Question

I want to ask a objective C question. I have a string retrieve from UITextField and I want to check the string contains the ‘@’ or not. However, when I use the following code, it has some errors, can anyone help me? Thank you.

if([inputTextField.text rangeOfString:@"%"].location != NSNotFound)
    NSLog(@"It does not contain the %@");
else
    NSLog(@"It contains the %@");

Check the syntax:

if([inputTextField.text rangeOfString:myString].location == NSNotFound)
    NSLog(@"It does not contain the %@", myString);
else
    NSLog(@"It contains the %@", myString);

As you will see, the %@ will be replaced with the content of myString.
