Question

I’m using a label to display the string result of function. However I have a class variable that stores the previous result and I need to update that variable in different ways depending on different conditions. The code I wrote is

    if(displayPassword.text == @"Memorable")
    {
        prevpass = [newPassword returnPassword];
    }
    else 
    {
        prevpass = displayPassword.text;
    }

However it always jumps to the else as it seems to show under debugging that displayPassword.text is always empty depsite it showing a value.

You can only use == to compare scalar values. A string is an object. You need to use the isEqual: or isEqualToString: method instead.

if([displayPassword.text isEqualToString:@"Memorable"])  {
