Quick Newbie Question
Post: #1
Quick (hopefully) newbie question for anyone so gracious as to answer it 
.
so I have this written as part of a little test thing to see if I know what I'm doing (apparently not), I have all the labels connected properly in interface builder.
If you push a button in the UI, method pushButton is called, which calls the method roll, if I do the strLabel.text = newText in the setLabel method, it does not set the label properly, if I do it directly in the pushButton method it works fine. NSLog is there in setLabel to test it and it outputs correctly in the console.
What am i doing wrong?

Code:
-(void)setLabel:(UILabel *) label : (int)roll
{
NSString *newText = [[NSString alloc] initWithFormat:@"%d", roll];
NSLog(@"test, %i %@", roll, newText);
label.text = newText;
}
-(void)roll
{
GameViewController *myController = [[GameViewController alloc] init];
int stat = random() % 18;
while (stat == 0)
{
stat = random() % 18;
}
[myController setLabel: strLabel :stat];
}

I know you said that strLabel is connected properly, but that's the first thing I'd check.
If you see nil or null there, then strLabel is not connected.
Side notes: it's the typical style to have labels for all of the parameters in the method name. Also, you have a memory leak in setLabel since you init a string and never release it.
Code:
NSLog(" strLabel is %@ ", strLabel);If you see nil or null there, then strLabel is not connected.

Code:
-(void)setLabel:(UILabel *) label withNumber: (int)roll
{
NSString *newText = [[NSString alloc] initWithFormat:@"%d", roll];
NSLog(@"test, %i %@", roll, newText);
label.text = newText;
[newText release];
