Question

I have a simple function to see if the button touched is the same as the text of a label:

- (IBAction) checkIt:(id)sender{
    UIButton *button = (UIButton *)sender;

    if(button.getText() == randomNumber.text){
        randomNumber.text = @"Nice.";
    }
    else{
        randomNumber.text = @"Try Again";
    }
}

Where “randomNumber” is a label. However, this doesn’t work. I’m a Cocoa/Objective-C beginner and I’m not sure what the proper syntax is.

I’m open to any addition information you would like/think is helpful to idiots like me. 🙂

Four buttons are mapped to this function: Cow, Pig, Frog, Sheep. The “randomNumber” label is randomized from an array of strings “Cow,Frog”…

Answer 1

if(button.getText() == randomNumber.text)

This will never work because this is not the right way to compare strings. ‘==’ only compares the memory address, the NSString method isEqualToString actually compares the strings.

Also, I would get the button text by using the property, titleLabel.text. So, I would try like this:

- (IBAction) checkIt:(id)sender{
    UIButton *button = (UIButton *)sender;

    if([button.titleLabel.text isEqualToString:randomNumber.text]){
        randomNumber.text = @"Nice.";
    }
    else{
        randomNumber.text = @"Try Again";
    }
}
