多行自动调整大小的UITextView

Question

I want to insert a couple of strings to my UITextView so they are displayed vertically

Tried this code:

NSMutableString* examinationsString = [NSMutableString string];

for (NSString * examination in examinationsArray)
{
    [examinationsString appendString:[NSString stringWithFormat:@"%@, %s ",examination, "\n"]];
}

return examinationsString;

I had changed UITextView Lines property to 5 but still getting all in one line, separated with "/"

What am I doing wrong?

I'd also want the UITextView to stretch if there are more than 1 line, if it's not achieved automatically of course

Answer 1

Please try following code:

NSMutableString* examinationsString = [NSMutableString string];

for (NSString * examination in examinationsArray)
{
    [examinationsString appendString:[NSString stringWithFormat:@"%@,\n",examination]];
}
return examinationsString;

Now to resize the UITextView as per the view's contentSize :

CGRect frame = _textView.frame;
frame.size.height = _textView.contentSize.height;
_textView.frame = frame;
