WKInterfacelabel check if truncated

I would like to check if the text in WKInterfacelabel is truncated. Since there is no text property and it seems I can not get the number of lines property that you can set in storyboard I wonder if there is any way or trick on how to achieve this!?

Thanks !

Solution

  • You can get the number of lines that a label takes to display given text using below code. 

    CGFloat labelWidth = 100.0f;
NSString *text = @"some text";
[self.label setText:text];
[self.label setWidth:labelWidth];
UIFont *font = [UIFont systemFontOfSize:12.0f];
CGRect rect = [text boundingRectWithSize:CGSizeMake(labelWidth, MAXFLOAT)
                                 options:NSStringDrawingUsesLineFragmentOrigin
                              attributes:@{NSFontAttributeName : font}
                                 context:nil];

CGFloat numOfLines =  ceil(rect.size.height / font.lineHeight);
