MFMailComposer發送附件圖像大小增加

Question

我正在使用MFMailComposer使用此代碼發送image.m

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
        if (picker !=nil) {
            picker.mailComposeDelegate = self;
            NSString *msgTitle;
            [picker setToRecipients:[NSArray arrayWithObjects:@"", nil]];
            [picker setSubject:msgTitle];
            [picker addAttachmentData:UIImagePNGRepresentation(imageView.image) mimeType:@"image/png" fileName:@"img"];
            [self presentModalViewController:picker animated:YES];

如果我的圖像大小是MFMailModalView中的500kb，圖像大小將顯示2MB。

images是big.i僅以與我的代碼相同的大小發送圖像。

Answer 1

NSData *UIImageJPEGRepresentation(UIImage *image, CGFloat compressionQuality)

//Replace this snippet to your code
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; 
if (picker !=nil) { 
   picker.mailComposeDelegate = self; 
   NSString *msgTitle;
   [picker setToRecipients:[NSArray arrayWithObjects:@"", nil]]; 
   [picker setSubject:msgTitle];    
   [picker addAttachmentData:UIImageJPEGRepresentation(imageView.image,0.5) mimeType:@"image/png" fileName:@"img"]; 
   [self presentModalViewController:picker animated:YES];

該功能將幫助您壓縮圖像尺寸。
