问题 I'm trying to include an image in the body of an HTML email sent from an iPad. It seems impossible. I have tried to use the CID approach, but it seems that in iOS it is not possible to get/set the CID of attachments. I've also tried to embed the image with src="data:image/png;base64, blahblahblah" . When you compose the mail it seems to work, but nothing appears when the mail is received. Any ideas? More Detail : We are not looking for a solution where the JPEG/PNG is attached at the bottom

问题 I want to customize the MFMailComposeViewController such that it has my custom images/buttons instead of the default "cancel" and "send" buttons. I tried googling for an answer but couldn't find anything that could help me. Any help is really appreciated. Thanks in advance.. 回答1: You can't change MFMailComposeViewController. Quoting the documentation: Important: The mail composition interface itself is not customizable and must not be modified by your application. 来源： https://stackoverflow

问题 I have an app which uses MFMailComposeViewController to send documents through email. I read somewhere that I need to enable at least one email so that the method [MFMailComposeViewController canSendEmail] will return YES and email the document. However, whenever I tap the email button, all it does is return to the previous view. I checked the code and [MFMailComposeViewController canSendEmail] returns NO. Can anyone tell me why is this happening? Here is the code: - (void)sendEmail { if (

问题 No matter what I seem to try, in the email screen that comes up when a user chooses to email a link (it's a MFMailComposeViewController ) the buttons are always the default blue.

问题 I'm attaching an animated GIF to an email to be sent with MFMailComposeViewController. If the GIF is of sufficient size the MFMailComposeViewController will ask the user whether they want to resize it to a smaller size. Unfortunately, the animation will not be preserved in the resized image. How do I either forbid MFMailComposeViewController to resize the image or make it preserve the animation? 回答1: There’s no built-in API to do this, but one option is to compress the animated GIF into a ZIP
