Get word from long tap in a word of UITextView

Question

Now I already detect long tap in UITextView

    - (void)viewDidLoad
    {
         [super viewDidLoad];
         UILongPressGestureRecognizer *LongPressgest         


        

Answer 1

This function will return the word at a given position in an UITextView.

+(NSString*)getWordAtPosition:(CGPoint)pos inTextView:(UITextView*)_tv
{
    //eliminate scroll offset
    pos.y += _tv.contentOffset.y;

    //get location in text from textposition at point
    UITextPosition *tapPos = [_tv closestPositionToPoint:pos];

    //fetch the word at this position (or nil, if not available)
    UITextRange * wr = [_tv.tokenizer rangeEnclosingPosition:tapPos withGranularity:UITextGranularityWord inDirection:UITextLayoutDirectionRight];

    return [_tv textInRange:wr];
}
