調用經過幾次電子郵件方式，將有上崩潰MFMailComposeViewController爲iPad

[MFSearchResultsViewController哈希]：消息發送到釋放實例或者
[MFMailComposeViewController哈希]：發送到釋放實例的消息

崩潰。

正如你所想的那樣，MFSearchResultsViewController函數是什麼。

是否可以解決問題，請幫我一下。

您必須爲郵件控制器設置Degate。如果您將代表設置爲「自我」，請確保「自我」具有<MFMailComposeViewControllerDelegate>。如果所有這些都無法使其工作，請確保您沒有撥打presentModalViewController兩次。
