ios邮件源生分享添加图片

高圆圆.jpeg

需求:邮件body中的图片是直接展现的,不是以附件形式出现的

// 初始化
 MFMailComposeViewController *mailComposeViewController = [[MFMailComposeViewController alloc]init];

1>.该图片是url类型:

NSString *emailBody = [NSString stringWithFormat:@"<p>%@</p>![](%@)",@"高圆圆",@"http://upload-images.jianshu.io/upload_images/2030619-d1af03e042fda3fc.jpg?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240"];

[mailComposeViewController setMessageBody:emailBody isHTML:YES];

2>.图片是NSData类型:

NSData *imageData = messageObject.thumImage;  //  messageObject.thumImage是nsdata类型的图片
NSString *imageSource = [NSString stringWithFormat:@"data:image/png;base64,%@",[imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength]];
NSString *email = [NSString stringWithFormat:@"<img src = \"%@\"/>",imageSource];
[mailComposeViewController setMessageBody:email isHTML:YES];

3>.图片是UIimage类型的

先通过
imageData = UIImagePNGRepresentation(messageObject.thumImage);
或者
imageData = UIImageJPEGRepresentation(image,1.0)
转换成NSData类型去实现

如果想以依附件形式分享文件(图片,文件等都可以)

[mailComposeViewController addAttachmentData:imagedatat mimeType:@"png" fileName:@"hallDataBanner@2x"];
