如何移動/跳光標下一行到圖像視圖中

我已經使用圖像選擇器插入在文本視圖的庫中的圖像的文本視圖與插入圖像之後，如何移動/跳光標下一行到圖像視圖中

在pickeDelegate didFinishPickingImage方法

imgview = [[UIImageView alloc] initWithImage:image]; 

      NSString *messageText = [[NSString alloc]init]; 
      messageText = messageView.text; 
      CGSize s = [messageText sizeWithFont:[UIFont systemFontOfSize:15] //define your textview font size 
           constrainedToSize:CGSizeMake(self.view.bounds.size.width - 40, MAXFLOAT) //          lineBreakMode:UILineBreakModeWordWrap]; 
      CGRect frame = CGRectMake(0.0f, s.height+10, 50, 50);//use YourImageView. height and width 
      imgview.frame=frame; 

      //[imgview setFrame:CGRectMake(0, 0, 30,30) ]; 
      [messageView addSubview:imgview];

而實現的邏輯使用跟隨着委託方法邏輯

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text; 
{ 
     if ([text isEqualToString:@"\n"]) { 

     } 
     else 
     { 
      NSString *yourstring = [[NSString alloc]init]; 
      yourstring = textView.text; 
      CGSize s = [yourstring sizeWithFont:[UIFont systemFontOfSize:15] //define your textview font size 
           constrainedToSize:CGSizeMake(self.view.bounds.size.width - 40, MAXFLOAT) // - 40 For cell padding 
            lineBreakMode:UILineBreakModeWordWrap]; 
      CGRect frame = CGRectMake(0.0f, s.height+10, 50, 50);//use YourImageView. height and width 
      imgview.frame=frame; 
     } 
     return YES; 
}

在最後文本的末尾添加圖像

但每次光標剛圖像視圖開始之前，

但i need to jump/ move the cursor after the image when ever i added the image, jus like as folows,

我requrement是用戶可在文本視圖中輸入文字，他可以在文本視圖與添加圖像然後從下一行後的圖像，他可以能夠再次輸入文字，

就像我們在這堆過流盒連接相似圖片
