Question

I want numeric keypad which automatically convert the value of textbox into decimal format.for example user types 10 it automatically convert .10

Answer 1

Try the following:

NSString * userInput = textBox.text;
textBox.text = [NSString stringWithFormat:@".%@", userInput];

If you need the value as an integer for other use, try:

int userInput = [textBox.text intValue];
textBox.text = [NSString stringWithFormat:@".%d", userInput];

Also, if you need to know the method to do this in real-time, use:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string; {

Make sure to return YES so that the character gets added! Hope that Helps!
