IOS：拍照并通过UIActivityView发送电子邮件

Question

在应用程序本身拍照后，我想通过电子邮件发送此照片（附上）UIActivityView。

以下是我正在使用的代码。它在项目中拍摄了一张照片，但我需要获取（发送）我刚开发的应用程序所拍摄的照片。

(IBAction)shareImage:(id)sender
{
    UIImage *image = [***UIImage imageNamed:@"zzzzz.png"***];
    NSString *message = @"yyyyyyy";
    NSArray *postItens = @[image, message];
    UIActivityViewController *objVC = [[UIActivityViewController alloc]
                                       initWithActivityItems:postItens applicationActivities:nil];
    [self presentViewController:objVC animated:YES completion:nil];
}

这是我选择图片的代码：

(void) useCamera{if ([UIImagePickerController isSourceTypeAvailable:
         UIImagePickerControllerSourceTypeCamera])
{
    UIImagePickerController *imagePicker =[[UIImagePickerController alloc] init];
    imagePicker.delegate = self;imagePicker.sourceType =UIImagePickerControllerSourceTypeCamera;
    imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage,nil];
    imagePicker.allowsEditing = YES;
    [self presentModalViewController:imagePicker
                                animated:YES];
    newMedia = YES;
}


-(void)imagePickerController:(UIImagePickerController *) pickerdidFinishPickingMediaWithInfo:(NSDictionary *)info
{ 
    NSString *mediaType = [infoobjectForKey:UIImagePickerControllerMediaType];
    [self dismissModalViewControllerAnimated:YES];
    if ([mediaType isEqualToString:(NSString *)kUTTypeImage])
    {
        UIImage *image = [infoobjectForKey:UIImagePickerControllerOriginalImage];
        imageView.image = image;
 if(newMedia)UIImageWriteToSavedPhotosAlbum(image,self,@selector(image:finishedSavingWithError:contextInfo:),nil);}else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie]){// Code here to support video if enabled}}
