Question

I have a text view and I need to add image in text view.The text view idea can be assume as text and image and after image text and so on.I can add image on text view but my problem is when I again edit my text view ,the text go behind the image.What I want is suppose if the image is below my cursor position and I am editing the text so my image should also be shift front or back.Please help me how can I achieve the functionality of shifting image on editing text.My app deployment target is 5.0 so we can include the new features provided in ios 5.0.

In the image it is shown how on editing the text the text go behind the image view.That is why I need to shift my image view.

Please Please help me.I am stuck here.

Dude Use my code…

- (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, 320.0f, 20);//use YourImageView. height and width 
    YourImageView.frame=frame;
}
return YES;
}

//imgSwipe2 is my UIImgaeView you can use your imageview. May Be i forgot to release some object and i am sure that you can handle but it's working fine,

-(void)textViewDidChangeSelection:(UITextView *)textView
 {
  NSRange range = textView.selectedRange;
if(range.location<textView.text.length)
{
    NSString * firstHalfString = [txtView.text substringToIndex:range.location]; 

    CGSize s = [firstHalfString sizeWithFont:[UIFont systemFontOfSize:15] 
                           constrainedToSize:CGSizeMake(self.view.bounds.size.width - 40, MAXFLOAT)  // - 40 For cell padding
                               lineBreakMode:UILineBreakModeWordWrap];   

    if(s.height<imgSwipe2.frame.origin.y)
    {
        // You can use this code any number of image

        imgSwipe2.frame = CGRectMake(imgSwipe2.frame.origin.x, s.height, imgSwipe2.frame.size.width, imgSwipe2.frame.size.height);  


    }
    else
    {
        // Do what ever you want to do

        NSString * firstString1 = textView.text;                
        CGSize s = [firstString1 sizeWithFont:[UIFont systemFontOfSize:15] 
                            constrainedToSize:CGSizeMake(self.view.bounds.size.width - 40, MAXFLOAT)  // - 40 For cell padding
                                lineBreakMode:UILineBreakModeWordWrap];   
        imgSwipe2.frame = CGRectMake(imgSwipe2.frame.origin.x, s.height, imgSwipe2.frame.size.width, imgSwipe2.frame.size.height);


    }   
  }
}

Hope,this will help you…Enjoy…
