Extract first word from UITextView
In my app I have a UILabel which is the title and a UITextView which is the description and I want the title UILabel t开发者_运维知识库o be the first word typed into the UITextView. Does anyone know how to do this?
If I understand well your problem, this code might do the trick:
- (void)textViewDidChange:(UITextView *)textView
{
NSString *text = _textView.text;
NSArray *elements = [text componentsSeparatedByString:@" "];
if ([elements count] > 0)
{
_label.text = [elements objectAtIndex:0];
}
}
