Question

美好的一天！我只想问一下如何将编程截图图像附加到iMessage？

这是我使用的截图代码

UIGraphicsBeginImageContext(self.view.bounds.size);
 [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
 UIImage *screenshotimage = UIGraphicsGetImageFromCurrentImageContext();
 UIGraphicsEndImageContext();
 UIImageWriteToSavedPhotosAlbum(screenshotimage, nil, nil, nil);

现在我有了这段代码，以编程方式为任何指定的号码或电子邮件创建iMessage，

MFMessageComposeViewController *textComposer = [[MFMessageComposeViewController alloc]init];
 [textComposer setMessageComposeDelegate:self];
  NSString *messagebody = [NSString stringWithFormat:@"Here's my message"];

     if ([MFMessageComposeViewController canSendText]) {
         [textComposer setRecipients: [NSArray arrayWithObjects:@"sample@email.com", nil]];
         [textComposer setBody:messagebody];
         [self presentViewController:textComposer animated:YES completion:NULL];

     } else {
         NSLog(@"Can't Open Text");
     }

现在，我试过的是这个，

UIGraphicsBeginImageContext(self.view.bounds.size);
     [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
     UIImage *screenshotimage = UIGraphicsGetImageFromCurrentImageContext();
     UIGraphicsEndImageContext();
     //UIImageWriteToSavedPhotosAlbum(screenshotimage, nil, nil, nil);

     MFMessageComposeViewController *textComposer = [[MFMessageComposeViewController alloc]init];
     [textComposer setMessageComposeDelegate:self];

     NSString *attachmentmessage = [NSString stringWithFormat:@"Here's my Screenshot %@",screenshotimage];




if ([MFMessageComposeViewController canSendText]) {
     [textComposer setRecipients: [NSArray arrayWithObjects:@"sample@email.com", nil]];
     [textComposer setBody:attachmentmessage];
    [self presentViewController:textComposer animated:YES completion:NULL];

 } else {
     NSLog(@"Can't Open Text");
 }

是的，它会自动创建预设消息，但Image i＆ve; screenshot屏幕截图不在附件中？这是我得到的示例预设消息

你需要这个

NSString *attachmentmessage = @"Here's my Screenshot"];


if ([MFMessageComposeViewController canSendText]) {
    [textComposer setRecipients: [NSArray arrayWithObjects:@"sample@email.com", nil]];
    [textComposer setBody:attachmentmessage];
    [textComposer addAttachmentData:UIImageJPEGRepresentation(screenshotimage,1.0) typeIdentifier:@"public.data" filename:@"image.png"];
    [self presentViewController:textComposer animated:YES completion:NULL];

iOS截屏并自动附加到iMessage
