Text Field (Newbie question)

VladislavZagorodnyuk

Hi guys,i have next code, where answerText is UITextField

 if (answerText.text == @1)      {         NSLog(@YES);     }     else NSLog(@NO);

this code always returns NO when i type in textField "1" (in iOS Simulator),it returns YES only when i type in Xcode answerText.text = @1,why?

Hi.

You're comparing pointers to two strings. Remember, @1 is just a shortcut to create a brand new NSString object containing the single character '1'. Both strings *look* the same, but they are separate objects.

Instead use isEqualToString: (see Apple's documentation).

if ([answerText.text isEqualToString:@1]) {     NSLog(@YES); } else NSLog(@NO);

Cheers,

Nick.

UPDATE: I just happened across this road map from Apple, and this page seems particularly relevant.
