IOS Character Counter

Cory Rylan

- less than a minute

This following example is a small character counter that can keep track of the number of characters in a text view that needs to be limited to a maximum amount of characters.

//Only check if text field has been altered
-(void)textViewDidChange:(UITextView *)textView{
//500 chars max
if([[textView text] length] > 500){
//If max reached close keypad
[textView resignFirstResponder];
//Append off extra chars
textView.text = [textView.text substringToIndex:500];
}
//Count and display amount of chars left
CounterBoxLabel.text = [NSString stringWithFormat:@"Characters left: (%i)", 500 - [[textView text] length]];
}
