UITextView doesn't show until it is scrolled

Question

I am using a UITextView to display the text from a xml.I parsed the xml and stored the text in a NSArray and from there i am adding it to a UITextview in my code.

problem: When i run the code the textview shows as empty or with partial text,and when i try to scroll the textview the whole text is getting displayed.

I added the UITextview to a UIView.

i found it strange and googled it but could not find many answers which helps me. Can someone reply me to solve the issue

TNQ

Answer 1

Found a simple SOLUTION

Had the same problem. When you put text into a UITextView which is not visible, it doesn't draw the text.

I had my UITextView off screen and animated it in like this:

    [UIView animateWithDuration:0.3 delay:0.0 options:UIViewAnimationCurveEaseOut animations:^{
    self.contentView.center = CGPointMake(self.contentView.center.x + move * (self.contentView.frame.size.width /2), self.contentView.center.y);
    self.textView.frame = self.textView.frame; // <<<--- ADD THIS LINE
    } completion:^(BOOL finished) {
    if (finished) {
    }
}];

When you re-set the textview's frame, it re-draws it's text. So all you need to do is add the line I marked above before your UITextView comes on screen.

Cheers

UITextView inherits from UIScrollView, so just scroll it.

[detailsTextView setContentOffset:CGPointMake(0, 1) animated:YES];

Answer 3

i solved the issue by clearing the textview and added the text to the textview again,i dont know the exact funda but my issue is solved. in my case: i am changing the frame of the textview from outside to the view on click of a button.while the button is clicked the textview is not showing content and on scroll it shows.

i solved, by deleting the text from textview and re entering the text on clicking the button.
