Objective-C constants: NSString comparison using ==?

i have a textfiela nd label and want the label to display certain text when text is in the textfield here is what i have so far

- (IBAction)Button {
if (Textfield1.text = @"A") {
    int text = arc4random() % 3;
    switch (text) {
        case 0:
            Label1.text = @"Red";
            break;
        case 1:
            Label1.text = @"Blue";
            break;
        case 2:
            Label1.text = @"Green";
            break;
        case 3:
            Label1.text = @"Yellow";
            break;

        default:
            break;
    }
}

}

all that happens is if prints the letter a in the textfield

any ideas?

You shouldn’t compare directly with == between NSObjects (and currently you’re assigning and not comparing, by using one equal-sign instead of two). Instead try the following:

if ([Textfield1.text isEqualToString:@"A"]) {
