UITextView Text size is auto resized while using the NSAttributedString

In the UITextView text,

before highlight the text, its shown the text size as 16. (in the first image)

after the using the NSAttributedString to highlight. highlighted text only show that same size(16) remaining strings show lesser than that the original size (second .

this problem only in the iPod and iPhone deceive . iPad is shown correct format.

enter image description here

code to highlight the UITextView Text

 NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObject:[UIFont fontWithName:@"Arial" size:currentTextSize] forKey:NSFontAttributeName];

    NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:txtview4disp.text];

 int startind=[[dict objectForKey:@"BeginIndexPos"]integerValue];
        int endind=[[dict objectForKey:@"EndIndexPos"]integerValue];
        NSRange rang;
        if (startind>=STARTINDEX&&startind<=ENDINDEX) {
            if (endind>ENDINDEX) {
                int endind2=endind-ENDINDEX;
                rang=NSMakeRange(startind-STARTINDEX, (endind-startind)-endind2);   
            }
            else
                rang=NSMakeRange(startind-STARTINDEX, endind-startind);


        [attrString addAttributes:attrsDictionary range:rang];

        [attrString addAttribute:NSBackgroundColorAttributeName value:[UIColor yellowColor] range:rang];

   txtview4disp.attributedText=attrString;

It looks like you skipped the original attributes of your UITextView. Try replacing this line:

NSMutableAttributedString *attrString =
[[NSMutableAttributedString alloc] initWithString:txtview4disp.text];

with following:

NSMutableAttributedString *attrString =
[[NSMutableAttributedString alloc] initWithAttributedString:txtview4disp.attributedText];
