推荐答案

您也可以执行以下操作：

You can also do something like:

[[array componentsJoinedByString:@","] writeToFile:@"components.csv" atomically:YES encoding:NSUTF8StringEncoding error:NULL];

您可以使用这种方法的组合将CSV合并（将一个数组的输出

You can use combinations of this to put together a CSV (append the output of one array for the column names to one array for the values, etc).

当然，你必须小心地在已经包含逗号的值的前后加上引号，然后转义任何值的引号。

Of course, you have to be careful to put quotes around values that already contain a comma, and to then escape any quotes in the value.
