ios - 當InApp郵件命令被調用時，應用程序崩潰

當我通過UIActionSheet按鈕完成Message Compose表單時，出現以下錯誤。對不起，這些對我來說意義不大 - 仍然在學習:-)ios - 當InApp郵件命令被調用時，應用程序崩潰

請問誰能幫忙？

這是問題出現的根源。

有些代碼對我們很有幫助。 – Akshay

嗨，我添加了整個方法，我希望它的幫助 –

//刪除郵件視圖 [self dismissModalViewControllerAnimated：YES]; 刪除此行，然後再試一次，因爲郵件視圖仍然沒有加載，所以你正在解僱哪個模態視圖 – Sumanth

正確答案是在presentModalViewController方法後面刪除

[self dismissModalViewControllerAnimated:YES]

。

您正在崩潰，因爲您在呈現模型視圖控制器後立即關閉模型視圖控制器，並嘗試在回調委託中再次解除模式視圖控制器（已解除分配）。

您可以在我的文章中閱讀關於如何發送應用內電子郵件。
