推荐答案

您还可以执行以下操作:

You can also do something like:

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

您可以使用此方法的组合来组合CSV(将列名的一个数组的输出追加到值的一个数组等).

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，您必须要小心在已包含逗号的值两边加上引号，然后再对值中的所有引号进行转义.

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.
