

If you wanted to use this library, you could do something along the following lines to write two rows to a file:

NSArray *row1 = [NSArray arrayWithObjects:@"Field One", @"Field Two", @"Field, three", nil];
NSArray *row2 = [NSArray arrayWithObjects:@"Field' One", @"Field,, Two", @"Field\" three", nil];
NSArray *rows = [NSArray arrayWithObjects:row1, row2, nil];

NSError *error = nil;
[rows writeToCSVFile:@"path/to/file.csv" atomically:YES error:&error];
if (error) {
    // do something with error
}
