UITextView number of lines when not showing full text (ios7)

Question

I have a UITextView that is not showing all the text in it so you need to scroll to read more. i would like to get the number of lines in the UITextView . I tried to find how but all i could find is only if you show all the text to get the number of lines.

autoLayout is on.

my code look like this:

CGRect textViewFrame = CGRectMake(20.0f, 20.0f, 280.0f, 124.0f);
UITextView *textView = [[UITextView alloc] initWithFrame:textViewFrame];
textView.returnKeyType = UIReturnKeyDone;
textView.delegate = self;
[self.view addSubview:textView];
[self contentSizeRectForTextView:textView];
textView.text=@"very long text";

i have tried:

UIFont *font = [UIFont boldSystemFontOfSize:11.0];
CGSize size = [textView.text sizeWithFont:font
                        constrainedToSize:textView.frame.size
                            lineBreakMode:NSLineBreakByWordWrapping];
float numberOfLines = size.height / font.lineHeight;
NSLog(@"%f", numberOfLines);

but it gives only the number of lines showed as well as:

float rows = round( (textView.contentSize.height - textView.textContainerInset.top - textView.textContainerInset.bottom) / textView.font.lineHeight );

Thanks in advance

Answer 1

try this!

int numLines = textview.contentSize.height / textview.font.lineHeight;

re-adjust frame:

CGFloat fixedWidth = textView.frame.size.width;
CGSize newSize = [textView sizeThatFits:CGSizeMake(fixedWidth, MAXFLOAT)];
CGRect newFrame = textView.frame;
newFrame.size = CGSizeMake(fmaxf(newSize.width, fixedWidth), newSize.height);
textView.frame = newFrame;

textview.scrollEnabled = NO;

You can use UIScrollView and add UITextView as subview. In this case scroll will change size according to text inside UITextView
