iOS 7 - UITextView size font to fit all text into view (no scroll)

Question

I am trying to find a non-deprecated method to size the font of a textview down so that all text fits in the textview without requiring scrolling.

The method \'sizeWithF

Answer 1

Solution 1

Your problem can be solved by simply replacing sizeWithFont: constrainedToSize: with :

boundingRectWithSize:CGSizeMake(newView.frame.size.width, FLT_MAX)
                options:NSStringDrawingUsesLineFragmentOrigin
             attributes:@{NSFontAttributeName:[UIFont fontWithName:@"Interstate" size:fontSize]}
                context:nil];

Solution 2

The sizeThatFits method can be used to address this problem like this:

while (fontSize > minSize &&  [newView sizeThatFits:(CGSizeMake(newView.frame.size.width, FLT_MAX))].height >= newView.frame.size.height ) {
    fontSize -= 1.0;
    newView.font = [tv.font fontWithSize:fontSize];
}

I hope one of these solutions solve your problem. Cheers!
