因此，将我的部分屏幕复制到粘贴板的代码可以正常工作，因为它成功地将其复制到我的相册中。但是，我希望能够将部分屏幕截图粘贴到新的 SMS 消息中。我知道它必须手动完成（长时间按住消息和粘贴），但它要么什么都不粘贴，要么没有粘贴选项（因为它将它保存为字符串）。代码的中间部分是我正在努力的部分。任何帮助都会很棒。我已将 forPasteboardType 更改为“图像”，但这也不起作用。

    //Capture part of Screen Shot
        UIGraphicsBeginImageContext(self.view.bounds.size);
        CGContextRef c = UIGraphicsGetCurrentContext();
        CGContextTranslateCTM(c, 0, 98);    //
        [self.view.layer renderInContext:c];
        UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();

    //Send Screenshot to Pasteboard    
    UIPasteboard *pasteBoard = [UIPasteboard pasteboardWithName:UIPasteboardNameGeneral create:YES];
    pasteBoard.persistent = YES;
    NSData *data = UIImagePNGRepresentation(viewImage);
    [pasteBoard setData:data forPasteboardType:(NSString *)kUTTypePNG];     

    /////// Open SMS
    MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
    if([MFMessageComposeViewController canSendText])
    {
        controller.body = @"Hello from me, paste image here -->";
        controller.recipients = [NSArray arrayWithObjects:@"123456789", nil];
        controller.messageComposeDelegate = self;
        [self presentModalViewController:controller animated:YES];
    }
    ////// End SMS
}
