在ios6中的ipad中的应用程序中将图像附加到电子邮件 [英] Attaching a image to an email in an app in ipad in ios6

问题描述

我正在尝试将图像附加到电子邮件中，并将电子邮件发送到我的电子邮件地址。问题是，当我发送附有4或5张图像的电子邮件时，该应用程序将永远处理，最终被挂起并崩溃，不会发送电子邮件。一个图像正常工作。我在想，这是因为图像的大小结合在一起。 Btw，我正在使用iOS 6 ..如何限制发送的文件或图像的大小？或者可能还有其他问题？相同的应用程序正在ios5 ....

I am trying to attach images to the email and send the email to my email add. The problem is that when i send out an email with 4 or 5 images attached, the app keeps processing for ever and eventually gets hanged and crashes and doesn't send the email. It is working fine with one image. I am thinking it is because of the size of the images combined together. Btw, I am using iOS 6.. How do i restrict the size of the files or images sent? Or there might be other issues involved? The same app is working in ios5....

电子邮件发送部分与图像一起是：

The email sending portion together with image is:

for (int nCtr = 0; nCtr < [Pix count]; nCtr++) {
            UIImageView *imageV = [Pix objectAtIndex:nCtr];
            if (imageV.image) {
                NSData *imageData = UIImagePNGRepresentation(imageV.image);
                NSString *strFileName = [NSString stringWithFormat:@"MyPicture-%d.jpeg",nCtr];

                NSString *strFormat = [NSString stringWithFormat:@"image/jpeg;\r\n\tx-unix-mode=0644;\r\n\tname=\"%@\"",strFileName];
                NSString *strFormat2 = [NSString stringWithFormat:@"attachment;\r\n\tfilename=\"%@\"",strFileName];
                NSDictionary *vcfPart = [NSDictionary dictionaryWithObjectsAndKeys:strFormat,kSKPSMTPPartContentTypeKey,
                                         strFormat2,kSKPSMTPPartContentDispositionKey,[imageData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];

                [images addObject:vcfPart];
            }

推荐答案

只需将其从PNG格式更改到JPEG格式。

Just change it from PNG format to JPEG format.

for (int nCtr = 0; nCtr < [arrPix count]; nCtr++) {
            UIImageView *imageV = [arrPix objectAtIndex:nCtr];
            if (imageV.image) {
                NSData *imageData = UIImageJPEGRepresentation(imageV.image, 0.9);
                NSString *strFileName = [NSString stringWithFormat:@"MyPicture-%d.jpeg",nCtr];

                NSString *strFormat = [NSString stringWithFormat:@"image/jpeg;\r\n\tx-unix-mode=0644;\r\n\tname=\"%@\"",strFileName];
                NSString *strFormat2 = [NSString stringWithFormat:@"attachment;\r\n\tfilename=\"%@\"",strFileName];
                NSDictionary *vcfPart = [NSDictionary dictionaryWithObjectsAndKeys:strFormat,kSKPSMTPPartContentTypeKey,
                                         strFormat2,kSKPSMTPPartContentDispositionKey,[imageData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];

                [parts addObject:vcfPart];
            }
        }

看起来ios6限制了图像的大小。 ..最好压缩图像...

It seems that ios6 limits the size of the images...Hence it is better to compress the image...
