我使用下面的UIImagePickerController委托方法从 iphone 捕获了图像。 

    - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    self.myImageView.image = image;  
    //    [self performSelector:@selector(emailButtonPressed:) withObject:image afterDelay:1.0];
     [self dismissModalViewControllerAnimated:YES];  
}

请参阅上面的emailButtonPressed方法，它是由 调用的self。我想在按钮操作中调用它。我为emailButtonPressed.

- (void)emailButtonPressed:(UIImage *)image
{  
        MFMailComposeViewController *mailview=[[MFMailComposeViewController alloc]init];      mailview.navigationBar.tintColor=[UIColor colorWithRed:55/255.0 green:190/255.0 blue:55/255.0 alpha:1];  
        mailview.mailComposeDelegate=self;  
        // NSMutableString *subject=[NSMutableString stringWithFormat:@"%@",@"Testing"];  
        [mailview setSubject:@"Picture from my iPhone!"];  
        //   NSString *email_new=@"";  
        [mailview setMessageBody:@"Description" isHTML:NO];  

        NSData *imageData = UIImagePNGRepresentation(image);  

        [mailview addAttachmentData:imageData mimeType:@"image/png" fileName:@"ImageName"];  
        [self presentModalViewController:mailview animated:YES];  
}

抱歉我的代码中的任何错误。

修改你的emailButtonPressed方法如下，

- (void)emailButtonPressed //removed the param
{  
        UIImage *image = self.myimageview.image; //or set some other param as image = self.image; whichever you set in picker delegate method
        MFMailComposeViewController *mailview=[[MFMailComposeViewController alloc]init];      mailview.navigationBar.tintColor=[UIColor colorWithRed:55/255.0 green:190/255.0 blue:55/255.0 alpha:1];  
        mailview.mailComposeDelegate=self;  
        // NSMutableString *subject=[NSMutableString stringWithFormat:@"%@",@"Testing"];  
        [mailview setSubject:@"Picture from my iPhone!"];  
        //   NSString *email_new=@"";  
        [mailview setMessageBody:@"Description" isHTML:NO];  

        NSData *imageData = UIImagePNGRepresentation(image);  

        [mailview addAttachmentData:imageData mimeType:@"image/png" fileName:@"ImageName"];  
        [self presentModalViewController:mailview animated:YES];  
}

保持这种方法不变，

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    self.myImageView.image = image;  //instead of this, you can create an @property for image in .h file and assign to that also here.
    [self dismissModalViewControllerAnimated:YES];  
}

假设您已将电子邮件按钮声明为，

UIButton *emailbutton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; //or any other way

现在在该行之后立即将此方法添加为您的按钮目标，

[emailbutton addTarget:self action:@selector(emailButtonPressed) forControlEvents:UIControlEventTouchUpInside];

现在点击您在委托emailbutton中设置的任何图像都将作为附件发送。self.myimageview.imageUIImagePickerController
