如何将数组转换为字符串？

Question

如果我将它用于NSDictionary，我如何将数组转换为字符串？字典将用作JSON中的参数。

这是我的代码。

'_emailsInApi = [[DBManager getSharedInstance]arrayOfEmails];

NSDictionary *params =@{@"api_key":@"APIKEY",@"action":@"get-status",@"email":[[[DBManager getInstance]Emails]description]};'

这是NSLog

array: (
    "<Inquiry: 0x10d14cce0>",
    "<Inquiry: 0x1092db900>",
    "<Inquiry: 0x1092db9b0>",
    "<Inquiry: 0x10d148610>",
    "<Inquiry: 0x10d148690>",
    "<Inquiry: 0x10d148710>",
    "<Inquiry: 0x10d176fb0>",
    "<Inquiry: 0x10d1770a0>",
    "<Inquiry: 0x10d1d6610>",
    "<Inquiry: 0x10d1d66c0>",
    "<Inquiry: 0x1092d93f0>",
    "<Inquiry: 0x1092d32c0>",
    "<Inquiry: 0x1092d3340>",
    "<Inquiry: 0x1092d33c0>",
    "<Inquiry: 0x10d1482a0>"
)

这导致API返回某些电子邮件无效。

我的问题是：如何将_emailsInApi（数组）转换为字符串。这样它的价值就像myemail@email.com，secondemail @email.com .....

感谢您的帮助。
