I am making an iPhone app that will generate something based on quiz answers. I want the button for the answer to change the question text and sometimes the button label text.
Background Info:
- 'a' is a button
- 'questionNumber' is the question number (duh) and it is why the button will change the texts differently each time it is pressed.
Here is the code I am using:
-(IBAction) a
{
questionNumber == 0;
if(questionNumber == 0) {
question.text = @"How Much Do You Use Suppressed Weapons?";
}
questionNumber == 1;
if(questionNumber == 1) {
question.text = @"Do You Like Sleight of Hand?";
answerA.text = @"Yes";
answerB.text = @"No";
[answerC setHidden:YES];
[answerD setHidden:YES];
[answerButton3 setHidden:YES];
[answerButton4 setHidden:YES];
}
}
and this repeats for the other buttons (b,c, and d). I thought it should work, but it doesn't do the "do you like sleight of hand" question. It jus开发者_开发问答t stays at the how much do you use suppressed weapons question. Please Help! I really want to get into xcoding for the iphone.
BTW, I am not sure that the tags for this question are correct.Related Question: How can I have an IBAction that has more than two 'if' statements?
You're not assigning to questionNumber
. You're comparing.
questionNumber == 1;
That's a noop. It tests if questionNumber
is 1, and then throws away the result. You want
questionNumber = 1;
Try using a switch
statement with breaks
.
switch (questionNumber)
{
case 0:
{
question.text = @"How Much Do You Use Suppressed Weapons?";
}
break;
case 1:
{
question.text = @"Do You Like Sleight of Hand?";
answerA.text = @"Yes";
answerB.text = @"No";
[answerC setHidden:YES];
[answerD setHidden:YES];
[answerButton3 setHidden:YES];
[answerButton4 setHidden:YES];
}
break;
}
